4. Flood Prone Areas in Maharashtra
About 7% area of Maharashtra state is flood prone:
1. 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)
7. 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.

28. 1.The QPF, weighted QPF over the catchment, Real time Rainfall,
Climate, River water level and discharge and Reservoir Water level and
discharge data were disseminated twice/thrice daily basis to the Regional
Chief Engineers and Superintending Engineers in the Krishna & Bhima
basins to support the decision making.
2.Acess to the RTSF and ROS forecast is given to the authorities
(Regional Chief Engineers) of the basin.
3: The field organization was supported by providing Real Time data &
Forecasted results as per demand.
4. 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..)
