meghna river discharge

However, studies on the impact of monsoon-driven fluctuations of river discharge are limited. The Ganges and Brahmaputra rivers flow across many different rock types. During dry season, the river discharge is much lower than monsoon; saline water entire and crop could not be grown. Here, we present a framework for downscaling precipitation from global climate models for river discharge in the Ganges-Brahmaputra-Meghna basin. The catchment area is 1,520,000 km². Some of the measurements done during the Meghna Estuary Study project suggest that in an extreme year, discharge through the estuary can be as much as fifteen times during the monsoon season compared to that during the dry season [3]. is crucial for tracking the flow direction and defining the river network in a basin. For a detailed view, please see the map below: During the monsoon period (June-October), the volume of water often exceeds the carrying capacity of these rivers, and fluvial flooding occurs. show the yearly maximum discharge for different return periods. In Daudkandi of Comilla district, the Meghna river is joined by the Gumti River, which increases the Meghna's water flow considerably. However, studies on the impact of monsoon-driven fluctuations of river discharge are limited. Ganges - Brahmaputra - Meghna. The area of early Meghna delta is about Meghna river delta (Fig. 630 million people [8] (Figure 1a). Climate change scenarios were constructed from the results of four . In general, there is a total annual river discharge inflow into the GBMD from India of 1,110.6 km3 (FAO, 2016). The Gorai River in the western part, the Arial Khan River and the distributaries of the Meghna river in the eastern part are the primary sources of fresh water flow. the Meghna River. The Meghna river is reinforced by the Dhaleshwari river before Chandpur The Amazon River is found in the continent of South America and is the largest river in the world regarding discharge by volume. The combined rivers discharge through the Meghna estuary into the Bay of Bengal. Cholera is an acute diarrheal disease caused by the bacterium Vibrio . Major charac-teristics of the GBM Rivers are presented in Table 1. These hydrodynamic factors and their interactions shape the morphology of the lower Meghna River. The hydrodynamic factors that are playing dominant role in morphological development along . The Ganges, Brahmaputra and Meghna (GBM) basin and numerous minor rivers provide the main freshwater flow into the northern and central part of Bangladesh (see Fig. In this study, the performance of a 1-km resolution DHM is compared with that of a 90-m resolution DHM in simulating the discharge of the Meghna River in Bangladesh. Riverbank sediment cores and pore waters, shallow well waters, seepage waters and river waters were collected along the Meghna Riverbank in Gazaria Upazila, Bangladesh in Jan. 2006 and Oct.-Nov. 2007 to investigate hydrogeochemical processes controlling the fate of groundwater As during discharge. 1) contains >50 juig/L As (1). VARIABILITY AND THE GANGES-BRAHMAPUTRA RIVER DISCHARGE A Thesis Presented to The Academic Faculty By Jun Jian In Partial Fulfillment . Figure 1. The study area, Mehendiganj Island, is . A little above the confluence, Meghna has a railway bridge over it. (This is lower than the recharge rate because groundwater also discharges via evapotranspiration.) A joint institutional setup is proposed, with the Based on several past studies, the combined mean annual sediment load of the Ganges-Brahmaputra-Meghna (GBM) systems has previously been estimated to vary from 1.0 to 2.4 BT/year which can be separated into components flowing from the Ganges (260 to 680 MT/year) and Brahmaputra (390 to 1160 MT/year). The Brahmaputra River contributes nearly half of the ~40,000 m 3 /s mean annual discharge of the Ganga-Brahmaputra-Meghna river system (Fig. The knowledge about the physical processes and morpho-dynamic behavior of the Lower Meghna Estuary is still fairly limited. In this study, the changes in precipitation of Sylhet and river discharge of Surma River and the relationship between them were investigated. 2 . In terms of deaths and . Tidal influence extends to more than 50 km inland from the shoreline and surges increase considerably during the cyclonic storms (Gopal and Chauhan 2006 ). through the Lower Meghna River. The Meghna River has the upper and lower parts divided at the confluence point with the Ganges. The Amazon River. 