Abstract
Simulation of tidal flow in estuarine marsh area is challenging because of resistance from spatially and temporally varied vegetation. This study simulated the tidal flow in the Davis Pond Marsh area near New Orleans, Louisiana using the Delft3D-FLOW open source program. To quantify time varying roughness coefficients, five empirical equations for calculating Manning's roughness coefficient (n) were incorporated in the Delft3D-FLOW program in addition to two options offered by this program to calculate the Chezy's C coefficient. Water surface elevations (WSE) at several locations within the study area are calculated and compared with the corresponding observed data. Results showed that the equations accounting for the degree of submergence and the vegetation frontal area give the closet matches with the observed data. The vegetation frontal area for freshwater marsh grass dominated by Panicum hemitomon type ranges from 8.16 to 11.22 m<sup>-1</sup>.
