Systems Models for Understanding Eutrophication in Lake Okeechobee.

Abstract:
Systems models were developed to investigate ecological changes and eutrophication trends in Lake Okeechobee, Florida. An energy flow model was used to organize data and concepts on the lake as a system. Simplified models of water budget, phosphorus budget, metabolism, and water currents were simulated to estimate the effects of changes in river flow, water levels, and nutrient loads. Simulations of water budgets from 1951-1974 predicted lake stage within 10%. River basin channelization accelerated runoff into the lake with less water remaining on the land for use and discharge during dry season. Simulations indicated channelization causes an additional 200,000 acre-feet per year to reach the lake during summer months and be discharged to the sea as part of hurricane protection.
