Estimating water budgets to determine the impact of changes in the land-use pattern

Last Updated on

Water budget analyses is an approach that emphasis on the transport, storage, and utilization of water on the surface of the earth. Ensuring sustainable water supplies requires knowledge about the movement of water(hydrologic cycle). Water budgets are tools that water users and managers use to quantify the hydrologic cycle. A water budget accounts for the rate of water movement and change in water storage in all parts of the atmosphere, land, and subsurface. Water budgets can be estimated to determine the impacts of any proposed or occurred changes in land-use and management, groundwater withdrawals, or reservoir management on water supply and water quality 1.

It is important to simulate the major components of the hydrologic budget to determine the impacts of proposed land management, vegetative changes, groundwater withdrawals, and reservoir management on water supply and water quality. As the acquisition of field data is costly and time-consuming, physical and empirical models have been created which uses satellite data to test various land use practices and their impacts on the hydrologic budget of watersheds. Satyukt analytics Pvt Ltd has developed proprietary models should that can simulate the individual components of the hydrologic budget.
