Kinetics Formulations for ICM-Lite: A Tool to Predict and Quantify Ecosystem Benefits in Aquatic Systems.

摘要

ICM-Lite is envisioned as a tool to rapidly predict and quantify ecosystem benefits in aquatic systems. ICM-Lite consists of three modules: a water quality module, a graphical user interface, and an ecosystems benefits module. This publication documents the formulations of the water quality module. Documentation includes the mass balance equation, kinetics in the water column, and representations of sediment-water fluxes. The mass balance relationships are intended to incorporate flows and volumes provided by the user and obtained outside of ICM-Lite. The kinetics include representations of the aquatic carbon, nitrogen, phosphorus, and oxygen cycles. Salinity, temperature, suspended solids, and one user-defined substances are included, as well. Sediment-water fluxes of organic matter, ammonium, nitrate, phosphate, and dissolved oxygen are considered.
