Per the lie of channels, drainage systems can fall into one of several categories, known as drainage patterns. These depend on the topography and geology of the land. All forms of transitions can occur between parallel, dendritic, and trellis patterns. A drainage system is described as accordant if its pattern correlates to the structure and relief of the landscape over which it flows. http://downloads.esri.com/blogs/hydro/AH2/Arc_Hydro_Tools_2_0_Overview.pdf

WebA watershed is defined as the “area of land that drains water, sediment, and dissolved materials to a common outlet at some point along a stream channel” (Dunne and Leopold, 1978). The size and structure of watersheds vary significantly due to geologic, morphologic, vegetative, soil and climatic differences.
