Abstract

Integrated simulation of water resources systems is an efficient tool to evaluate and adopt various options in macropolicies and decision-making procedures that are in line with the sustainable development of drainage basins. One of the drainage basin management policies is to enhance the efficiency of agricultural land use. Considering the complicated function of the drainage basin elements and their interaction with each other due to water Discharge fluctuations caused by various factors such as climate change, the evaluation of these policies is of great importance. Given the low Irrigation Efficiency in Iran, the present study was aimed to evaluate the effects of management scenarios (including long-term Irrigation Efficiency increased up to 20% with 5% intervals) and Discharge fluctuation scenarios (including 5% and 10% decrease in the average basin inflows) on the Reliability and Vulnerability of water resources system in Dez Basin. The integrated scenarios were simulated in the WEAP model. The scenarios were separately simulated for the Dez irrigation network and all farmlands across Dez Basin. According to the results, Reliability was decreased by 5. 69 and 18. 89% in the scenarios with 5% and 10% decrease in the average basin inflows, respectively. Furthermore, the Irrigation Efficiency of 20% in the scenario considering the current inflows ended up with the Reliability of 73. 58%. Moreover, in the scenario involving 5% decrease in the average basin inflows, the Reliability was increased by 3. 8% with an increasing efficiency of 20%; with 3. 8% and 5. 7%, there was an increasing efficiency of 15% and 20% in all farmlands, respectively. In the scenario consisting of 10% decrease in average basin inflows, the Reliability was increased by 1. 91%, 3. 8%, and 5. 7% with the increasing efficiency of 10%, 15%, and 20%; on the other hand, with, these were 3. 8% 9. 46%, and 13. 2% with increasing efficiency in all farmlands, respectively. In all scenarios, the Vulnerability was found to fluctuate between 25% and 31%, which was systematically analyzed.
