Erosion control is a field of study and practice that focuses on preventing or minimizing the erosion of soil and sediment on land surfaces. This erosion can be caused by various factors such as water, wind, or human activities. Erosion control techniques include the use of vegetation, erosion control blankets, bioengineering, terracing, and retaining walls to stabilize soil and prevent erosion. This area of research is important for protecting valuable agricultural land, preventing sediment pollution in water bodies, and maintaining the stability of landscapes.
