Study of Integrated Urban Wastewater Impacts on Groundwater Levels Influenced Climate Change Effects on 2020-2014 (Case Study: Birjand Plain)

The use of groundwater resource is very significant in regions such as plain of Birjand. Ease of removal from groundwater sources and potential exploitation of the weak area of surface water resources is one of the main reasons for this. As a result, the protection of groundwater in these areas is very important. Integrated urban wastewater project will impact directly on aquifer of plain. Balance conceptual model of aquifer was coded in VISUAL BASIC for assessment impacts of this plan. Three level of development (A, B, C) for this plan was considered until 2020. A, B levels show develop of plan in 60, 100 percent respectively and C level shows no plane. Precipitation was extracted of output of AOGCM models under three scenarios of A1B, B1, and A2. Head simulation results shows that maximum head loss occurs by 6.8 m in B, 5.5m in A and 3.57m in the scenario of C respectively on 2020. Also these results show that head loss in B is higher than A levels. Head loss in B level is longer than 1.3m in A level.
