  2. Hydrological transport model - Wikipedia

    en.wikipedia.org/wiki/Hydrological_transport_model

    The DSSAM Model is constructed to allow dynamic decay of most pollutants; for example, total nitrogen and phosphorus are allowed to be consumed by benthic algae in each time step, and the algal communities are given a separate population dynamic in each river reach (e.g. based upon river temperature).

  3. Hydrological model - Wikipedia

    en.wikipedia.org/wiki/Hydrological_model

    Examples of governing equations include: Manning's equation is an algebraic equation that predicts stream velocity as a function of channel roughness, the hydraulic radius, and the channel slope: v = k n R 2 / 3 S 1 / 2 {\displaystyle v={k \over n}R^{2/3}S^{1/2}}

  4. Hjulström curve - Wikipedia

    en.wikipedia.org/wiki/Hjulström_curve

    The Hjulström curve, named after Filip Hjulström (1902–1982), is a graph used by hydrologists and geologists to determine whether a river will erode, transport, or deposit sediment. It was originally published in his doctoral thesis "Studies of the morphological activity of rivers as illustrated by the river Fyris. [1]" in 1935. The graph ...

  5. Standard step method - Wikipedia

    en.wikipedia.org/wiki/Standard_Step_Method

    A diagram showing the relationship for flow depth (y) and total Energy (E) for a given flow (Q). Note the location of critical flow, subcritical flow, and supercritical flow. The energy equation used for open channel flow computations is a simplification of the Bernoulli Equation (See Bernoulli Principle ), which takes into account pressure ...

  6. Streeter–Phelps equation - Wikipedia

    en.wikipedia.org/wiki/Streeter–Phelps_equation

    Example of a river, Tigris River near Hasankeyf, in Turkey. The Streeter–Phelps equation is used in the study of water pollution as a water quality modelling tool. The model describes how dissolved oxygen (DO) decreases in a river or stream along a certain distance by degradation of biochemical oxygen demand (BOD).

  8. Stream power - Wikipedia

    en.wikipedia.org/wiki/Stream_power

    Stream power, originally derived by R. A. Bagnold in the 1960s, is the amount of energy the water in a river or stream is exerting on the sides and bottom of the river. [1] Stream power is the result of multiplying the density of the water, the acceleration of the water due to gravity, the volume of water flowing through the river, and the ...
