High-resolution field data, collected during April to October of 2008–2009, were analyzed to investigate the quantitative contribution of sediment resuspension to high-turbidity events in central Lake Erie. Resuspension events were distinguished within hig ...

Reservoir sedimentation and the resulting storage losses impact reliability, efficiency, safety and thus the sustainability of the hydropower schemes. Beside traditional storage hydropower plants, also pumped-storage facilities are affected. Flexible turbi ...

Deltas are very sensitive environments and highly vulnerable to variations in water discharge and the amount of suspended sediment load provided by the delta-forming currents. Human activities in the watershed, such as building of dams and irrigation ditch ...
We report on a series of soil erosion experiments performed on the 2-m x 6-m EPFL erosion flume. Total sediment concentrations and the concentrations of seven size fractions (1000 mm) were measured during 1 ...
The term “ecosystem engineering” emerged in the 1990s and is commonly used to refer to the activities of larger organisms like beavers and trees in rivers and streams. The focus on larger organisms may be motivated by their more visible effects on the envi ...
Local scouring is a leading cause of bridge collapses. To protect bridges against local scouring, different countermeasures have been proposed and tested in the literature. In this study, the performance of collars was evaluated for scour reduction at two ...
The success of seedlings and rejuvenated woody debris growing on river bedforms depends on the resistance to uprooting by flow provided by their simple root architecture. Avena sativa and Medicago sativa seedlings were used in flume experiments as prototyp ...
In steep mountain rivers, morphological features such as large mostly immobile boulders, strongly influence flow behavior and bedload transport. Without taking into account these large immobile boulders, which are acting as macro-roughness elements, classi ...
Increasing demand for clean sources of energy have forced electricity providers to paymore attention to their hydropower assets. Silt erosion is a destructive phenomenon that may occur in hydropower plants. The power plant subjected to silt erosion require ...
