  2. Standard step method - Wikipedia

    en.wikipedia.org/wiki/Standard_Step_Method

    In this case, hydrostatic relationships developed for uniform flow still apply. Examples of this include the backwater behind an in-stream structure (e.g. dam, sluice gate, weir, etc.), when there is a constriction in the channel, and when there is a minor change in channel slope.

  3. Open channel spillway - Wikipedia

    en.wikipedia.org/wiki/Open_channel_spillway

    Open channel spillways are dam spillways that utilize the principles of open-channel flow to convey impounded water in order to prevent dam failure. They can function as principal spillways, emergency spillways, or both. They can be located on the dam itself or on a natural grade in the vicinity of the dam.

  4. Tmcft - Wikipedia

    en.wikipedia.org/wiki/Tmcft

    Mettur Dam capacity: 93.4 Tmcft Tmcft , ( Tmc ft ), ( TMC ), ( tmc ) is the abbreviation of thousand million cubic feet (1,000,000,000 = 10 9 = 1 billion ), commonly used in India in reference to volume of water in a reservoir [ 1 ] or river flow.

  5. Drainage density - Wikipedia

    en.wikipedia.org/wiki/Drainage_density

    Ignoring ephemeral streams in the calculations does not consider the behavior of the basin during flood events and is therefore not completely representative of the drainage characteristics of the basin. Drainage density is indicative of infiltration and permeability of a drainage basin, as well as relating to the shape of the hydrograph.

  6. Volumetric flow rate - Wikipedia

    en.wikipedia.org/wiki/Volumetric_flow_rate

    The area required to calculate the volumetric flow rate is real or imaginary, flat or curved, either as a cross-sectional area or a surface. The vector area is a combination of the magnitude of the area through which the volume passes through, A , and a unit vector normal to the area, n ^ {\displaystyle {\hat {\mathbf {n} }}} .

  7. Hurst exponent - Wikipedia

    en.wikipedia.org/wiki/Hurst_exponent

    The Hurst exponent, H, is defined in terms of the asymptotic behaviour of the rescaled range as a function of the time span of a time series as follows; [6] [7] [() ()] =, where

  8. Damköhler numbers - Wikipedia

    en.wikipedia.org/wiki/Damköhler_numbers

    Since the reaction rate determines the reaction timescale, the exact formula for the Damköhler number varies according to the rate law equation. For a general chemical reaction A → B following the Power law kinetics of n-th order, the Damköhler number for a convective flow system is defined as:

  9. Groundwater flow equation - Wikipedia

    en.wikipedia.org/wiki/Groundwater_flow_equation

    Used in hydrogeology, the groundwater flow equation is the mathematical relationship which is used to describe the flow of groundwater through an aquifer.The transient flow of groundwater is described by a form of the diffusion equation, similar to that used in heat transfer to describe the flow of heat in a solid (heat conduction).
