weir gauge

Surface runoff was measured by an automatic gauge and a thin triangle weir vertically installed at the outlet of the watershed. The relationships among preferential flow, infiltrated flow and surface runoff were analyzed.

在小流域出口处设置90°薄壁三角堰和水位计记录了地表径流过程，分析了优先流和渗流、地表径流之间的关系。

The discharge, precipitation and utilizable quantity of rainwater resources were measured by H-type weir and rain gauge. The results show that catching rainwater by small watershed needs less investment and makes the best use of water resources which creates favorable conditions for economic development in Taihang Mountains.

用H型量水堰和雨量计观测太行山小流域径流量、降雨量及可利用雨水资源结果表明，在太行山区实施小流域雨水集流投资少，可充分利用雨水资源，为山区经济发展创造了条件。
