Will hydropower cause soil erosion?

First of all, we need to explain two concepts

1. The water level in the reservoir area changes with the volume of water storage

So all the factors that can affect the water. storage volume can affect water level

2. The reservoir water body is not "horizontal" from a macro perspective and often has "slopes" and "curved surfaces"

This seems like a very simple truth, why ? What about the water level?

If the tank backfill is repeatedly soaked with water, the part that absorbs the most water will become deformed. If the deformation is excessive, it will be “disconnected” from the part that absorbs relatively little water and collapse. occur

I want to prove the collapse of the reservoir dike myself. How do I proceed ?

EmpPlace the flour on a flat, non-absorbent volcano-shaped plate, then scoop out the middle and fill it with water

The last step is to use a chopstick to stir it. in the "tank" Stir it

Wait to see the results

Hydroelectric power generation does not release much cooling water. This will not cause an increase in water temperature downstream at all. If you think about it, a huge amount of water arrives upstream of the hydroelectric plant. The hydroelectric generator only uses part of the energy to do its job without consuming water. The cooling water volume of the individual components is very small compared to the total. the flow of water, it is therefore completely impossible to increase the temperature of the water downstream behind the dam. It doesn't consume much energy.
