Document Summary
Underground depth at which the ground is totally saturated with water. Moves along land surface as run off: portion of precipitation that runs off the surface as opposed to soaking into the ground. Run off can be over land flow, it reaches a river or stream, it may be stored in lakes or ponds. Its magnitude depends on precipitation rates, duration of storm events, spatial distribution of storms: run off as inter flow. Steeper gradient = greater velocity: upstream towards the head and downstream towards the mouth, types of river, effluent/ gaining river. Located above ground level and connects to water table ( like a pool) which increases its charge. Usually found in wet climates: influent / losing rivers. Loose water by being directly connected to water table with river bed above it. Loose water by being disconnected: river discharge. Discharge (q) = cross-section area (a) x stream velocity (v)
