Description

The overall goal of the National Water Management Plan (NWMP) is to describe and evaluate water availability and demand for agricultural, industrial, domestic, environmental and other purposes and the future water balance; in-stream uses, their requirements and the constraints they impose on water management; water quality, pollution and sanitation services, salinity intrusion and protection of the natural environment; and international rivers at border entry points and their particular characteristics and constraints. In order to achieve the objective of the plan, SWMC provided the support services related to mathematical modelling and database.

Major activities carried out by SWMC under NWMP include (i) Flood Hydrology Study to determine representative period for model simulation over a long historical period, (ii) Flood Management Modelling to simulate water level and discharge at the model grid points, based on which flood levels, flood depth maps & depth duration maps under various return periods have been produced, (iii) develop and simulate hydrodynamic model for low flow condition to assess the flows in the rivers for dry period under various development conditions, (iv) surface water-groundwater interaction model on a pilot area for the assessment of the groundwater, flow interaction between the aquifer and the river under various scenarios, (v) salinity modelling to simulate the salinity level and its intrusion into the river system of coastal areas of Bangladesh under various upstream flow conditions to bring the salinity to the desired level, (vi) contribute in the development of National Water Resources Database, (vii) web-page for WARPO, (viii) design and installation of computer networking system in WARPO and (ix) transfer of technology to WARPO staff through a comprehensive training programme including both on-the-job and theoretical training on various types of mathematical modelling and databases.
