DYNTOX: Dynamic Toxics Model

DESCRIPTION

DYNTOX (Dynamic Toxics Model) is a probabilistic model to locate diffuse pollution. It may be used with continuous simulation, Monte Carlo simulation or a log normal analysis. It is mainly used for aquatic ecosystems and has a specific interface.

This tool assesses the impact of toxic discharges on receiving water quality over the entire range of historical and future conditions. DYNTOX is both a steady state and dynamic wasteload allocation (WLA) model. Historical and future conditions are analyzed to define the frequency and duration of exposure above specified limits. Simplified pre- and post-processing capabilities are being developed for DYNTOX. Additional new features of the model include partial mix factors and variable water quality criteria for metals and ammonia.
