Daniel R Wise
Biography
Dan is a hydrologist with the U.S. Geological Survey at the Oregon Water Science Center in Portland, Oregon. He received a B.S. in Civil and Environmental Engineering from Drexel University in 1990, an M.S. in Civil and Environmental Engineering from the University of Rhode Island in 1993, and an M.S. in Geography from Oregon State University in 2001. He has been with the USGS since 2001.
Dan's work is focused primarily on the interpretation of regional water quality data. His current research focuses on relating surface-water nutrient and sediment conditions to landscape characteristics using the USGS SPARROW model (Spatially Referenced Regressions on Watershed Attributes).
Science and Products
SPARROW Model Assessments of Nutrients and Suspended Sediment in the Pacific Northwest and California
SPARROW can be used to relate water-quality data to landscape characteristics, such as natural properties and human activities
SPARROW modeling: Estimating contaminant transport
What’s New: A new version of the SPARROW code is being developed in the R programming language. The advantage of R is that it is non-proprietary and does not require a license or software cost. The R – SPARROW code is now being completed and should be available early in CY18. Stay Tuned.
Surface-water nutrient and sediment mappers are now available
SPARROW mappers are interactive tools that allow users to evaluate streamflow and nutrient and sediment conditions as well as the importance of different sources of contaminants in a selected river basin. Data can be visualized at different scales using maps and interactive graphs and tables.
