Mumbai (Mithi river) & Thane Metropolitan cities (July 2005) 2.Konkan Region - Vashisthi river (Chiplun), Savitri river (Mahad 1923,1976,1989,1994)), Amba river (Nagothane, Pen), Ulhas river 3. Krishna basin- Krishna, Panchganga, Warna (Sangli and Kolhapur 2005, 2006), Mula, Mutha (Pune), Bhima (Pandharpur 2006). 4. Godavari Basin- Godavari river (Nanded 1962, 1969, 1973, 1975, 2005), Wainganga (Bhandara district 2006 and Brahmapuri taluka (Chandrapur ), Conflulence of Wardha and Penganga (Chandrapur proper) (August 1979). 5. Tapi basin- Tapi (Jalgaon district) 4. District Crops & Infrastructure Land/ Structure Damages Horticulture Total Farmers SAU's Crops Govt.

RESERVOIR OPERATION IN MAHARASHTRA The reservoirs in Maharashtra are multipurpose including hydropower, irrigation, domestic and industrial uses. Though these reservoirs are not specifically provided with flood cushion, they have moderated flood peaks to considerable extent by proper reservoir operations. Reservoirs are operated with rigid schedules as single entities based on the historical hydro-meteorological data and experience gained. These methods are often not adequate for establishing optimal operational decisions, especially where integrated operation of multiple reservoirs for flood management is contemplated. In addition, manual data observation and transmission results in a considerable time lag, between data observed in field and its communication to decision making level which sometime leaves little time, for flood forecasts. Therefore WRD Maharashtra has installed the RTDAS and developed the RTSF and ROS model for Krishna and Bhima basins of Maharashtra under World Bank aided HPII project. 6.

Awareness raising activity regarding use of model is initiated with demonstration of system at WALMI, META, MKVDC, YASHADA, HP. Now Field organizations are actively involved in use of the system. 5. Real time web application for RTDAS is developed. (live demo..) 15. 29 16. Comparison of Simulated and Observed Discharges for Koyna Catchment (R2=0.95, Wbl=0.00% (Obs=5660mm/y, Sim=5660mm/y)) 17.
