Abstract

Abstract - The precision of timing devices in modern electronic data loggers makes it possible to study the routing of water through small drainage basins having rapid responses to hydrologic impulses. Storm hyetographs were measured using digital tipping bucket rain gauges and their routing was observed at headwater piezometers located mid-slope, above a swale, and near the swale. Downslope, flow was recorded from naturally occurring soil pipes draining the 0.8-ha swale. Progressing downstream from the swale, streamflow was measured at stations gauging nested basins of 16, 52, 156, 217, and 383 ha. Peak lag time significantly (p = 0.035) increased downstream. Peak unit area discharge decreased downstream, but the relationship was not statistically significant (p = 0.456)
