Flood Management & Watershed management
NECTAR has focused on technologies for real time monitoring of rivers with a decision support system for real-time forecasting of floods that integrates data management, monitoring, forecast modeling tools and dissemination methodologies in a single, user-friendly environment.
Based upon rainfall gauge data and satellite grid data, rainfall trends for each catchments and sub catchments are analyzed. Rainfall run-offs are performed to estimate total accumulated volume of water in each catchment for optimum water utilization. Several complex Mathematical models and advanced flood modeling tools were used for catchment water availability in Meghalaya. Slope, satellite based rainfall data , roughness coefficient and catchment area etc were used to accurate assessment of runoff through various simulation models to arrive at real time scenarios.
Flood model based on one day forecast was developed on Mahanadi River for Orissa. Backwater effect by raising the height of the Almati dam, on Krishna River was analyzed for Maharashtra Government. Inundation Maps were produced for Tapi River in Gujarat based on UKAI Dam discharge. Watersheds of Meghalaya are being worked upon to estimate the run-off and proposed effective water conservation strategy.
