Groundwater of Humid Tropical Hillslope

In forest site, with comparatively steeper topography and a shallower soil layer, GW at the foot of the slope was responsive to rainfall due to the rapid subsurface flow from uphill. At the oil palm site, with comparatively gentle topography and a deeper soil layer, a different GW pattern responded more slowly to rainfall在地形相对陡峭、土层较薄的森林样地中，坡脚地下水（Groundwater, GW）对降雨的响应更为迅捷，其诱因是来自上坡区域的快速地下径流。而在地形相对平缓、土层较厚的油棕种植园样地中，地下水动态模式对降雨的响应则更为迟缓。
