Abstract

The utilization of water resources models enables correct and sustainable planning in water resources management. The purpose of this study is to optimize the use of water resources in the catchment area of Varamin plain for 10 years under different management scenarios. To achieve optimal conditions in the volume of water resources, the minimization of non-supply needs and the needs of different land use in Varamin plain were studied. Accordingly, the situation of water resources in Varamin plain in three sectors of agriculture, industry, and drinking using WEAP model under two scenarios: a- reference with prioritization of the ministry of energy and b- scenario of reducing inlet volume by changing prioritization in the period 2016-2026  Solar was evaluated. The climate of the region was studied based on the model of the blue year (flow, precipitation, evapotranspiration, temperature) and entered the model. The results showed that according to Scenario A, we will have a 30% shortage of drinking water supply in the region, and this is 37% for the scenario of the reduced input volume. Based on the results, the reference scenario, which in terms of meeting different needs and reliability index of water needs and maximum volume of water not provided during the statistical period, compared to the scenario of the reduced input volume, has a better performance for the Varamin plain, It was considered as the preferred scenario.
