GENERATION OF TROUGHS BY DENSITY CURRENTS

Hans Speekenbrink

Abstract


Along the northern bank of the so-called "Maasgeul" scour has occurred, causing a trough. It is concluded from field measurements that the trough development is induced by density currents along the slope of the bank. The stratified flow system is dealt with mathematically. The calculated results are compared with the field measurements and agree fairly well. Trough development can be avoided by flattening the slope or by a bottom protection.
