Marsh and Coral Hydrodynamics
Marsh platform features such as rills and cuts through channel berms contribute to the control of flow patterns and the draining and filling. These small features are often missing in the model due to both incomplete resolution of the features in data sources and model grids. Loss of resolution and representation of these features can lead to modeling defects such as artificial ponding. Recently, we have introduced a porosity parameter in the FVCOM model to improve the wetting and drying in artificially isolated depressions. The paper will discuss verification of the approach in comparison to an extensive set of measurements.
