SYSTEMS ANALYSIS OF KRISHNA IRRIGATION PROJECT

Abstract

Day by day the issue of making use of resources available judicially is becoming essential. In case of water resources projects attempts have to be made to utilise the main resources, i.e., land and water optimally. In this context, water resources systems analysis has now been generally accepted to provide an efficient way of answering the numerous questions regarding planning of complex water resources systems for which the conventional methods of analysis will be inadequate. The approach and appropriate technique will naturally vary from problem to problem as the configuration, state of development of the system and stage of decision making is likely to vary over a vast range. The most commonly suggested approach has been first to screen all alternative configurations with mathematical programming technique .o determine the most attractive alternatives then further screen them with a detailed simulation. In the present study an attempt has been made to carry out the systems analysis of Krishna Irrigation Project, Maharashtra state. The Krishna Irrigation Project (Maharashtra) consists of two parallel reservoirs namely Dhom and Kanher. This project envisages the total irrigation of 74,000 ha irrigable command area (ICA) with canal network consisting of five main canals. The irrigable command area (74,000 ha) consists of the ICAs of both reservoirs (Dhom = 32,925, Kanher = 10,070 ha) and one additional command in arid zone in Sangli district called as Arphal command (31,005 ha). The Arphal command has been proposed to be irrigated by diverting the water from both reservoirs. In addition to this, there is demand of municipal and industrial (M and _ I) water supply in Satara district. So far as stage of development is concerned, the construction activity of project is almost completed except few kms of A.L.B.C. and irrigation in Dhom and Kanher command is already commissioned.
