A dynamic one-dimensional lake model has been developed in alternative structures, MINLAKE and FRMPND, for water-quality control strategies and lake eutrophication studies. Hydrophysical components including thermal stratification, mixing, and suspended sediment and solid concentrations comprise the first step in water quality modeling for management predictions. Validation tests showed that both model structures satisfactorily simulated temperature stratification and inflow/outflow regimes, although simulated sediment profiles did not reproduce field data due to inexact and questionable measurements.
