2. Universal Soil Loss Equation - Wikipedia

   en.wikipedia.org/wiki/Universal_Soil_Loss_Equation

   The Universal Soil Loss Equation (USLE) is a widely used mathematical model that describes soil erosion processes. [1]Erosion models play critical roles in soil and water resource conservation and nonpoint source pollution assessments, including: sediment load assessment and inventory, conservation planning and design for sediment control, and for the advancement of scientific understanding.

   The runoff curve number is based on the area's hydrologic soil group, land use, treatment and hydrologic condition.References, such as from USDA [1] indicate the runoff curve numbers for characteristic land cover descriptions and a hydrologic soil group.

5. Impervious surface - Wikipedia

   en.wikipedia.org/wiki/Impervious_surface

   The pavement materials seal the soil surface, eliminating rainwater infiltration and natural groundwater recharge. This can cause urban flooding . An article in the Seattle Times states that "while urban areas cover only 3 percent of the U.S., it is estimated that their runoff is the primary source of pollution in 13 percent of rivers, 18 ...

6. Distribution uniformity - Wikipedia

   en.wikipedia.org/wiki/Distribution_uniformity

   The higher the DUlq, the more uniform the coverage of the area measured. If all samples are equal, the DUlq is 1.0 or 100%. There is no universal value of DUlq for satisfactory system performance. A value of >.80 or 80% is considered above average. Distribution uniformity may be helpful as a starting point for irrigation scheduling. For example ...
