✦ Synopsis
An outline of some central methodological steps in an ecometric analysis to develop load diagrams is given. This is done within the framework of an Expert system for environmental consequence analysis for natural aquatic ecosystems. Examples focus on nutrient emissions/eutrophication in coastal areas. The analysis is based on a number of fundamental concepts (effect, dose, sensitivity, area and time compatibility, ecometric analysis, load diagrams, etc.). The paper addresses questions concerning the basic set-up of the Expert system, how to establish representative empirical data for entire coastal areas for various types of substances, e.g., nutrients, and parameters expressing eutrophication (e.g., Secchi depth, chlorophyll) and internal correlations among dose and sensitivity parameters. Limitations and advantages with the ecometric approach are stressed.
