HYDRAULICS OF ENERGY, DISSIPATION IN STEEP, ROUGH CHANNELS

BASED ON THE PRINCIPLE OF THE MINIMUM ENERGY CONTENT IN TUMBLING FLOW, DESIGN METHODS WERE DEVELOPED FOR THE USE OF TWO-DIMENSIONAL SQUARE BARS OR ROWS OF CUBES AS AN EFFECTIVE AND ECONOMICAL MEANS FOR ENERGY DISSIPATION IN STEEP CHANNELS. CRITERIA AND EQUATIONS WERE DERIVED FROM LABORATORY TESTS IN A 2-FOOT WIDE RECTANGULAR FLUME WITH SLOPES UP TO 30%, THEN VERIFIED BY LIMITED FIELD TESTS FOR SLOPES UP TO 67%. THE RESULTS CAN ALSO BE APPLIED TO THE TRAPEZOIDAL CHANNELS WITH 45 DEGREE SIDE WALLS. /BPR/
