A TWO-DIMENSIONAL FINITE-VOLUME HYDRODYNAMIC MODEL FOR COASTAL WETLANDS

This project was initiated in 1993 for the purpose of developing hydrodynamic models of tidal flow in coastal river-marsh systems. These models can be used as an analytical framework to address the need for environmental assessment for permit applications as well as for use in the design and maintenance of highway structures for the Connecticut Department of Transportation. In the initial phase of the project, a pseudo-2D hydrodynamic model was developed. The field data collected at the Oyster River marsh site was used for the model calibration and validation. It was followed up by the development of a two-dimensional finite-volume hydrodynamic model and by an extensive field work conducted at the Menunketesuck River marsh in Westbrook, Connecticut and a wind tunnel study of the characteristics of friction drag of marsh vegetation in the laboratory. The finite-volume approach used in this model can handle the complex topographic features of coastal marshes and various discontinuity of flow caused by hydraulic structures. The model was calibrated and validated by using the observed data from the Menunketesuck River site. The model was later applied to study the tidal flushing of the Farm River marsh in East Haven, Connecticut. These models will provide an analytical tool for the highway engineer to assess the impacts of highway structures on tidal flushing.
