Abstract:

Rapid disappearance and deterioration of wetlands as a consequence of increasing human utilization coupled with growing recognition by the scientific community of the ecological importance of these areas indicate the need to investigate ecologically sound alternatives for using dredged material. Three parallel studies were conducted with the development of a simulation model of plant growth and succession on a salt marsh being the ultimate objective. A model was developed which depicted plant growth and succession across a transect. The model was driven by solar radiation, temperature, soil, salinity, and tidal inundation. The model showed plant growth controlled primarily by tidal inundation, with influences felt from radiation and temperature, but little influence due to salinity. The model appears to have great utility for future use but presently is limited in application by incomplete parameterizations.
