General Information about Real Time Stream Flow Forecasting - RTSF and Reservoir Operation System - ROS for Krishna-Bhima Basin - A Pilot Project
Under HP-II project, Real time data acquisition system (RTDAS) is installed and commissioned for Krishna and Bhima basin of the state. Real time decision support system consisting of real time stream flow forecasting and integrated reservoir operation system for Krishna and Bhima basin is also developed to manage the floods and operate reservoirs optimally for multiple uses. The conventional Hydro meteorological network (HIS) developed in HP-I, consisting of rainfall stations, river gauge stations, full climate stations, reservoir water level stations, spillway gates of reservoirs in Krishna Bhima basin is upgraded by installing different kinds of electronic sensors, data collection platform, solar panel, solar charger, batteries etc., and employing VSAT, GSM communication system to convey data in real time mode at an interval of 15 min to VSAT Master station/data center at Pune. This real time data and 72 hrs quantitative precipitations forecast on 9 km X 9 km grid, received from RIMES Bankok and NCMRWF, New Delhi is input for decision support system developed in HP-II. The real time DSS developed is now facilitating reservoir operators to act on time and prepare stakeholders for the floods. The water level, inflow and outflow forecast for reservoirs, forecast of river water level and flow is helping in taking the decisions for optimal operation of reservoirs well in advance. In addition, the reservoir operation system is facilitating in the optimization of the storages for ensuring flood cushion and improving agricultural productivity.
The Real Time Stream Flow Forecasting and Reservoir Operation System for Krishna and Bhima Basins is developed in consultation with DHI(India), Water and Environment Pvt. Ltd., New Delhi as a prime Consultants with DHI, Denmark and Riverside Technology USA as sub consultants.
Modeling system developed in project is built upon the customized MIKE model and consists of
Sequence of Steps in Forecasting System
The real-time stream flow forecasting was shared with reservoir managers from monsoon 2013. The Real Time Stream flow forecast for viewing/use of all stakeholders of the basin is made available on website; http://www.rtsfros.com/mahakrishna in Real time Forecast menu.
