Water Surface Profile of Stream with Side Overflow

Abstract

Overflow depth on a levee crown is studied using one dimensional analysis of a stream with side overflow. There are two typical water surface profiles which depend only on channel properties and not on flow rate. Their approximate solutions are presented and examined in detail. Applicability of the theoretical results were verified with experimental flume data. The relationship between overflow depth and channel properties was calculated using a one dimensional momentum equation. Two important parameters concerned with a bankfull flow include the Froude number and channel
