  2. 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.

  3. Groundwater sapping - Wikipedia

    en.wikipedia.org/wiki/Groundwater_sapping

    The consistent flow of water displaces fine sediments which physically and chemically weathers rocks. [1] Valleys that appear to have been created by groundwater sapping occur throughout the world in areas such as England , Colorado , Hawai’i , New Zealand , and many other places. [ 2 ]

  4. Catchment hydrology - Wikipedia

    en.wikipedia.org/wiki/Catchment_hydrology

    The surrounding topography of a catchment zone influences the flow vectors and direction that the water flows. [1] Water flows from areas of high potential energy to low potential energy under the influence of gravity. The geometry of the slope leading to the catchment area influences the amount of water the catchment will contain. [1]

  5. Groundwater recharge - Wikipedia

    en.wikipedia.org/wiki/Groundwater_recharge

    Water balance. Groundwater recharge or deep drainage or deep percolation is a hydrologic process, where water moves downward from surface water to groundwater. Recharge is the primary method through which water enters an aquifer. This process usually occurs in the vadose zone below plant roots and is often expressed as a flux to the water table ...

  6. Drainage basin - Wikipedia

    en.wikipedia.org/wiki/Drainage_basin

    The process of finding a drainage boundary is referred to as watershed delineation. Finding the area and extent of a drainage basin is an important step in many areas of science and engineering. Most of the water that discharges from the basin outlet originated as precipitation falling on the basin. [11]

    The Colorado River Upper Basin, comprised of Colorado, Wyoming, Utah and New Mexico, and the Lower Basin, made up of California, Arizona and Nevada, have been quarreling for months over seemingly ...

  8. Hydrograph - Wikipedia

    en.wikipedia.org/wiki/Hydrograph

    A stream hydrograph is commonly determining the influence of different hydrologic processes on discharge from the subject catchment. Because the timing, magnitude, and duration of groundwater return flow differs so greatly from that of direct runoff, separating and understanding the influence of these distinct processes is key to analyzing and simulating the likely hydrologic effects of ...
