小流域地表径流测量中影响三角槽测流的因素及最优三角槽

FACTORS AFFECTING MEASURING VEE GUTTER AND THE BEST VEE GUTTER DESIGN

影响三角槽测流的因素为：三角槽底坡、三角槽夹角、水流含沙量及水流中挟带砾石的小大。本文对上述因素进行了综合分析，在此基础上，提出了四种测流范围广、输沙能力强的三角槽，用于小流域径流测量。

The factors affecting the flow in vee gutter are :base slope,included angle,silt in flowand size of the gravel in water.The paper com prehensively analyzes them and gives 4types of vee gutter for flow measurement in small watershed.They all can be widespreadlyused and transport much silt.=
