  1. Water catchments - Science Learning Hub

    A water catchment is an area of land and the water that collects and moves through it. A catchment is often bordered by hills or mountains. The water enters via precipitation (rain or snow) and then moves across the surface or subsurface (as groundwater) until it …

  2. Water Catchment Areas (Watersheds) | Hill Country Alliance

    A water catchment (commonly referred to as a “watershed”) is an area of land where all water flows to a single stream, river, lake or even ocean. Natural boundaries of water catchments can be very small for a single creek or stream or quite large—the Colorado River basin for example.

  3. What Is a Catchment Area of a River or Lake? - WorldAtlas

    2018年6月28日 · Catchment areas are locations in low lying regions in which water from higher areas collect into a single water body. The sources of water collected can vary from rainwater to melted snow. Catchment areas may drain their water into other lower lying basins or into a single place, usually a lake, in the case of a closed catchment.

  4. What is a watershed? - NOAA's National Ocean Service

    The size of a watershed (also called a drainage basin or catchment) is defined on several scales—referred to as its Hydrologic Unit Codes (HUC)—based on the geography that is most relevant to its specific area. A watershed can be small, such …

  5. Drainage basin - Wikipedia

    Catchment factors are: topography, shape, size, soil type, and land use (paved or roofed areas). Catchment topography and shape determine the time taken for rain to reach the river, while catchment size, soil type, and development determine the amount of water to reach the river.

  6. Catchment Area Calculator

    2024年11月5日 · To calculate the catchment area for your property, you will need to determine the volume of water collected during a rainfall event and the total depth of that rainfall. By using the formula provided, you can easily estimate the catchment area.

  7. Catchment hydrology - Wikipedia

    Catchment hydrology is the study of hydrology in drainage basins. Catchments are areas of land where runoff collects to a specific zone. This movement is caused by water moving from areas of high energy to low energy due to the influence of gravity.

    2020年3月12日 · A water catchment is an area of land and the water that collects and moves through it. A catchment is often bordered by hills or mountains. The water enters via precipitation (rain or snow) and ...

  9. Catchment Area: Slope and Its Classification | Geography

    Catchment area may be defined as the area from which the surface runoff is derived. It is also known as watershed area, drainage area, drainage basin or simply basin or catchment. The unit for the catchment area is km 2 .

  10. 4.2: Catchment Area - Engineering LibreTexts

    The catchment area is the area which intercepts the rain. Knowing the catchment area is the first step in calculating the volume of water that can be caught from rainfall. A flat roof is a great example of a catchment area.
