DMSTA Simulation Results Case: OEW Period: 07/01/88 to 08/08/03
Case: Orlando Easterly Wetlands / Iron Bridge; 1989-2003; Heterogeneous multi-cell treatment wetlands;  deep & shallow cells; emergents, hardwoods, lake; started on cow pasture (high initial P?); depth information limited; P detection limit = 20 ppb; inflow p declined from 600 to 100 ppb; experimental manipulations began in mid 1997 (southern flow path taken off line)
