Document Summary
Water resources: distribution of water on earth 70. 8% of earth is covered by water. River systems: fluvial environments as earth science systems fluvial is any process or landform related to streams and rivers. They are part of the surface water reservoir for the hydrologic cycle: surface runoff overland flow, rills, and gullies base flow - groundwater, base level a theoretical level below which a stream cannot erode its valley. Ultimate base level is a surface that extends inland from sea level, sloping gently upward. Longitudinal profiles local base level can be changed and affect landscapes with things such as dams: local base level can control the lower limit of local smaller streams for a region. Consists of a network of stream channels and the slopes that drain into those channels. Low drainage density: less erodible rock, permeable rocks, gentle slopes, dense vegetation.
