Assessment Scenarios of Water Resources Management in Arid Areas (Case Study: Birjand Plain, Iran)

摘要: Groundwater has often been considered one of the major sources drinking and agricultural water, particularly in arid semiarid regions. In this respect, present study dealt with a combination numerical models groundwater water resource management model. The first conceptual model was prepared to simulate table Birjand plain South Khorasan province, Iran. Then, level predicted verified using models. output these used investigate influence parameters such as climate change population growth rate on within WEAP scenarios discussed research included assessment demand saving underground resources by increasing growth, reducing planting area, drip irrigation method instead traditional practices until year 2020. results showed that area 20% 2020 an efficiency 90% would reduce 14% result, average 8.2 million m3 be saved from 2016
