山西省文峪河灌区,为了配合灌区內群众水利化运动的发展,使設計技术为一般基层水利干部所掌握,最近編制了一套小型灌排渠道設計及桥涵閘寬和跌水消能建筑物水力計算曲线表,对工作很方便。这套曲线表是根据文峪河灌区具体条件編制的,共分12組,郎:1. 灌溉面积与流量关系曲线表;2. 退水面积 In order to tie in with the development of mass water conservancy movement in irrigation areas and to make the design technology available to ordinary grassroots water conservancy cadres, a set of small irrigation and drainage channel design and wide and drop energy dissipation structures for bridge and culvert gates have recently been developed Hydraulic calculation curve table, the work is very convenient. This set of curves is compiled according to the specific conditions of Wenyu River Irrigation District, is divided into 12 groups, Lang: 1. Irrigation area and flow curve table; 2. Backwater area
