Summary

This project it trying to identify the most appropriate parameter for representing resistance due to vegetation types typically found in the Everglades.

For more information, please see the Tides and Inflows in the Mangrove Ecotone (TIME) Model Development Project Webpage.

Surface-water flow models are needed to evaluate restoration and management alternatives for the south Florida ecosystem. Model results are sensitive to expressions used to represent flow resistance due to vegetation. The project seeks to develop methods for representing flow resistance due to vegetation types typically found in the Everglades. The project also seeks an understanding of the effect of vegetation on surface-water flow and improved techniques for measuring flow velocities and water-surface slopes in wetlands.

Restoration and management decisions about the south Florida ecosystem are based in part on the results of numerical surface-water models. Model results are sensitive to the expressions used for vegetative flow resistance and to the values of the coefficients that appear in these expressions. The objectives of the project are to identify the most appropriate parameters for representing resistance due to vegetation types typically found in the Everglades, develop empirical expressions for flow resistance, and evaluate the coefficients that appear in these expressions.
