Study of the Hydraulic Parameters of Existing Water Storage Structures in Bhakra Main Canal Command Area of Sirsa District, Haryana

Abstract

Balancing reservoirs are extensive kind of water storage structures. They ensure the adequate quantity of water availability to fulfill the demand and maintain water quality. The major hydraulic parameters of the tank are length, width, depth, side slope, surface area and storage capacity. In this study, information about hydraulic parameters of 109 existing balancing reservoirs was collected from various sources. The storage capacity of the balancing reservoir is important for the efficient operation of the water supply system. The balancing reservoir should be large enough to store sufficient water to meet both average and peak daily demands of the crop. In the present study, balancing reservoirs of different sizes and shapes were found existing in the farmers’ fields. Trapezoidal shaped tanks having a geometrical advantage over other shaped tanks can be constructed. Mostly, the B-category tanks (size between 50-100 m2) existed in research areas and these were based on the size of landholding. Water storage through the tank is considered as an efficient tool because it improves crop productivity and minimizes risk uncertainties.