1 ). It is bounded on the west . To assess the fate of As during discharge, surface (0-5 cm) and subsurface (1-3 m) sediment samples were collected at 9 sites from the bank of the Meghna . The Ganges River, one of the biggest rivers in the world, also known as 'Ma Ganga' with the combined flows of Brahmaputra and Meghna rivers could be responsible for up to 3 billion microplastic particles entering the Bay of Bengal each day, said a new team of international researchers and scientists. It is often considered as a delta mostly exposed to sea-level rise and exacerbated by land subsidence, even if the local vertical land movement rates remain uncertain. The Ganges-Brahmaputra-Meghna river system is the largest river system in the world with massive discharge rates and sediment loads (annually over one billion tons). In the early Holocene, vigorous delta aggradation occurred under rapid sea-level rise and high river discharge and supported the construction of sand . The land traversed by the The Meghna River is the third largest river on the Ganges-Brahmaputra-Meghna (GBM) delta. The net discharge through this river varies from 10,000 cumec in the dry season to 160,000 cumec in the wet season." The river is linked with the Lower-Meghna through the Tentulia in the north-east, flows to the south and finally falls to the Bay of Bengal through the Bishkhali/Burishwar estuarine mouth. The downstream of surmariver from Ajmiriganj is often referred to as the Meghna. The length of river reproduced in the . Sampling procedures were performed in three phases: firstly, September, 2015 (Rainy season); secondly, January, 2016 (Winter season) and thirdly, March, 2016 (Pre-monsoon). : Mississippi River) ist ein 3778 Kilometer langer Strom in den Vereinigten Staaten.Er entspringt dem Lake Itasca im nördlichen Minnesota und mündet rund 160 Kilometer südlich von New Orleans in den Golf von Mexiko.. Sein längster Nebenfluss Missouri ist bis zur Mündung deutlich länger, jedoch wesentlich wasserärmer als der Mississippi. The Mechanism of the Freshwater Outflow Through the Ganges‐Brahmaputra‐Meghna Delta Shinichiro Kida1 and Dai Yamazaki2 1Research Institute for Applied Mechanics, Kyushu University, Kasuga, Japan, 2Institute of Industrial Science, The University of Tokyo, Tokyo, Japan Abstract The Ganges‐Brahmaputra‐Meghna (GBM) delta is a major source of freshwater for the Bay of It is a tidal reach carrying almost the entire fluvial discharge of Ganges, Brahmaputra and Upper Meghna river. In the GBM delta, river water is used to irrigate crops, and in recent years there has been an increase in river salinity (Dasgupta et al, 2014). It is the 9th largest river in the world by discharge, and the 15th longest. There are 165 industries in the immediate upstream at Khulna district. 2. The average flow rate at the mouth of the Amazon is sufficient to fill more than 83 such pools each second. To measure the metal concentrations and human health hazards, edible tissues of 15 commercially important fish species were collected f … The Lower Meghna River region of Bangladesh is a unique environment where the constant process of land formation and erosion takes place due to the complex interactions between large river discharge, enormous sediment load and strong tidal forces. Since datasets might show constraint at coarse resolution, a ground validation is proposed. The discharge of the Ganges also differs by source. 8.1 At a point near Bhola, Meghna is 13 km wide. Piecing together the Ganges-Brahmaputra-Meghna River delta: Use of sediment provenance to reconstruct the history and interaction of multiple fluvial systems during Holocene delta evolution . Sediment from these rivers has formed one of the largest and most densely populated deltas in the world. During monsoon, river discharge, water levels and SCC in the river reaches with RDF and MF . The high river discharge and its seasonal variations also modulate river salinity in the GBMD. An important linkage with the agriculture was established by finding agro-chemical pollution - insecticide dimethoate, herbicide diuron, and fungicide carbendazim in . With a discharge of up to 138,700 m3/s of Climate change in the future would have implications for river discharges in Bangladesh. The major rivers are: Padma, Meghna, Brahmaputra, Surma, Jamuna, Karnafuly etc. Fig. The downstream of surma river from Ajmiriganj is often referred to as the Meghna. The geographical coordinates of the early stage (1) the early stage of Brahmaputra river delta; (2) the early Meghna River delta is 22.15 N latitude to 91.10 E longi- stage of Ganges river delta and (3) the early stage of tude. This river system is the world's third largest freshwater outlet to the oceans (Chowdhury and Ward, 2004). The Meghna Estuary of Bangladesh experiences dynamic morphological changes due to heavy sediment discharge from the Ganges, Brahmaputra and Upper Meghna Rivers with annual rate of nearly billion tons. Loading of municipal wastes (raw sewage and solid domestic wastes) from Khulna and Mongla port entering the Pasur river is estimated to be 2.2 tons of BOD/day . A part of the Surma-Meghna River System, Meghna is formed inside Bangladesh in Kishoreganj District . Meghna River one of the major rivers in Bangladesh, specially famous for its great estuary that discharges the flows of the Ganges-Padma, the Brahmaputra-Jamuna and the Meghna itself. River Ganges. Infectious diseases Full text in pdf format . The area is