OUR VISION
•Optimal sustainable development, maintenance of quality and efficient use of water resources to match with the growing demands on this precious natural resource of the country.
OUR MISSION
•India is endowed with a rich and vast diversity of natural resources, water being one of them. Its development and management plays a vital role in agriculture production. Integrated water management is vital for poverty reduction, environmental sustenance and sustainable economic development. National Water Policy envisages that the water resources of the country should be developed and managed in an integrated manner.
Integrated Water Resources Management
31. Water resource is a vulnerable resource and its quality changes because of the following factors:
•Deforestation and poor land use practices in the catchment area, which disturb topsoil and vegetative cover resulting in decreased infiltration rates, increased runoff, sediment transport and deposition in rivers and storage reservoirs.
•Over abstraction of surface water sources at the upstream reduces the minimum flow required in the downstream sections for the sustenance of ecosystems and mangroves.
•Over pumping of groundwater induces saline water intrusion into fresh water aquifer resulting changes in groundwater quality with increased TDS.
•Water pollution due to discharge of untreated/partially treated industrial and municipal wastewater into water sources deplete dissolved oxygen and affects fish and other aquatic life. Agricultural drainage, which is carrying residues of chemical fertilizers and pesticides, affects the water quality, promoted weed growth and renders the water resources unfit for other uses.
•Encroachment of agricultural land and watersheds for urbanization and industrial development has impact on wetlands and important watershed areas and affects recharging areas and reservoir capacities.

34. Which H&H Modeling software should I use?
Dewberry-GRMC team proposes the HEC-RTS software.
Real-Time Simulation (RTS) programs are designed to seamlessly integrate meteorological data; and reservoir operation simulation, hydrologic, and hydraulic models into a calibrated, comprehensive, and standardized program.
Developed by the Hydrologic Engineering Center (HEC) of the United States Army Corps of Engineers (USACE)

Dewberry-GRMC team can help with customizing HEC-RTS, such as:
•Create grids using ArcTools instead of the GageInterp program
•Automate the RTS program to run on a six-hour interval
•Create an unsteady RAS model for critical locations
•Develop new solutions to limitations found in the RTS program, i.e. read temperature and precipitation forecast grids
