| How Is The Problem Of Floods Made Worse By Soil Erosion ?
A continuous process of removing the top soil layer by water, rain or wind is known as soil erosion. Soil, in the form of mud, rock and tiny particles, is replaced by ocean currents as well. Erosion is actually a natural process, but intervention of humans has made it a major problem. Normally, soil erosion is useful for our ecosystem, but excess of it creates disadvantages.Because of removal of vegetation and deforestation, the ecosystem gets damaged and there is an imbalance. |

In addition, this leads to erosion of the top layer of the soil and water sedimentation.
Natural and manmade factors together have increased the rate of soil erosion.
Two places are affected by soil erosion. The place from where the soil is removed is known as on-site, whereas the place where the soil goes is called off-site.
When the snow over the mountain melts and the flow of water streams continuously increases, the level of water also increases. When the level of water rises above the lake or river level, it gives rise to floods as the excess water breaks its boundaries and comes to land.
Once the top layer of the soil is eroded, the ground is no longer conducive to filtration of water into the ground. This top layer is lost due to deforestation or removal of vegetation. When water does not filter into the ground, it manages to find its way into ditches and streams. These then overflow and lead to floods. Also, riverbeds rise due to eroded soil being deposited in the rivers. This again is the cause of rivers breaking their banks and causing floods.
The tendency to utilize the land also makes a difference. If proper storage of water is done, excess water can also be utilized. With increase in the level, the stored water is also absorbed by the ground at the same time. The stored water can be used for agriculture as well as for drinking purpose after purification.
Therefore, it can be said that the problem of floods is made worse by soil erosion.
