The Gradient-Related Discharge in an Everglades Network (GARDEN) application

GARDEN was developed by the U.S. Geological Survey in cooperation with the U.S. Army Corps of Engineers to use the water-level surfaces developed by EDEN to estimate gradients and volumetric flow rates in the Greater Everglades. Flow rates in both the x and y directions are computed by using the water-level gradients provided by EDEN. The frictional resistance is estimated for a modified version of the Mannings Equation by calibrating the parameters to measured flow rates at coastal creeks fed by EDEN boundary flows. Development of GARDEN is described in Swain and Adams (2024).

The GARDEN application provides a tool that scientists and water managers can use to estimate water flows and distributions in the Greater Everglades. The daily maps of flow vectors can be downloaded as graphics or NetCDF data files. The response of the daily flow-vector map to water-management releases can be tracked spatially and temporally, providing users with volumetric information on the distribution of water in the Greater Everglades,
