FLOW AT GRADE-BREAK FROM MILD TO STEEP SLOPES

An empirical equation was determined using dimensional analysis and experimental test data to determine the depth of flow at a grade-brake in a rectangular channel where the slope changes from mild to steep. The ratio of the depth of flow at slope of the downstream reach. The ratio reached a minimum of 0.715 when the downstream slope was steep enough to produce clear separation of the flow with an aerated nappe. The upper limit of 1.0 was approached as the downstream slope approached critical. /ASCE/
