Groundwater is deposited as a reservoir of water under earth crust from sources like rain, irrigation, lakes, ponds, rivers and other sources. The groundwater can also cause erosion by removing the soil and highly withered rocks present above the groundwater to other locations. This result in formation of caves. The groundwater erosion can be prevented by planting bushes, preserving trees both process will allow soil to be captured with the roots, hence prevents erosion. Packing down soil will increase the compaction of soil to avoid erosion. Building drains with outlet can help to control the flow of groundwater and avoids the contact of soil and rocks with water.
