  2. Water quality modelling - Wikipedia

    en.wikipedia.org/wiki/Water_quality_modelling

    Due to the increase in freshwater usage among people, water quality modeling is especially relevant [3] both in a local level and global level. In order to understand and predict the changes over time in water scarcity , climate change, and the economic factor of water resources, [ 1 ] water quality models would need sufficient data by ...

  3. Normalized difference water index - Wikipedia

    en.wikipedia.org/wiki/Normalized_Difference...

    McFeeters index: If looking for water bodies or change in water level (e.g. flooding), then it is advisable to use the green and NIR spectral bands [18] or green and SWIR spectral bands. Modification of normalised difference water index (MNDWI) has been suggested for improved detection of open water by replacing NIR spectral band with SWIR. [19]

  4. Total dissolved solids - Wikipedia

    en.wikipedia.org/wiki/Total_dissolved_solids

    Bottled mineral water usually contains higher TDS levels than tap water. Total dissolved solids (TDS) is a measure of the dissolved combined content of all inorganic and organic substances present in a liquid in molecular, ionized, or micro-granular (colloidal sol) suspended form. TDS are often measured in parts per million (ppm).

  5. Freshwater environmental quality parameters - Wikipedia

    en.wikipedia.org/wiki/Freshwater_environmental...

    Freshwater environmental quality parameters are those chemical, physical and biological parameters that can be used to characterise a freshwater body. Because almost all water bodies are dynamic in their composition, the relevant quality parameters are typically expressed as a range of expected concentrations.

  6. Kling–Gupta efficiency - Wikipedia

    en.wikipedia.org/wiki/Kling–Gupta_efficiency

    The Kling–Gupta efficiency (KGE) is a goodness-of-fit indicator widely used in the hydrologic sciences for comparing simulations to observations. It was created by hydrologic scientists Harald Kling and Hoshin Vijai Gupta. [1]

  7. Level sensor - Wikipedia

    en.wikipedia.org/wiki/Level_sensor

    Hydrostatic pressure level sensors are submersible or externally mounted pressure sensors suitable for measuring the level of corrosive liquids in deep tanks or water in reservoirs. Typically, fluid level is determined by the pressure at the bottom of the fluid containment (tank or reservoir); the pressure at the bottom, adjusted for the ...

    en.wikipedia.org/wiki/Storm_Water_Management_Model

    The water quality constituents such as water quality constituents can be simulated from buildup on the subcatchments through washoff to a hydraulic network with optional first order decay and linked pollutant removal, best management practice and low-impact development (LID) [9] removal and treatment can be simulated at selected storage nodes.
