Ganges River Flow Benefits for Bangladesh †How to Estimate It?

Ganges River Flow Benefits for Bangladesh How to direct it? Zaman A. M. , Haque A. K. E. , Rahman S. M. M. , Mohiuddin F. A. Abstract For economic simulation in the Ganges Basin, an estimate of the weewee demand in the Ganges bloodsucking Area (GDA) in Bangladesh is required. This paper outlines a method for estimating this peeing system demand. The proposed method is establish on the integration of hydrological and hydraulic offshoot models with economic models.In Bangladesh, a manakin of mathematical models are currently employ to estimate the impacts on Bangladeshs pee resources system for different upstream operate conditions, local hydrologic situations, Bay of Bengal circumstances, etc. The models allow in basin level hydrological models, 1-dimensional and 2-dimensional hydrodynamic models, structural model, salinity model, Bay of Bengal model, etc. The first gear tint in the proposed method it to determination these models to simulate a range of hydrologic and hydraulic scenarios in the GDA in Bangladesh.The next step involves using the outputs from these physical process models as inputs to economic models that estimate the economic take ins (and costs) in the GDA. These economic models leave behind focus on different sectors that can potentially benefit from additional freshwater flows to the region, e. g. irrigated agriculture, open-water and capture fisheries, navigation, ecosystem operate (particularly the Sundarbans), dredging of river channels, water logging in polder areas, water supply, etc.For example, currently there is very much no flow into the Gorai River, a advert river in the GDA, from the Ganges during the months of January to May. As a result, there is increase river salinity and depositary in the southwest region. Additional flows will not only allow increased agriculture production and improve water supply options but also conquer the costs of regular dredging of key rivers in the region. These estimated benefit s represent economic water demands for the GDA in Bangladesh.
