The Czech landscape has undergone various changes over the last 100 years and been mainly adapted agriculturally for economic purposes. This resulted, among other things, in reservoirs being clogged with sediment. Vrchlice Reservoir was built 1970 to supply drinking water around 50,000 inhabitants, increased sedimentation detected reservoir recent years. Water erosion sediment transport were mo...

In central Mississippi, outplanted water tupelo seedlings survived and grew well after shallow flooding (up to 8 cm) from late February through June 1. Submersion of the seedlings, flooding until late in the growing season, reflooding, and moderate siltation reduced growth. Flooding caused changes in certain soil properties, but these changes did not seem to be the major cause of growth reducti...

This paper analyzes the influence on diversion capacity of Yellow River sluices factors such as water level change in irrigation areas lower River, scouring river channels and siltation channels. It is suggested that main reason for decrease different inflow levels obvious same discharge due to continuous At end this paper, targeted countermeasures suggestions are put forward solve problem decl...
