Water Demand and Supply Analysis using WEAP Model for Veda River Basin Madhya Pradesh (Nimar Region), India

Abstract

Significant gaps exist in water management strategies implemented in the sub-basin of Narmada River, the Veda River Basin. Hence, the main goal of this study is to predict water demand and supply, recharge and draft with the use of the Water Evaluation and Planning System (WEAP) Model. The study area is watershed of the Veda River located in the Nimar region of Madhya Pradesh, and Middle Narmada River sub-basin of India. In this study, the WEAP model is used as a decision support system for watershed management. The WEAP model uses water balance approach for the generation of results, based on that 4 types of scenarios have been developed are high population growth, high industrial growth, rainwater harvesting, and water storage structures for future trends. The unmet water demands were simulated in all administrative blocks, catchments, and industries which amounting to 9.58×108 m3 in 2011 and 9.65×108 m3 in 2030. Results suggested that the addition of water storage structures as well as artificial groundwater recharge structures reduce the unmet water demand for domestic consumption and meet irrigation water requirements.
