Summary

This project aims to derive relationships between hydrologic conditions and mangrove ecosystem function.

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

Please note: This individual project is now completed and is now part of the "Dynamics of Land Margin Ecosystems: Historical Change, Hydrology, Vegetation, Sediment, and Climate" project.

The focus of this research is (1) quantifying groundwater and and surface-water flow dynamics within the coastal mangrove zone and within the adjacent freshwater marsh, (2) defining the response of fluid flow characteristics to changes in weather and water management practices, and (3) deriving relationships between hydrologic conditions and vegetation indices of the mangrove-marsh ecotone.

A two-dimensional finite-difference model has been constructed that accurately predicts the temporal variability in water levels in the central portion of Shark River Slough. The domain of this model is being extended to include the coastal mangrove zone, and the model is being modified to account for complications associated with the mixing of fresh and saline waters.
