A graph of the runoff distribution over a given period of time. A scientific study of the properties, distribution, and effects of water on the earth's surface, in the soil and underlying rocks and in the atmosphere. The process by which water passes into the soil. Facilities intended to detain, retain, convey or otherwise provide a flood control function consistent with state and federal regulations. The science dealing with the phenomena of the atmosphere, especially weather and weather conditions. The minor drainage system indudes lateral storm sewer system and /or ditches that convey runoff to major storm water facilities. The minor system does not generally convey flow from one major facility to another. The methods of alleviating the impacts of land disturbance on wetland areas. The process by which plants use minerals and organic nutrients, changing nourishment into living tissue. The temporary storage of water on a single project area. The highest rate of outflow from a detention area or conveyance system, for a given frequency of recurrence. The process by which waters on the earth's surface infiltrate the soils to replenish the groundwater. Any area that retains all runoff to that area, that is, an area without an outlet. A retention area is referred to as a landlocked area.
