Utizing a lagrangian-eulerian approach to water-quality assessment of the wateree river, sourth chrolina

摘要

In preparation for developing a dynamic stremaflow and water-quality model to simulate flows and dissolved-oxygen concentrations in the Wateree River, South Carolina, a water-quality sampling scheme was designed based on Lagrangian and Eulerian reference frames. Designing a Lagrangian sampling scheme for the Wateree River was possible because data from a previous study were available, and the flows were known prior to the beginning of the study. By utilizing the previous data and models, the analytical laboratory cost for the sampling could be reduced by as much as 65 percent relative to an Eulerian sampling scheme. In addition, the water-quality data and field parameters for the Lagrangian water parcels could be used as a tool for assessing the major influences on the dissolved-oxygen concentrations before calibration of the model.
