Investigation of the behavior of density current released down a sloping surface in a tank
of freshwater is reported herein. The inl1uence of slope on the behavior of density
currents, head velocity and body entrainment arc experimentally investigated. The
experiments were carried out in a tilting flume with different sediments to reasonably
obtain a wide range of results, Based on the dimension analysis, dimensionless
parameters were determined. Observations and measurements revealed a variety of
phenomena depending strongly on the Richardson Number and the angle of incline. Also
the non-dimensional head velocity and non-dimensional sediment tall velocity were
being considered. A power type equation was found between head velocity and
Buoyancy flux. Based on the present study and previous investigations of other
researchers, regression equations of water entrainment were determined as functions of
Richardson number and bed slope.
