提出一种平底侧收缩堰作为灌溉渠中的新型量水堰，以代替通用的薄壁堰，并对这种堰的水流特征进行了分析与初步的试验研究。这种堰的特点是构造简单，水位落差小，可在多沙渠槽中应用，而不会在堰前产生泥沙淤积。
A flat bottom shrinkage weir is proposed as a new type of weir in irrigation canals to replace the common thin-walled weir. The characteristics of water flow in this weir are analyzed and preliminary experimental studies are carried out. This type of weir is characterized by its simple structure and small drop in water level, which can be used in multi-channel channels without sedimentation in front of the weir.
