WebClassic stream order [ edit] The classic stream order, also called Hack's stream order or Gravelius' stream order, is a "bottom up" hierarchy that allocates the number "1" to the river with its mouth at the sea (the main stem ). Stream order is an important aspect of a drainage basin. It is defined as the measure of the position of a stream in ... WebThe hydrology tools focus on the movement of water across a surface. A drainage basin is an area that drains water and other substances to a common outlet. Other common terms for a drainage basin are watershed, basin, catchment, or contributing area. This area is normally defined as the total area flowing to a given outlet, or pour point.
