Erosion affects waterways.

Explanation:

Erosion affects waterways. If erosion is high, eroded particles deposit in river beds or available banks. Therefore, when there is a flood in such places lots of places will be under water.

Erosion also cause river ships unoperability. They are designed to navigate under regular circumstances (canal bed depth and width, for instance). If erosion deposits solid particles and cause a change in canal shape, canal depth will be lower not allowing river ships to nativate.

It contaminates it with silt and accumulated chemical residues.

Explanation:

"Normal" erosion is part of the natural rock cycle. Rivers and lakes constantly change due to the impact of silt transport. However, excessive erosion can completely alter the course and vitality of a river or stream.

Excessive siltation may destroy the habitats for some fish species, change the course and speed of a river, and introduce significant pollutants from ground runoff.
