culvert inlet

Based on water inlet ( outlet) layout of lock rilling and emptying culvert in mountain or hill rivers, relations between area ratio and resistance factor of some typical inlet ( outlet) layouts are studied and the design criteria are proposed.

根据山区、丘陵地区船闸输水廊道进（出）口的布置型式，研究了几种典型布置进（出）口面积比与阻力系数关系，提出了有关设计原则。
