Evaluation of Phosphorus Loading Models for South Florida

Phosphorus enrichment poses a threat to the ecology of Floridas Lake Okeechobee. As a part of a phosphorus management program, the South Florida Water Management District evaluated two nutrient loading modelsCREAMS-WT and FHANTM. Model documentation and algorithms were reviewed. Model simulations for phosphorus loading were compared to measured data for three sites for the period April 1989, through December 1991. Statistical correlation of monthly and annual values was analyzed. Based on these analyses, recommendations concerning the models for predicting phosphorus loading from Lake Okeechobee watersheds are presented.
