Watershed | The land area from which surface runoff drains into a stream, channel, lake, reservoir or other body of water; also called a drainage basin. |
Wetlands | Lands where water saturation is the dominant factor determining the nature of the soil development and the plant and animal communities (e.g., sloughs, estuaries, marshes). |
hydrology | study of water |
Groundwater | Water that infiltrates the soil and is located in underground reservoirs called aquifers. |
Mitigation | The policy of constructing or creating man-made habitats, such as wetlands, to replace those lost to development |
