在基岩上覆有较薄土壤地幔的山坡上，地下水补给的空间格局鲜为人知。水在土壤中的垂直渗流、土与基岩之间的渗透性差异以及水的横向再分布之间的复杂相互作用导致了水进入基岩的空间变异性很大。在这里，我们将帕诺拉山实验坡面土壤地幔和基岩饱和导水率的新测量与以前收集的(次)地表地形和土壤深度数据相结合，以量化影响基岩地下水补给空间格局的因素。
The spatial patterns of groundwater recharge on hillslopes with a thin soil mantle overlying bedrock are poorly known. Complex interactions between vertical percolation of water through the soil, permeability contrasts between soil and bedrock and lateral redistribution of water result in large spatial variability of water moving into the bedrock. Here, we combine new measurements of saturated hydraulic conductivity of soil mantle and bedrock of the well‐studied Panola Mountain experimental hillslope with previously collected (sub)surface topography and soil depth data to quantify the factors affecting the spatial pattern of bedrock groundwater recharge.
