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).
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.
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 ]
The software provides tools to automate various basic and advanced delineations, calculations, and modeling processes. [9] 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.
A study published in the Journal of Agricultural and Applied Economics in August 2000 stated that "GMS provides an interface to the groundwater flow model, MODFLOW, and the contaminant transport model, MT3D. MODFLOW is a three-dimensional, cell-centered, finite-difference, saturated-flow model capable of both steady-state and transient analyses.
An example of a non-discretized radial model is the description of groundwater flow moving radially towards a deep well in a network of wells from which water is abstracted. [7] The radial flow passes through a vertical, cylindrical, cross-section representing the hydraulic equipotential of which the surface diminishes in the direction of the ...
Soil and Water Assessment Tool (SWAT) is a free and open source hydrology model and GIS computer simulation sponsored by the USDA. SWAT is a well known geographic hydrological model in use by many universities and government agencies around the world, and integrates with commercial products like ArcGIS .
MODFLOW-OWHM [11] (version 1.00.12, October 1, 2016), The One-Water Hydrologic Flow Model (MODFLOW-OWHM, MF-OWHM or One-Water [12]), developed cooperatively between the USGS and the U.S. Bureau of Reclamation, is a fusion of multiple versions of MODFLOW-2005 (NWT, LGR, FMP, SWR, SWI) into ONE version, contains upgrades and new features and ...