periodically subject to severe storms and cyclones. The Meghna River discharges 500 m 3 /s in the dry season ( 1 ), most of which probably represents groundwater discharge, and therefore an annual discharge rate is estimated to be 250 m 3 /s, equivalent to 0.2 m per year. The river joins the Brahaaputra after another 110 kilometer or near Goalanda Ghat in Bangladesh in the name of the Padma and farther down the combined discharge joins the Meghna at Chandpal ghat after going another 70km or so and the combined watercourse is called the Meghna. This change has potential consequences for land use practices and livelihoods for the . The 1a), located between 22°3.5' and 31° 50'N latitudes and 73°10.5' to 97°53'E . Congo River. The hydrology of the lower GBM Delta is domi-nated by the freshwater flows from upstream Ganges, Brahmaputra and Meghna Rivers, which exhibit very high seasonal variation in their discharge. The Meghna River discharges 500 m3/s in the sediment As enrichment is found to be widespread, then it dry season (1), most of which probably represents groundwater represents part of an As cycle that is also responsible for elevated discharge, and therefore an annual discharge rate is estimated to As in groundwater. To assess the fate of As during discharge, surface (0-5 cm) and subsurface (1-3 m) sediment samples were collected at 9 sites from the bank of the Meghna River along a transect from its northern source (25 degrees N) to the Bay of Bengal (22.5 degrees N). It is a tidal reach carrying almost the entire fluvial discharge of Ganges, Brahmaputra and Upper Meghna river. The three rivers have a drainage area covering 668,472 square miles and have an average discharge flow approximately 1,346,513 cubic feet per second and finally discharge into the Bay of Bengal. The Congo River is Africa's second longest river and the world's second-largest by discharge volume. The combined river, known as the Lower Meghna, discharges through delta channels into the Bay of Bengal. With an average freshwater discharge of around 40,000 cubic metres the GBM (Ganges Brahmaputra and Meghna) river system has the third largest discharge worldwide. 2 . The combined discharge of these three major rivers is among the highest in the world. Previous. The minimum water flow of the Meghna River is 3750 m 3 /s (Figs. GEOGRAPHICAL LOCATION AND DATA The Ganges-Brahmaputra-Meghna (GBM) river system (Fig. Their average annual combined discharge into the Bay of Bengal is 100,000-140,000 m 3 /s carried by Ganges-Brahmaputra-Meghna (GBM) Rivers (EGIS 2000 ). Also referred to as "Ganga", the Ganges River is a long transboundary river in the Continent of Asia that flows through some of the most densely populated regions in the two major countries of India and Bangladesh.Rising in the western Himalayas in the Indian State of Uttarakhand, the Ganges River flows for more than 2,525km across the Gangetic Plains in the northern part of . This system was chosen because most of the shallow groundwater As east of the Meghna River between 22 and 24° N (Fig. 1.1 Description of Ganges-Brahmaputra-Meghna River System Bangladesh occupies an area of about 145,000km 2 between latitudes 20.5˚N and 26.75˚N, and longitudes 88˚E and 92.75˚E. Bulk As concentrations of surface sediment averaged 16 {+-} 7 mg/kg (n = 9). Representative Studies of River Discharge and ENSO River discharge in SE Australia has previously been shown to be strongly influenced by ENSO cycles. The sediment discharge from the Lower Meghna River is the highest (Coleman, 1969) and the water discharge, the third highest, of all river systems in the world (Milliman, 1991). Meghna River, GEOSS/AWCI demonstration basin, in Bangladesh to assess river discharge. Here, the role of varying river discharge on the tidal propagation and tidal limit along the Ganges-Brahmaputra-Meghna Delta (GBMD), a macrotidal estuary subject to seasonal and annual river discharge variations, is investigated. The upper Meghna River is small compared to the Ganges and Brahmaputra Rivers, with an average annual discharge of only 3,510 m 3 s −1 (Parua, 2010). Significance Of Rivers. Since datasets might show constraint at coarse resolution, a ground validation is proposed. In this study we attempted to quantify the contribution of groundwater discharge to the Meghna River using three independent approaches, namely: differential gaging, hydraulic gradients and a tracer mass-balance method using radon-222. Results Aquifers in the GBMD. These releases occur for 10-20 days each summer and account for 30-45 % of the river's annual sediment discharge and 15-60 % of its annual water discharge, both of which are less than 15 % of . The first flood peak in the Upper Meghna typically occurs in the second or third week of May. Meghna River, GEOSS/AWCI demonstration basin, in Bangladesh to assess river discharge. The wastes from these industries fall into the Bhairab-Rupsha river system, which ultimately find their way to the Bay of