Experimental and numerical analysis of the scouring effects of flushing waves on sediment deposits

摘要: Abstract In the management of urban drainage networks, great interest has been recently addressed to removal sediment deposits from sewer collectors. particular, cleansing can be carried out by flushing devices able discharge a volume water during short period time. this paper an experimental and numerical investigation on scouring effects waves is presented. Experiments were laboratory channel adopting simple device considering different conditions. Accurate measurements evolution mobile-bed transported operations out. Subsequently, model was specifically developed for analysis wave propagation description channels. The based semi-coupled solution complete De Saint Venant equations flow Exner equation continuity. Numerical results compared with in order derive indications processes consequent operations.
