Abstract : The research work contained in this report concerns the transport of total phosphorus and orthophosphorus to Lake Erie. The various calculational techniques for analyzing data obtained from Lake Erie tributaries are presented. These calculations were developed to determine the source of the phosphorus and to quantify the input to the lake. The source and quantity of phosphorus devised for Lake Erie. The first section of this report presents the basic concepts, mass balances (that applied to the water and that applied to the phosphorus), and force relationships. The second section of this report concerns the quantification of total phosphorus input to Lake Erie river basins and shortline sources. A computational method called the Flow Interval Method was devised to permit the calculaion of total phosphorus influx without measuring the total phosphorus concentration for the entire year. Another important aspect of reducing total phosphorus influx from river basins is the understanding of the transport processes in rivers. The third section of this report concerns the transport of total phosphorus during storm events. The fourth section of this report presents the derivation of the necessary equations used to calculate the distance of the travel density function form measurements of the water flow rate and the total phosphorus concentrations at a point in the stream.