Bengal through the Sundarbans. Cite this article as: Nasr-Azadani F, Unnikrishnan A, Akanda A, Islam S and others (2015) Downscaling river discharge to assess the effects of climate change on cholera outbreaks in the Bengal . Bangladesh faces different types of natural cyclones every year. However, studies on the impact of monsoon-driven fluctuations of river discharge are limited. estimate river discharge. . Here, the role of varying river discharge on the tidal propagation and tidal limit along the Ganges-Brahmaputra-Meghna Delta (GBMD), a macrotidal estuary subject to seasonal and annual river discharge variations, is investigated. Meghnaghat area which supported reduced wastewater discharge. Meghna River is wholly in Bangladesh and forms the largest delta in the world fanning out into the Bay of Bengal. 1).This makes it the joint third largest river . In the dry season, the shallow groundwater discharges to major rivers. The Padma River (Figure 1) flows southeast for approximately 100 km from the Jamuna-Ganges confluence to join the Upper Meghna River flowing from the northeast. The morphology of the Meghna estuaries is dominated by many rivers, discharge of river water with high sediment, a large number of islands, chars and sand bars; a shallow and wide estuary; a narrow strip of coastal landforms . The water flow patterns also shift in the Meghna River estuary. discharge area and far from the discharge area) of Meghna River near Narsingdi District (23º55'28.52"N and 90º45'12.06"E). The input rainfall was obtained from the Tropical Rainfall Measuring Mission (TRMM). In the Ganges, the MSWEP data sets seem to overpredict the discharge, and in the Meghna River, the peak in the seasonal cycle occurs early relative to the observations. tries. In this article, possible changes in the magnitude, extent and depth of floods of the Ganges, Brahmaputra and Meghna (GBM) rivers in Bangladesh were assessed using a sequence of empirical models and the MIKE11-GIS hydrodynamic model. This results in a total average annual discharge of about 38,000 m3/s (1,300,000 cu ft/s), or 42,470 m3/s (1,500,000 cu ft/s). Since rivers act as corridors for transport of cholera bacteria, the first step is to understand the discharge variability that may occur with climate change and whether it is linked to cholera. We quantify discharge exchange and tidal waveform propagation in the interconnected Shibsa-Pussur tidal channel network on the southwestern Ganges-Brahmaputra-Meghna Delta, with the goal of characterizing the natural system's response to anthropogenic landscape modification. The combined daily river discharge, carried by the Ganges, Brahmaputra and Meghna rivers into the Bay of Bengal, was applied as one river outlet in the simulation. In summary, the goal of this paper is to contribute to river discharge assessment using available global datasets through an application to a large river basin. Here, only those rivers are shown whose discharge is more than 2,000 m 3 /s (71,000 cu ft/s). For context, the volume of an Olympic-size swimming pool is 2,500 m 3. 2.2. Discharge of river water into the Meghna estuary at different seasons is highly skewed. As a whole the Brahmaputra (Jamuna) River carries water flow 60,000-100,000 m 3 /s. The Estuary conveys the joint discharge of the Ganges/Padma, Jamuna/Brahmaputra, and Meghna Rivers. Therefore, if it is intended to . Significance Of Rivers t per year) pass the area. Hereby, large volumes of water (some 1,200 km³ per year) and sediment (some 1,100 mio. river stretch of the Lower Meghna river starting from the confluence. This process may influence the chemistry of the river and the hyporheic zone sediment. The location of river input was set near Hardinge Bridge on the Padma River (24.0679 °N, 89.0297 °E, marked SW90, Fig. It is of interest to note here that the sediment discharge from the river Meghna (combined flow of the Ganges-Brahmaputra-Meghna) is the highest and the freshwater discharge is the third highest of all the river systems worldwide . Frequently, discharge is described for the mouth of the Meghna River, thus combining the Ganges with the Brahmaputra and Meghna. The Meghna River is one of the major rivers in Bangladesh, one of the three that form the Ganges Delta, the largest delta on earth, which fans out to the Bay of Bengal. While the discharge within the Lower Meghna (the part downstream of the confluence near Chandpur) typically varies between 8,000 m 3/s in February-March and 100,000 m 3/s in July to September, the peak discharge 2, 3 ). Cyclones. In summary, the goal of this paper is to contribute to river discharge assessment using available global datasets through an application to a large river basin. The sediment discharge from the Meghna River is the highest and the water discharge is the third highest among all the river confluences in the world. R … Meghna Estuary is the easternmost sector of the Ganges delta. Meghna River বাংলা Meghna Riverone of the major rivers in Bangladesh, specially famous for its great estuary that discharges the flows of the Ganges-Padma, the Brahmaputra-Jamuna and the Meghna itself. Being one of the most vulnerable regions in the world, the Ganges-Brahmaputra-Meghna delta presents a major challenge for climate change adaptation of nearly 200 million inhabitants. 