  2. Land surface models (climate) - Wikipedia

    en.wikipedia.org/wiki/Land_surface_models_(climate)

    It has been suggested that "terrestrial biosphere models" (TBMs) is a more inclusive term than land surface models (LSMs). [4] The representation of roots in TBMs (or LSMs), however, remains relatively crude. Particularly, the dynamic functions of roots and phylogenetic basis of water uptake remain largely absent [5] [6] in LSMs.

  3. WEAP - Wikipedia

    en.wikipedia.org/wiki/Weap

    WEAP links to the USGS MODFLOW groundwater flow model and the US EPA QUAL2K surface water quality model. WEAP was created in 1988 and continues to be developed and supported by the U.S. Center of the Stockholm Environment Institute , a non-profit research institute based at Tufts University in Somerville , Massachusetts.

  4. Bresle method - Wikipedia

    en.wikipedia.org/wiki/Bresle_method

    The solubility in water depends on the type of salt. Sodium chloride can be dissolved in cold water to a concentration of 357 g∙l −1. Not only solubility differs between salts but also the conductivity. When performing a Bresle method test, not only sodium chloride is dissolved but also all other salts present on the surface.

  5. Water testing - Wikipedia

    en.wikipedia.org/wiki/Water_testing

    Water testing being conducted at a treatment facility in Broken Bow, Oklahoma. Water testing is a broad description for various procedures used to analyze water quality. Millions of water quality tests are carried out daily to fulfill regulatory requirements and to maintain safety. [1] Testing may be performed to evaluate:

  6. Water quality modelling - Wikipedia

    en.wikipedia.org/wiki/Water_quality_modelling

    A typical water quality model consists of a collection of formulations representing physical mechanisms that determine position and momentum of pollutants in a water body. [4] Models are available for individual components of the hydrological system such as surface runoff ; [ 5 ] there also exist basin wide models addressing hydrologic ...

  7. Groundwater model - Wikipedia

    en.wikipedia.org/wiki/Groundwater_model

    An example of a non-discretized radial model is the description of groundwater flow moving radially towards a deep well in a network of wells from which water is abstracted. [7] The radial flow passes through a vertical, cylindrical, cross-section representing the hydraulic equipotential of which the surface diminishes in the direction of the ...

  8. Analysis of water chemistry - Wikipedia

    en.wikipedia.org/wiki/Analysis_of_water_chemistry

    Water chemistry analysis is often the groundwork of studies of water quality, pollution, hydrology and geothermal waters. Analytical methods routinely used can detect and measure all the natural elements and their inorganic compounds and a very wide range of organic chemical species using methods such as gas chromatography and mass spectrometry .

  9. EPANET - Wikipedia

    en.wikipedia.org/wiki/EPANET

    EPANET (Environmental Protection Agency Network Evaluation Tool) is a public domain, water distribution system modeling software package developed by the United States Environmental Protection Agency's (EPA) Water Supply and Water Resources Division.
