Erosion of material surface due to collision of solid particles has been a challenge to several
fields of engineering. Despite of centuries of investigations and research, the exact …

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 …

The Wenchuan earthquake greatly reduced the forest water conservation capacity along the
banks of Minjiang River. With the intensified soil erosion and the rapid increasing sediment …

Erosive wear has been a serious concern in mainly run-of-the-river medium and small
Francis turbines from both economic and technical perspectives. With the aim of finding …

Sediment erosion of the hydropower turbine components is one of the key challenges due to
