Abstract

The first step of aquifer parameter and dependent variable estimation based on hydraulic modeling is generally to choose the best steady-state condition for the set time period. In order to define the best estimated hydraulic conductiv- ity and boundary condition for Gareh-Bygone Plain in arid southern Iran, ten different steady-state conditions were simulated and calibrated with limited field observations. The investigated area covers about 6000 ha with a floodwater spreading system that was established on about 2000 ha to artificially recharge the groundwater. The results showed a consistency over the 14-year simulation period with estimated hydraulic conductivity in a quite narrow range. This makes us believe that even if the modeling problem is to some extent over-parameterized the results appear quite robust. This is further strengthened by verification of the model results. Furthermore, the results showed that in the steady-state groundwater flow with no recharge from surface water, the system is mainly recharged by the fault which conducts water into the area from an upper sub-basin.
伊朗Gareh-Bygone平原稳态无承压含水层模拟:稳态无承压含水层模拟
基于水力模型的含水层参数及因变量估计的第一步一般是选择设定时间段内的最佳稳态条件。为了确定伊朗南部干旱地区Gareh-Bygone平原的最佳水力导电性和边界条件,利用有限的现场观测对10种不同的稳态条件进行了模拟和校准。调查区占地约6000公顷,并在约2000公顷的土地上建立了一个洪水扩散系统,以人工补充地下水。结果表明,在14年的模拟期间,估计的水力传导率在相当窄的范围内是一致的。这使我们相信,即使建模问题在某种程度上过度参数化,结果也显得相当稳健。模型结果的验证进一步强化了这一点。结果表明,在不受地表水补给的稳态地下水流动中,系统主要由断层从上次盆地引水进入。
