- Abstract
There is increasing concern to store water in on-farm reservoirs (OFRs) for meeting the supplemental irrigation requirements and (or) improving the irrigation efficiency of irrigation systems. The provision of OFRs leads to loss of a certain portion of agricultural land, but the economic viability of providing OFRs has been justified. As widely prevalent among designers, the volume of various shapes of OFRs is usually computed manually or using computer programs based on the trapezoidal or pyramidal formula. However, it has been found that the trapezoidal or pyramidal formula cannot be used for irregular geometries. For such cases, a method of superimposition has been proposed to compute volume accurately. A simplified approach is presented in this article for optimum design of OFRs. The relations between length and breadth are also developed for a variety of OFR shapes to guide farmers for minimum lining.
