    en.wikipedia.org/wiki/Drainage_basin

    Drainage basin of the Ohio River, part of the Mississippi River drainage basin. In hydrology, the drainage basin is a logical unit of focus [clarification needed] for studying the movement of water within the hydrological cycle. The process of finding a drainage boundary is referred to as watershed delineation. Finding the area and extent of a ...

    Dendritic drainage: the Yarlung Tsangpo River, Tibet, seen from space: snow cover has melted in the valley system. In geomorphology, drainage systems, also known as river systems, are the patterns formed by the streams, rivers, and lakes in a particular drainage basin.

  6. Watershed (image processing) - Wikipedia

    en.wikipedia.org/wiki/Watershed_(image_processing)

    The name refers metaphorically to a geological watershed, or drainage divide, which separates adjacent drainage basins. The watershed transformation treats the image it operates upon like a topographic map , with the brightness of each point representing its height, and finds the lines that run along the tops of ridges.

  7. Runoff model (reservoir) - Wikipedia

    en.wikipedia.org/wiki/Runoff_model_(reservoir)

    A watershed or drainage basin. A runoff models or rainfall-runoff model describes how rainfall is converted into runoff in a drainage basin (catchment area or watershed). More precisely, it produces a surface runoff hydrograph in response to a rainfall event, represented by and input as a hyetograph.

  9. Stream order - Wikipedia

    en.wikipedia.org/wiki/Stream_order

    Stream order is an important aspect of a drainage basin. It is defined as the measure of the position of a stream in the hierarchy of streams. Tributaries are given a number one greater than that of the river or stream into which they discharge. So, for example, all immediate tributaries of the main stem are given the number "2".
