The slope range characterized by medium surface drainage with cover typically falls between 5-14%. This range indicates an adequate gradient for water movement without causing excessive runoff or erosion, while still being steep enough to allow for the natural drainage processes to occur. Slopes within this range can support vegetation that can help stabilize the soil and facilitate better water infiltration.

When considering other slope ranges, slopes between 2-9% may be on the lower end of the medium drainage category, offering not quite the same level of drainage efficiency. The 0-5% slope range is generally indicative of flatter areas that may have poor drainage due to limited gravity-driven water movement. Slopes above 14% tend to be at risk for high erosion rates and may not retain cover well, leading to quicker surface runoff and less effective drainage. Therefore, the 5-14% slope range is ideal for supporting medium surface drainage with cover.
