SMPTOX3 model / documentation

U.S. EPA regulatory programs have sponsored development of an interactive computer program for performing waste load allocations for toxics -- Simplified Method Program - Variable Complexity Stream Toxics Model (SMPTOX3). SMPTOX3 provides user-friendly access to a technique for calculating water column and stream bed toxic substance concentrations resulting from point source discharges into streams and rivers. It predicts pollutant concentrations in dissolved and particulate phases for water column and bed sediments and total suspended solid. SMPTOX3 provides a user-friendly microcomputer program for performing toxics modeling. It contains a full screen editor to facilitate the entry and modification of inputs. Separate simulation routines are provided for model calibration, waste load allocation, and sensitivity analysis. Each routine provides high resolution graphics of model results during program operation. Inputs and results can also be routed to a printer.
