Modeling Salt Marshes and Estuaries: Progress and Problems

  • Richard G. Wiegert
Part of the Marine Science book series (MR, volume 11)


Explanatory models of salt marshes must be based on realistic interactions between structure (niches and flow pathways) and function (species and their ecological attributes). These interactions produce behavior (changes in rates and standing stocks of energy and nutrients). Such models may be used for (1) management, (2) prediction of perturbations or (3) development of testable hypotheses. Difficulties facing modelers involve (a) conserved flows, (b) trophic condensation, (c) time delays and (d) feedback controls. In addition hydrodynamic problems are important involving (e) sediment water exchanges, (f) matter/energy transport by tides, (g) catastrophic storms and tides and (h) spatial heterogeneity. Construction and use of a carbon flow model of a coastal Georgia salt marsh are discussed.
