A method is described to estimate the distribution of ground water recharge within hydrographic basins in the Great Basin region of the southwestern United States on the basis of estimated runoff from high mountainous areas and subsequent infiltration in alluvial fans surrounding the intermontane basins. The procedure involves a combination of Geographic Information System (GIS) analysis, empirical surface-runoff modeling, and water-balance calculations. The method addresses the need to develop and incorporate constraints on the distribution of recharge in regional-scale ground water flow modeling of arid and semiarid environments. The conceptual approach and methodology were developed for Crescent Valley, Nevada. However, the concept and method are generally applicable to any region where excess precipitation in upland areas is conveyed to lower elevations before it infiltrates to recharge the ground water system. Application of the procedure to a ground water flow model of Crescent Valley appears both qualitatively and quantitatively to result in a more accurate representation of actual recharge conditions than might otherwise have been prescribed.
本文描述了一种方法,该方法基于美国西南部大盆地地区高山区域的径流估算以及山间盆地周围冲积扇的后续入渗情况,来估算该地区水文流域内的地下水补给分布。该程序涉及地理信息系统(GIS)分析、经验地表径流建模和水平衡计算的结合。该方法满足了在干旱和半干旱环境的区域尺度地下水流动建模中,对补给分布制定并纳入约束条件的需求。该概念方法和方法论是针对内华达州的新月谷开发的。然而,该概念和方法通常适用于任何高地地区多余降水在渗入补给地下水系统之前就被输送到较低海拔地区的区域。将该程序应用于新月谷的地下水流模型,在定性和定量方面似乎都比其他可能规定的情况更能准确地反映实际补给情况。
