Water Quality Analysis and Modeling

Hydrosphere offers a comprehensive set of water-quality services.  We have helped clients achieve a variety of water-quality objectives including environmental permitting, TMDLs, FERC re-licensing, watershed-based trading, trophic state evaluation, limiting factor analysis, and watershed management.

    Our water-quality services include:

  • Data analysis, database management and water-quality assessment
  • Design and implementation of monitoring programs
  • Mathematical modeling of surface water and groundwater systems
  • Watershed modeling and impacts to surface water bodies
  • Watershed-based trading
  • Recommendations for restoration and management options

Water quality modeling is an area of particular expertise.  We have modeled the fate and transport of a variety of water-quality constituents in natural surface waters.

    These projects have included:

  • Nutrient/food chain modeling (eutrophication modeling)
  • Modeling of temperature, toxic substances, metals, and sediment
  • Simulation of constituents in rivers, streams, lakes, and reservoirs, often using water body hydrodynamics
  • Application of QUAL2E, CE-QUAL-W2, CE-QUAL-R1, WASP5, BETTER, HEC-5Q, and WQRRS

In situations where an ‘off the shelf’ model would not meet project requirements, we have developed customized models.  Hydrosphere has also developed watershed models to support surface water-quality models by quantifying pollutant loadings from the direct drainage basin.
