What are the predicted long-term transport, fate and effects?

Poster presented May 1999, at the South Florida Restoration Science Forum

Part 1: Everglades Landscape Model

The spatially explicit ELM simulates the interactions among dynamic hydrology, biology, and biogeochemistry within the wetlands

For further ELM (V. 1 & 2.0) description and results, see the Landscape Synthesis and Ecological Modeling section

ELM is designed to evaluate ecological responses to water and P management
What happens when the surface water phosphorus (P) concentration entering WCA-2A is reduced?

(Simulation periods, 1980 - 1996)

Case 1: Historical inflow P (>100 ppb) concentration		Near the inflows, there is: Less periphyton		1995		Near the inflows, there is: More cattail
Case 2: Reduced inflow P (max. = 15 ppb TP) concentration		More periphyton	Native periphyton	1995		Less cattail

ELM v.1.0 applied to WCA-2A

After 17 years of simulated P reductions, porewater P in soils near inflows was reduced by about 50% compared to the historical case.
