Abstract: Change silt charge of water in the rivers can negatively be reflected in throughput the rivers beds, stability of coast, change of river structures, dis appearance of boggy places, etc. In work questions of variability silt charge waters in the river Sluch in time and on length of the river are considered. It is revealed that in time average and maximal silt charge waters decrease. While on length of the river change silt charge waters is shown... More

Abstract: Local scour is the reduction of original bed level around any hydraulic structure. Bridge failure due to scouring has made researchers study the cause of scouring and predict the scour depth and pattern around bridge piers and foundations. Several investigators have extensively studied local scour around isolated bridge pier, but modern designs of the bridges comprise of wide span and thus group of piers rather than a single pier. The flow and... More
