Erosion
Accelerated soil erosion occurs when high intensity
of rain falls on exposed soil surface. As erosion continues, rills
and gullies develop. Associated with erosion is the loss of organic
matter and nutrients concentrated on the surface soil, and the subsequent
deposition of sediments, which reduces the capacity of stream channels
to carry floodwaters.
