Nowadays, the reservoir is affected strongly by the sedimentation due to the soil erosion which results mainly due to land degradation in the watershed (Chakrapani and Subramanian 1990, 1993; Mukherjee et al. 2007). These hamper the serviceability of the reservoir to a great extent. So far, there are no reported literature about the erosion ...

What is Erosion? Effects of Soil Erosion and Land Degradation
These are very real and at times severe issues. The effects of soil erosion go beyond the loss of fertile land. It has led to increased pollution and sedimentation in streams and rivers, clogging these waterways and causing declines in fish and other species. And degraded lands are also often less able to hold onto water, which can worsen flooding.

Weathering and erosion (article) | Khan Academy
There are two main types of weathering: mechanical and chemical. Mechanical weathering is the creation of sediment through physical means. For example, a stream can dislodge soil particles from its banks. Chemical weathering is the creation of sediment through chemical means. For example, acid rain can react with rocks, dissolving them.

Soil Erosion and Sedimentation
When excess soil drops out of the water and remains in the stream, the process is known as sedimentation. Naturally occurring factors also influence both the rate and the amount of erosion and deposition into streams. 1) Vegetation is the most important physical factor influencing soil erosion. A good vegetative cover binds the soil together ...

Soil Erosion: The Main Types, Causes, And Control Measures
What Is Soil Erosion And How Is It Working? Erosion of soil is a deterioration of land due to the removal of its particles. It consists of three basic stages: dislodgement, transportation, and sedimentation.Their speed depends on the soil type, aggregation, infiltration, and ground cover.For example, well-aggregated fields are less …
