摘要：圣佩德罗河径流的时间和位置部分取决于塞拉维斯塔子流域补给的空中分布。以前的研究人员假设，子流域的补给只发生在山前，通过靠近山脉低渗透性岩石与盆地填充物之间的接触的溪流渠道渗透。然而，最近对美国西南部其他冲积盆地的研究表明，在距离山脉几公里的地方，可以通过短暂河流的沉积物进行大量的补给。本研究的目的是描述塞拉-维斯塔小流域的入渗和随后的补给的空间分布。
Abstract : The timing and location of streamflow in the San Pedro River are partially dependent on the aerial distribution of recharge in the Sierra Vista subwatershed. Previous investigators have assumed that recharge in the subwatershed occurs only along the mountain fronts by way of stream channel infiltration near the contact between the low permeability rocks of the mountains and the basin fill. Recent studies in other alluvial basins of the Southwestern United States, however, have shown that significant recharge can occur through the sediments of ephemeral-stream channels at locations several kilometers distant from the mountains. The purpose of this study was to characterize the spatial distribution of infiltration and subsequent recharge through the ephemeral-stream channels in the Sierra Vista subwatershed.
