Across Trophic Level System Simulation (ATLSS) - Hydrology
One of the key features of the ATLSS models is the use of a high resolution hydrology model based on vegetation maps to convert the low resolution hydrologic output of the South Florida Water Management Model (1 water value per 2 x 2 mile cell) to the higher resolution needed to model ecological processes and the distribution of wildlife species. The ATLSS High Resolution Hydrology Model post-processes the output of the South Florida Water Management Model (WMM) using an algorithm based on conservation of water volume, and redistributes the water volume over a surface of high resolution topography (ATLSS 'pseudotopography') to produce a high resolution map of water depth. This process is repeated on daily timesteps (corresponding to the daily output of the WMM) to create a map of water depth across the wetlands of South Florida with over 3000 separate values within each 2 x 2 mile cell (using topography based on the 28.5 meter resolution of a LandSat image).
