摘要

本文把沙波推移率公式g_s=αγ‘h_sw_s改进为g_s=0.56γ'A/Δt,使沙波推移率计算更为简便和精确。提出在单宽流量一致时，沙波上游波面推移率分布可用g_s=φγ'A/Δt来表达。对上述公式的验证和应用及推移率计算等方面皆作了论述。

Abstract

The formula currently used for calculating the bed load rate of sand wave is gs=αγ'hsws. The average volume factor we have measured in the natural river courses appr-oximates to 0.56.

Key words： Sand wave; Sand wave height; Sand wave velocity; Bed load rate
