Unimpaired runoff refers to the natural flow of water in a river or watershed without any human-made alterations or impacts, such as dams, water diversions, or water withdrawals. It represents the volume of water that would flow through a specific point in a river system under natural conditions, taking into account only natural variables like precipitation, evaporation, and land use.
