Institute of Water Modeling or IWM, [1] is a government trustee of Bangladesh Water Resource Ministry and think tank that carries out research, planning and technology transfer related to water management projects in Bangladesh and is located in Dhaka, Bangladesh.
Surface Water Simulation Modelling Programme (SWSMP) launched in 1986 by the Ministry of Water Resources of Bangladesh Government under the Master Planning Organization to develop a high level of analytical capabilities by use of state-of-the-art mathematical water modelling which was the genesis of what at present is known as the Institute of Water Modelling (IWM).
It supports river hydraulic and storm drain models, lumped parameter, regression, 2D hydrologic modeling of watersheds, and can be used to model both water quantity and water quality. As of January 2017, supported models include HEC-1, HEC-RAS, HEC-HMS, TR-20, TR-55, NFF, Rational, MODRAT, HSPF, CE-QUAL-W2, GSSHA, SMPDBK, and other models.
Integrated Water Flow Model (IWFM) [1] [2] is a computer program for simulating water flow through the integrated land surface, surface water and groundwater flow systems. It is a rewrite of the abandoned software IGSM, which was found to have several programing errors. [ 2 ]
Watershed delineation is the process of identifying the boundary of a watershed, also referred to as a catchment, drainage basin, or river basin.It is an important step in many areas of environmental science, engineering, and management, for example to study flooding, aquatic habitat, or water pollution.
Hagekhalil has led the agency at a time of major initiatives, including negotiations aimed at addressing water shortages on the Colorado River, plans for building the water recycling plant in ...
IWM offers several techniques, including stormwater harvest (to reduce the amount of water that can cause flooding), infiltration (to restore the natural recharge of groundwater), biofiltration or bioretention (e.g., rain gardens), to store and treat runoff and release it at a controlled rate to reduce impact on streams and wetland treatments ...
Water quality models have different information, but generally have the same purpose, which is to provide evidentiary support of water issues. Models can be either deterministic or statistical depending on the scale with the base model, [2] which is dependent on if the area is on a local, regional, or a global scale. Another aspect to consider ...
