Abstract

Investigation of the behaviour of density current released down a sloping surface in a tank of freshwateiis reported here. The influence of'slope on the behaviour of density currents, head velocity and body entrainment areexperimentally investigated. The experiments were carried out in a tilting flume with different sediments to reasonablyget a wide range ofresults. Based on the dimension analysis, dimensionless parameters were determined. Observationsand measurements revealed a variety of phenomena depending strongly on the Richardson Number and the angle ofincline, Also the non-dimensional head velocity and non-dimensional sediment fall velocity were being consideredPower type equations were found between head velocity and Buoyancy flux. Based on present study and previousinvestigations of other researchers, regression equations of water entrainment as functions of Richardson numbeiand slope were determined.
