AQUATOX for Windows: A Modular Fate and Effects Model for Aquatic Ecosystems, Release 2.1. Addendum to Release 2, Technical Documentation.

摘要

Nutrients (nitrogen and phosphorus) are leading causes of water quality impairment in the Nation's rivers, lakes and estuaries. To address this problem, states need the technical resources to establish nutrient criteria, adopt them into their water quality standards, and implement them in regulatory programs. Ecosystem models such as AQUATOX that mechanistically simulate nutrient dynamics can be one tool for deriving and implementing nutrient criteria. To further assist in modeling nutrients AQUATOX has been significantly updated since EPA Release 2 was released. There have also been several enhancements related to toxicity, along with improvements to the user interface. This document is an addendum to the AQUATOX Release 2 Technical documentation (EPA-823-R-04-002, January 2004). The document describes changes in the model that distinguish Release 2.1 from Release 2.
