DRBC develops and applies various near-field and far-field models for basin waters. Key outputs from applications of models include the following:

  • Acute mixing zone/dilution factor determinations;
  • Heat dissipation area determinations;
  • TDS mixing zone determinations;
  • Assimilative capacity determinations for a water quality parameter of concern;
  • TMDL development to support basin states and U.S. EPA; or 
  • No Measurable Change (NMC) evaluations for dischargers in Special Protection Waters
