Integrated Planning of Water Resources Based on Sustainability Indices, a Case Study: Hamoon- Jazmorian Basin

Abstract

Nowadays, the water supply and water demand management are the main issues in water resources planning. It is more important in a river basin with a complex system facing with droughts, climate changes, inter-basin water transfer and operational and under study dams. In this paper, for water resources planning in a river basin and reducing the difference between water resources and water demands, the river basin conditions are assessed under different scenarios. In order to simulate the water resources and demands in the future, the MODSIM is used for river basin modeling. To calibrate the developed model, historical values of groundwater table fluctuations in different plains and flow changes in different hydrometric stations, are compared with the results of MODSIM. Then some indices based on three criteria including water and environmental resources sustainability, economic sustainability and social equality are defined to evaluate the scenarios. The indices are quantified and explained in current and future conditions. The results show the higher performance of Scenario 4 including the execution of under study projects along with demand management and aquifer restoration.
