  2. Flood stage - Wikipedia

    en.wikipedia.org/wiki/Flood_stage

    Flood stage is the water level, as read by a stream gauge or tide gauge, for a body of water at a particular location, measured from the level at which a body of water threatens lives, property, commerce, or travel. [1] The term "at flood stage" is commonly used to describe the point at which this occurs.

  3. Hydrograph - Wikipedia

    en.wikipedia.org/wiki/Hydrograph

    A hydrograph is a graph showing the rate of flow versus time past a specific point in a river, channel, or conduit carrying flow. The rate of flow is typically expressed in units of cubic meters per second (m³/s) or cubic feet per second (cfs). Hydrographs often relate changes of precipitation to changes in discharge over time. [1]

  4. Routing (hydrology) - Wikipedia

    en.wikipedia.org/wiki/Routing_(hydrology)

    Flood routing is a procedure to determine the time and magnitude of flow (i.e., the flow hydrograph) at a point on a watercourse from known or assumed hydrographs at one or more points upstream. The procedure is specifically known as Flood routing, if the flow is a flood. [14] [15] After Routing, the peak gets attenuated & a time lag is ...

  5. Stream gauge - Wikipedia

    en.wikipedia.org/wiki/Stream_gauge

    The first routine measurements of river flow in England began on the Thames and Lea in the 1880s, [2] and in Scotland on the River Garry in 1913. [3] The national gauging station network was established in its current form by the early 1970s and consists of approximately 1500 flow measurement stations supplemented by a variable number of temporary monitoring sites. [2]

  6. Streamflow - Wikipedia

    en.wikipedia.org/wiki/Streamflow

    The 1993 Mississippi river flood, the largest ever recorded on the river, was a response to a heavy, long duration spring and summer rainfalls. Early rains saturated the soil over more than a 300,000 square miles of the upper watershed, greatly reducing infiltration and leaving soils with little or no storage capacity.

  7. Hydrography - Wikipedia

    en.wikipedia.org/wiki/Hydrography

    Table of geography, hydrography, and navigation, from a 1728 Cyclopaedia.. Hydrography is the branch of applied sciences which deals with the measurement and description of the physical features of oceans, seas, coastal areas, lakes and rivers, as well as with the prediction of their change over time, for the primary purpose of safety of navigation and in support of all other marine activities ...

  8. River regime - Wikipedia

    en.wikipedia.org/wiki/River_regime

    refers to a "dominant discharge" or "channel-forming discharge", which is typically the 12 year flood, though there is a large amount of scatter around this mean. This is the event that causes significant erosion and deposition and determines the channel morphology.

  9. Runoff (hydrology) - Wikipedia

    en.wikipedia.org/wiki/Runoff_(hydrology)

    The diagram also shows how human water use impacts where water is stored and how it moves. [ 1 ] The water cycle (or hydrologic cycle or hydrological cycle) is a biogeochemical cycle that involves the continuous movement of water on, above and below the surface of the Earth .
