Erosion is a serious problem for productive agricultural land and for water quality concerns. Water finds a path to escape the flat land, eventually the surface soil erodes due to the quick movement of water.
The impact of soil erosion on water quality becomes significant, particularly as soil surface runoff. Sediment production and soil erosion are closely related.
Soil erosion by water occurs when bare-sloped soil surface is exposed to rainfall, and the rainfall intensity exceeds the rate of soil intake, or infiltration rate, leading to soil-surface runoff.
I have been keeping watch of this silo foundation from years ago. The land, once a farm is now a park. This creek has been slowly moving, and has now claimed the foundation as part of the creek.
Water is so powerful and when finding ways to escape it will cut back the land. This farmer filled the cut back with large stones to help with the erosion, then the horizontal gate acts as a dam to slow the water and create a back-up. This alleviates the powerful water eating away at the land. When these issues are not addressed, new water ways are formed.
