Analysis of Latiyan Dam Catchment's Water Resource Condition Based On DPSIR Conceptual Model

Water resource evaluation is considered as one of the fundamental steps in water resource management. DPSIR framework assists water resource decision makers with evaluating main reasons led to current conditions to fundamentally address related problems.The DPSIR analytical framework is not new but developed from the pioneering work by the Organization for Economic Cooperation and Development (OECD) in the 1980s, and was published in the early 1990s. In this study, based on DPSIR framework, a conceptual model for evaluating current water resource condition in Latiyan dam catchment is proposed to integrate environmental and social-economic indexes. Finally, after assessing the Latiyan dam catchment’s water resource condition, appropriate responses are suggested to tackle water resource condition in the region. These responses will remove or reduce the undesirable effects of natural and human reasons on water resources. The results show that increasing in Tehran’s annual average of daily temperature by 1.50c during past 50 years as well as Tehran’s population growth of more than 11 times in the same period results in falling Tehran’s groundwater surface elevation that according to changes’ trend in climate change and water quality parameters, the groundwater surface decline is more of human driving force
