Modeling mobility and effects of contaminants in wetlands

摘要: Early efforts at modeling wetland ecosystems were aimed primarily reflecting biomass or nutrient dynamics. A number of models have been developed for different types, including coastal salt marshes, mangrove wetlands, freshwater swamps, and riparian wetlands. The early ecosystem mostly simple compartment with linear, constant-coefficient differential equations used to simulate Practically no contaminant flux was incorporated into these models. With few exceptions, the considered spatially homogeneous. At same time that being developed, considerable effort given various processes, such as circulation sediment transport. Other process-level included plant animal uptake elimination both organic chemicals heavy metals. level detail in process models, however, has not applied most There a recent trend, increase complexity ecosystem-level incorporate spatial These developments should greatly enhance ability transport effects
