  • What is Erosion? Effects of Soil Erosion and Land Degradation

    The effects of soil erosion go beyond the loss of fertile land. It has led to increased pollution and sedimentation in streams and rivers, clogging these waterways and causing declines in fish and other species. And degraded lands are also often less able to hold onto water, which can worsen flooding.

  • Soil Erosion and Sediment Control - Maryland

    Erosion and Sediment Control. When soil is exposed to the impacts of rainfall, there is an increase in the volume and velocity of runoff. This sets off a chain reaction that results in the transport and deposition of sediment, reduced stream capacity, and ultimately increased stream scour and flooding.

  • sediment | National Geographic Society

    Sediment is solid material that is moved and deposited in a new location. Sediment can consist of rocks and minerals, as well as the remains of plants and animals. It can be as small as a grain of sand or as large as a boulder. Sediment moves from one place to another through the process of erosion.Erosion is the removal and transportation of rock or soil.
