ABSTRACT Karst aquifers and springs are important with respect to their potential for supplying drinking water in regions suffering from water scarcity in Iran. Accordingly, it is essential to determine the recharge potential of the catchment and the regions with higher obtainability potential. This study provides a road map for the Sheshpeer catchment in southern Iran. A recharge potential (RP) map was produced from which a recharge index (RI) was computed for several selected springs in the catchment. Furthermore, the unit discharge (q) – defined as the average annual discharge for a given catchment area and unit rainfall depth for each spring – was calculated. The plot of q versus RI for the springs showed a linear positive relationship between the two variables (R 2 = 0.9). Applying the trend equation of this plot to the whole Sheshpeer karstic catchment reveals that its long-term recharge coefficient is 0.74.

引入补给-排放关系来评价岩溶含水层的补给系数：专题和索引方法

摘要 岩溶含水层和泉水对于伊朗缺水地区的饮用水供应潜力非常重要。因此，必须确定集水区和具有较高可获取潜力的地区的补给潜力。这项研究为伊朗南部的 Sheshpeer 流域提供了路线图。生成了一个补给电位 (RP) 地图，从中计算了集水区几个选定泉水的补给指数 (RI)。此外，还计算了单位流量 (q)——定义为给定集水区和每个春季单位降雨深度的平均年流量。弹簧的 q 与 RI 的关系图显示了两个变量之间的线性正相关关系 (R 2 = 0.9)。
