Document Summary
Drainage basins aka watershed: ridges form drainage divides define the water receiving area sepeartes the basin from other basins, sheet flow a thinfilm in which water initially moves downslope aka overland flow. Interfluve high ground that separates one valley from another and directs sheetflow: surface water concentrates in gills then gullies, drainage basin system small rills and gullies main tributaries & stream trunk. Energy and materials redistributed as stream adjusts to landscape outputs water and sediment disperse though the mouth of the river into another waterbody. Internal drainage water doesn"t reach another water body but drains internally through evaporation or subsurface gravitational flow. Great basin of the western united states or dead sea in middle east have no outlet to the ocean. Water above base level = energy flows down = converts to kinetic energy. Exotic streams: usually in river basins in humid climate discharge increases donwnstream.
