ALLOCATION OF WATER RESOURCES IN UPPER BRAHMANI RIVER BASIN

Abstract

The aim of the combined Reservoir operation to allocate available water resource to different project in Orissa namely, itamahal Irrigation Project, Kansbahal Irrigation Pro-ject, I"Iandira Dam Project, Barsuat Irrigation Project and Lodani Ira°igacion Project in upper Brahmani Basin keeping inview the upper and lower riparian rights of Bihar state and Rengali multi-purpose pLoject and to evolve optimal cropping pattern for Lodani Project. In the present study, the operation is eaaried out by using, simulation technique to find out allocation of water to differ,-_-nt reservoirs in upper Brahamani Basin in conjunction with linear pro~ra_ ruing model, which determines the dif .erent optimal cropping; pati-ern or achieving above objectives Reservoir operation model was used in conjunction with linear prod ram:ping model. he reser-voir opera'Gion was run in six steps with dif .erent crop water requiremen± s i.e0 as per state government suggested cropping pattern and cropping pattern evolved from the linear programming model. i_'rom the above study the cropi ing pattern evolved by step..IT-i.e. with Iihariff crops areas, vegetables 726.7 hectares, :Medium paddy 155918.3 hectares and with Rabi crops areas, Pulses 4'•7o hec-ca~es, vegetables 2423 hectares appears to the best among six alternatives.
