STATUS: In cooperation with the University of Louisiana-Lafayette, the Arthur R. Marshall Loxahatchee National Wildlife Refuge (Refuge) is developing and applying a suite of hydrology and water quality models. The models are formulated with varying levels of spatial resolution. The water quality model with the least spatial resolution has three concentric marsh cells and a single canal cell; the highest spatial resolution model represents the marsh as 3,494 active computational cells. These models improve our quantitative understanding of mechanisms affecting timing and levels of water depth, and water quality throughout the Refuge canal and marsh. Each model has specific advantages and limitations. Professional judgment is essential in using any model. At present, a suite of four hierarchical models predicting stage (water surface elevation) and water quality are under active development and application:
