  2. Drainage - Wikipedia

    en.wikipedia.org/wiki/Drainage

    Drainage options for the construction industry include: Point drainage, which intercepts water at gullies (points). Gullies connect to drainage pipes beneath the ground surface, so deep excavation is required to facilitate this system. Support for deep trenches is required in the shape of planking, strutting or shoring.

  3. Point bar - Wikipedia

    en.wikipedia.org/wiki/Point_bar

    A point bar is an area of deposition where as a cut bank is an area of erosion. Point bars are formed as the secondary flow of the stream sweeps and rolls sand, gravel and small stones laterally across the floor of the stream and up the shallow sloping floor of the point bar.

  4. Drainage basin - Wikipedia

    en.wikipedia.org/wiki/Drainage_basin

    A drainage basin is an area of land in which all flowing surface water converges to a single point, such as a river mouth, or flows into another body of water, such as a lake or ocean. A basin is separated from adjacent basins by a perimeter, the drainage divide , [ 1 ] made up of a succession of elevated features, such as ridges and hills .

  5. Watershed delineation - Wikipedia

    en.wikipedia.org/wiki/Watershed_delineation

    Watershed delineation is the process of identifying the boundary of a watershed, also referred to as a catchment, drainage basin, or river basin.It is an important step in many areas of environmental science, engineering, and management, for example to study flooding, aquatic habitat, or water pollution.

    Radial drainage pattern The radial drainage network of Dogu’a Tembien in Ethiopia. In a radial drainage system, the streams radiate outwards from a central high point. Volcanos usually have archetypal features on which this commonly develops are modest or hard domes pattern develops when streams flow in many general directions (meaning quite ...

  7. Triple divide - Wikipedia

    en.wikipedia.org/wiki/Triple_divide

    A triple divide or triple watershed is a point on Earth's surface where three drainage basins meet. A triple divide results from the intersection of two drainage divides . Triple divides range from prominent mountain peaks to minor side peaks, down to simple slope changes on a ridge which are otherwise unremarkable.

  8. Invert level - Wikipedia

    en.wikipedia.org/wiki/Invert_level

    Invert level affects flow from drainage pipes. In civil engineering, the invert level is the base interior level of a pipe, trench or tunnel; it can be considered the "floor" level. [1] The invert is an important datum for determining the functioning or flowline of a piping system.

  9. Drainage divide - Wikipedia

    en.wikipedia.org/wiki/Drainage_divide

    A triple divide is a point, often a summit, where three drainage basins meet. A valley floor divide is a low drainage divide that runs across a valley, sometimes created by deposition or stream capture. Major divides separating rivers that drain to different seas or oceans are continental divides.
