摘要

ECCES is an environmental management model designed to predict environmental impacts from a given energy production scenario in a given geographical area for a period of time. Presently ECCES contains submodels for atmospheric dispersion and deposition of pollutants, soil chemistry and uptake in selected crops. Dispersion is based on a traditional plume model and calculates dispersion of pollutants from many sources (power plants) to counties at Zealand. The soil chemistry model calculates chemical equilibrium between absorbed and soluble ions in maximum 5 soil layers. CEC is devided between a permanent and a variale cation exchange capacity. Ion uptake in crops is proportional to the equilibrium concentration in the soil water. ECCES is implemented in FORTRAN-77. Inputs are from plant, soil, and crop libraries. Output are prints or datafiles transferable to en independent plot program. Scenario calculations illustrate the capabilities of the program, and sensitivity of some important parameters.