1.4. The upper Meghna River is small compared to the Ganges and Brahmaputra rivers, with an average annual discharge of 0.35 × 10 4 m 3 s −1 (Parua, 2010). Annual discharge-gauging records covering about a century for each of five rivers in this region (Darling (log Q), Lachlan, Loddon, Upper Murray, and Murrumbidgee) have signifi- Bangladesh is known as a deltaic plain at the confluence of the Ganges, Brahmaputra and Meghna River Basins (GBM) and their tributaries. Erosion and accretion rates are high and the area is periodically subjected to severe storms and cyclones. The right-hand-side panels in Fig. The Meghna River is a comparatively smaller, rain-fed, and relatively flashier river that runs through a mountainous region in India before entering Bangladesh. The Meghna River drains mainly lowland deposits of Himalayan alluvium in Bangladesh. The key is the river discharge and regional climate," says Professor of Civil and Environmental Engineering Shafiqul Islam. The matter would be simpler but for the fact that from Madna downstream for . The lower Meghna River, the easternmost part of the Ganges Delta, faces severe anthropogenic perturbations as it receives a huge discharge and industrial effluents. 8.1 ). (This is lower than the recharge rate because groundwater also discharges via evapotranspiration.) Groundwater arsenic (As) is elevated in the shallow Holocene aquifers of Bangladesh. Our results have important implications for cycling of As in deltaic environments and groundwater discharge as a source of elements to the ocean. Next. It drains the combined Ganges, Brahmaputra and Meghna rivers, where the vast majority of discharge eventually makes its way to the main trunk of the Lower Meghna river/estuary in Bangladesh and into the Bay of Bengal. Due to the high sediment discharge, lands are eroded and reformed. Here, the role of varying river discharge on the tidal propagation and tidal limit along the Ganges-Brahmaputra-Meghna Delta (GBMD), a macrotidal estuary subject to seasonal and annual river discharge variations, is investigated. We assumed the river salinity to be 0. 4). 18,299.55 km2. The river flow in southwest Bangladesh is affected by tides entering from the south. The rainfall pattern of northeastern part of Bangladesh is changing along with the discharge pattern of Surma River. Meghna is the widest river among those that flow completely inside the boundaries of Bangladesh. It is also found that the dredged channel is partially silted up at average annual discharge (30,000 cumec) but at 100-year return period discharge (1,30,000 cumec), it is almost fully silted up. The net discharge through this river varies from 10,000 cumec in the dry season to 160,000 cumec in the wet season. The sediment discharge from the Lower Meghna River is the highest and the water discharges the third highest, of all river systems in the world . Der Mississippi [ˌmɪsɪˈsɪpɪ] (engl. The Meghna River discharges 500 m 3 /s in the dry season , most of which probably represents groundwater discharge, and therefore an annual discharge rate is estimated to be 250 m 3 /s, equivalent to 0.2 m per year. The objective of this study is to determine: 1) the extent of mixing between river 124 water and groundwater driven by ocean tides, seasonal river level fluctuations, and irrigation pumping, 125. The Meghna River, located 30 kilometers east of Dhaka, is abundant in supply, reasonably clean, and could be . Meghna River, (b) plot-wise ECA map of the selected segment of the Meghna River, and (5) assessed and reported . Around 2 km reach of 6.5 km long sedimentary deposit is taken as the study site at the downstream of the existing ferry ghat at which Lebukhai bridge is . Meghna river basins were considered at the Hardinge Bridge, Bahadurabad and Bhairab Bazar gaging stations of Bangladesh Water Development Board (BWDB), respectively, so that the observed discharge data from these locations can be compared with the SWAT generated discharges in order to calibrate and validate the model. Previous studies for the GBM have predicted increases in future peak river discharge [ 14 - 18] and flood extent [ 19 ]. Recent studies [ 3, 20 - 22 ], looked at flood risk at 1.5 °C and 2 °C of global warming, for changes to peak discharge of the Brahmaputra or global flood risk including the Ganges-Brahmaputra. A logistical regression model was later calibrated and validated for 2 sea-sonal peaks of cholera in Bangladesh using river dis-charge data. discharge and pesticide use, collaborating with local administration, and empowering local stewardship at the Meghna River catchment are key approaches recommended.
