Murphy, J.C., 2021, Data to Incorporate Water Quality Analysis into Navigation Assessments as Demonstrated in the Mississippi River Basin: U.S. Geological Survey data release, https://doi.org/10.5066/P9GQNK12.

Summary

This data release includes estimates of annual and monthly mean concentrations and fluxes for nitrate plus nitrite, orthophosphate and suspended sediment for nine sites in the Mississippi River Basin (MRB) produced using the Weighted Regressions on Time, Discharge, and Season (WRTDS) model (Hirsch and De Cicco, 2015). It also includes a model archive (R scripts and readMe file) used to retrieve and format the model input data and run the model. Input data, including discrete concentrations and daily mean streamflow, were retrieved from the National Water Quality Network (https://doi.org/10.5066/P9AEWTB9). Annual and monthly estimates range from water year 1975 through water year 2019 (i.e. October 1, 1974 through September 30, 2019). [...]

Purpose

The estimates of annual and monthly mean concentrations and fluxes for nitrate plus nitrite, orthophosphate and suspended sediment are used to describe and compare annual and monthly variability at nine sites in the Mississippi River Basin and discuss ways of incorporating water quality analyses into navigation assessments.

Provenance

Input data from the USGS National Water Quality Network ScienceBase page were used to run the Weighted Regressions on Time, Discharge, and Season model and estimate outputs of annual and monthly concentrations and loads for nitrate plus nitrite, orthophosphate, and suspended sediment for nine sites in the Mississippi River Basin.
