Abstract
Increasing pressures toward efficient decision-making in water pollution control are creating the need for improved pollutant routing models. Such mathematical models help understand cause and effect relationships between sources of pollutants and their ensuing concentrations at various locations in a basin. Considered in the study were both flow and water quality processes occurring on the ground surface, in the unsaturated soil zone and in the saturated or groundwater zone. The objective was to improve already available formulations for the above processes and subsequently to develop a methodology for interfacing the individual models. Emphasis was placed on the modeling of agricultural pollution. For this reason, nitrogen and phosphorous were the main substances considered. The selection of the Lake Apopka Basin in Central Florida as the study area was made in accordance with these project goals.
