摘要

This report describes the available information on nutrients and suspendedsediment collected within the Lower Susquehanna River Basin. The report describes the spatial and temporal availability of nutrients and suspended-sediment data and presents a preliminary conceptual model of processes and the spatial and temporal patterns of concentrations and loads within the study unit. The scope of this report is limited to suspended-sediment and nutrient data collected during the water years 1975-90. The most complete analysis in the study was done on data collected during water years 1980-89. Data for total and dissolved forms of nitrogen and phosphprus in precipitation, surface water, springwater, ground water, and bottom material and data for suspended sediment in surface water were evaluated. the primary nitrogen and phosphorus data analyzed in this study were dissolved nitrite plus nitrate and total phosphorus.
