Analyzing Natural Systems: Analysis for Regional Residuals-Environmental Quality Management

摘要

Approaches for analyzing natural systems for regional residuals-environmental quality management (REQM) are presented. System components include land surface runoff, surface receiving water and atmospheric systems. The report identifies and describes the principal approaches and associated analytical techniques used to analyze natural systems, provides detailed summaries of a number of operational natural systems models, indicates the factors that must be taken into account in selecting a model in a given REQM context, describes how to select an appropriate model, and shows how information on modified and new models can be incorporated systematically into an existing framework.
