Application of Ecosystem Modeling Methodologies to Dredged Material Research.

摘要

The report addresses the applicability of physical and mathematical ecosystem modeling methodologies to environmental problems associated with dredging and disposal operations. Three categories of physical models are discussed: Bioassays,microcosms,and scaled ecosystem models. Mathematical models can be divided into a number of classes,such as those predicting the effect of allochthonous loadings on the dissolved oxygen budget,determining the partitioning and dynamics of chemical constituents,predicting excessive eutrophication and nuisance algal blooms due to high nutrient loadings,and simulating biological population dynamics and ecological interactions.
