Long-term sedimentation of pumped storage reservoirs due to the alternation of turbine and pumping modes is an issue regarding sustainability and reliability of such schemes. Systematic experiments on a cuboidal basin are conducted to study how flow fields ...
Shallow reservoirs are threatened by fast filling up with sediments, even if the entering sediments are only suspended loads. The sedimentation process is strongly influenced by the geometry of such shallow reservoirs. In the framework of a research projec ...
The problem of transport of suspended sediment after the break of a dam on an inclined bed is considered. To that end we use the shallow-water approximation for arbitrary, constant slopes of the bottom, taking into consideration the effect of friction. The ...
A two-dimensional two-phase flow framework for fluid- sediment flow simulation in the surf and swash zones was described. Propagation, breaking, uprush and backwash of waves on sloping beaches were studied numerically with an emphasis on fluid hydrodynamic ...
The deposition behavior of fine sediment is an important phenomenon, which remains unclear to engineers concerned about reservoir sedimentation. In the present case bed level changes, suspended sediment concentrations, and flow velocities were measured in ...

With the projected increase in world population to 9 billion by 2050, along with per capita income growth, the demand for land and water resources is going to increase significantly. Conversion of land to intensive agriculture has led to dramatic decreases ...

The worst enemy of sustainable use of reservoirs is sedimentation. Often the main silting process is the result of settling down of suspended sediments. In shallow reservoirs the flow pattern and the sediment deposition processes are strongly influenced by ...
This chapter discusses the work carried out to establish the link between climate and atmospheric composition over the last million years, a period over which archives from different media offer precious information with a high degree of detail and accurac ...

The overall dam-break phenomenon is currently well understood for reservoirs filled with water. However, many dams face serious problems of reservoir sedimentation. Thus, regarding risk management, the influence of a large amount of sediment in the reservo ...
