Flow and water quality data (starting in 1976) have been collected, analyzed, and plotted at nine USGS gaging stations in the Sandusky River of northern Ohio for several storm events. A procedure has been developed whereby the water as it travels downstream is followed. The calculational procedure is further expanded to include the tracing of conservative water chemistry as it moves downstream. Thus, at a downstream station it is possible to predict such water quality parameters and compare them with their measured values. The conservative substances such as chlorides and conductivity compared well-- such substances indicating these are not conservative and that deposition and resuspension occur in various reaches of the stream. Further, the methodology permits the estimation of the fractions of these substances at a given downstream station which are derived from various upstream sources. Various factors such as point sources, river flow rate, etc., are discussed as to how they affect the transport of total phosphorus, suspended solids, chlorides, conductivity, the nitrogen species, and other water quality parameters.

Rivers are important agents of change that shape the Earth's surface and evolve through time in response to fluctuations in climate and other environmental conditions. They are fundamental in landscape development, and essential for water supply, irrigation, and transportation. This book provides a comprehensive overview of the geomorphological processes that shape rivers and that produce change in the form of rivers. It explores how the dynamics of rivers are being affected by anthropogenic change, including climate change, dam construction, and modification of rivers for flood control and land drainage. It discusses how concern about environmental degradation of rivers has led to the emergence of management strategies to restore and naturalize these systems, and how river management techniques work best when coordinated with the natural dynamics of rivers. This textbook provides an excellent resource for students, researchers, and professionals in fluvial geomorphology, hydrology, river science, and environmental policy.

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.
