Discharge capacity of low head sluice

Xujin Zhang

Open publisher page 2 citations

Abstract

The discharge capacity and affecting factors of low head sluices,especially the effect of elevation difference between upstream riverbed and sluice project floor as well as the effect of submergence coefficient are studied experimentally and theoretically.The empirical formulas for calculating discharge capacity under various submergences and estimating the influence of elevation difference on discharge coefficient are deduced.The suitability and validity of the proposed formulas are verified by engineering practice.
