Channel Erosion {Ans: can occur in two ways; typically you can observe vertical sides and down-cutting of the receiving channel 1. when gullies are not repaired in time and large volumes of water increase the size of the gully 2. in existing streams or drainage ways when the volume and velocity of flow destroys the structural integrity of stream beds and banks}Rill Erosion {Ans: begins when shallow sheet flow begins to concentrate in low spots; as flow changes from sheet flow to deeper flow in these low areas, the velocity and turbulence increases; the energy of this concentrated flow detaches and transports soil material, cutting tiny channels or rills that are only a few inches deep; at this stage, hand tools or other surface treatments will easily repair erosion damage (topsoil)}ESC Program Goal {Ans: "effective control of soil erosion, sediment deposition, and nonagricultural runoff...to prevent the unreasonable degradation of property, stream channels, waters, and other natural resources." (due to non-agricultural activities) protect downstream properties from - sediment deposition - damage due to increases in volume, velocity and peak flow rates or runoff}800 Hour Work Experience Form {Ans: individuals with at least 800 hours of on-the-job work
