Erosive wear of hydro turbine runners is a complex phenomenon, which depends upon
different parameters such as silt size, hardness and concentration, velocity of water, and …

The flow of sediment particles in rivers is a big challenge to develop hydropower plants
across the sediment-laden rivers. Hard particles such as quartz and feldspar are available in …

We evaluate changes to subglacial sediment discharge during glacier retreat by considering
ice dynamics, bedrock erosion, and sediment transport processes. Coupling these …

Kaplan turbines, as one of the well-known hydraulic turbines, are generally utilized
worldwide for low-head and high-flow conditions. Any failure in each of the turbine …

This paper provides an overview of a 100 year history of hydropower in Nepal. The
importance of hydropower in Nepal is highlighted and major issues that the country has to …

Sediment in the flowing water are normally considered an obstacle for hydropower plants
(HPPs). The operation and management of HPPs have been a significant challenge in …

Sediment particles passing through the turbine components erode the surface in contact.
Gradual removal of base material changes the runner profile and also weakens its structure …

One of the factors contributing to the gradual decline in the performance as well as the
failure of hydropower plants over the years is silt erosion. Several researchers have …

Climate change may affect sediment fluvial export from high mountain regions, leading to
downstream environmental disruptions and direct impacts on human activities. In this paper …

Sediment erosion of Pelton turbines seriously damage the economic benefits and safe
operation of the power station under the high head. The gas-liquid-solid three-phase …
