Daniel R Wise
Dan is a hydrologist with the U.S. Geological Survey at the Oregon Water Science Center in Portland, Oregon.
Biography
Dan's work is focused primarily on the interpretation of regional water quality data, such as relating surface-water nutrient and sediment conditions to landscape characteristics. He also works on the Integrated Water Availability Assessment for the Upper Colorado River Basin.
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, and has been with the USGS since 2001.

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
Using regional watershed data to assess water-quality impairment in the Pacific Drainages of the United States
Two datasets containing the first complete estimates of reach-scale nutrient, water use, dissolved oxygen, and pH conditions for the Pacific drainages of the United States were created to help inform water-quality management decisions in that region. The datasets were developed using easily obtainable watershed data, most of which have not been...

Changing climate drives future streamflow declines and challenges in meeting water demand across the southwestern United States
Society and the environment in the arid southwestern United States depend on reliable water availability, yet current water use outpaces supply. Water demand is projected to grow in the future and climate change is expected to reduce supply. To adapt, water managers need robust estimates of future regional water supply to support management...
Miller, Olivia L.; Putman, Annie Laura; Alder, Jay R.; Miller, Matthew; Jones, Daniel K.; Wise, Daniel Eroding Cascadia— Sediment and solute transport and landscape denudation in western Oregon and northwestern California
Riverine measurements of sediment and solute transport give empirical basin-scale estimates of bed-load, suspended-sediment, and silicate-solute fluxes for 100,000 km2 of northwestern California and western Oregon. This spatially explicit sediment budget shows the multifaceted control of geology and physiography on the rates and processes of...

Spatially referenced models of streamflow and nitrogen, phosphorus, and suspended-sediment loads in streams of the Pacific region of the United States
Although spatial information describing the supply and quality of surface water is critical for managing water resources for human uses and for ecological health, monitoring is expensive and cannot typically be done over large scales or in all streams or waterbodies. To address the need for such data, the U.S. Geological Survey developed SPAtially...

Spatially referenced models of streamflow and nitrogen, phosphorus, and suspended-sediment transport in streams of the southwestern United States
Given the predicted imbalance between water supply and demand in the Southwest region of the United States, and the widespread problems with excessive nutrients and suspended sediment, there is a growing need to quantify current streamflow and water quality conditions throughout the region. Furthermore, current monitoring stations exist at a...

Estimates of long-term mean daily streamflow and annual nutrient and suspended-sediment loads considered for use in regional SPARROW models of the Conterminous United States, 2012 base year
Streamflow, nutrient, and sediment concentration data needed to estimate long-term mean daily streamflow and annual constituent loads were compiled from Federal, State, Tribal, and regional agencies, universities, and nongovernmental organizations. The streamflow and loads are used to develop Spatially Referenced Regressions on Watershed...

Updates to the suspended sediment SPARROW model developed for western Oregon and northeastern California
A SPARROW (SPAtially Related Regressions On Watershed attributes) model that was previously developed for western Oregon and northwestern California was updated using advancements in the SPARROW software and refinements to the input data. As was the case for the original model calibration, the updated models used the NHD Plus Version 2 as a...

A spatially explicit suspended-sediment load model for western Oregon
We calibrated the watershed model SPARROW (Spatially Referenced Regressions on Watershed attributes) to give estimates of suspended-sediment loads for western Oregon and parts of northwestern California. Estimates of suspended-sediment loads were derived from a nonlinear least squares regression that related explanatory variables representing...

Estimation of total nitrogen and total phosphorus in streams of the Middle Columbia River Basin (Oregon, Washington, and Idaho) using SPARROW models, with emphasis on the Yakima River Basin, Washington
The watershed model SPARROW (Spatially Related Regressions on Watershed attributes) was used to predict total nitrogen (TN) and total phosphorus (TP) loads and yields for the Middle Columbia River Basin in Idaho, Oregon, and Washington. The new models build on recently published models for the entire Pacific Northwest, and provide revised load...
Johnson, Henry M.; Black, Robert W.; Wise, Daniel R. Water supply, demand, and quality indicators for assessing the spatial distribution of water resource vulnerability in the Columbia River Basin
We investigated water resource vulnerability in the US portion of the Columbia River basin (CRB) using multiple indicators representing water supply, water demand, and water quality. Based on the US county scale, spatial analysis was conducted using various biophysical and socio-economic indicators that control water vulnerability. Water supply...

Application of the SPARROW model to assess surface-water nutrient conditions and sources in the United States Pacific Northwest
The watershed model SPARROW (Spatially Referenced Regressions on Watershed attributes) was used to estimate mean annual surface-water nutrient conditions (total nitrogen and total phosphorus) and to identify important nutrient sources in catchments of the Pacific Northwest region of the United States for 2002. Model-estimated nutrient yields were...
Wise, Daniel R.; Johnson, Henry M. Surface-water nutrient conditions and sources in the United States Pacific Northwest
The SPAtially Referenced Regressions On Watershed attributes (SPARROW) model was used to perform an assessment of surface-water nutrient conditions and to identify important nutrient sources in watersheds of the Pacific Northwest region of the United States (U.S.) for the year 2002. Our models included variables representing nutrient sources as...

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.
USGS uses watershed modeling to assess surface-water nutrient impairment across the Pacific Northwest and California
The region-wide, reach-scale results from a new study provide two new tools that might help water-quality managers. One is an estimate of the total contribution from point and diffuse sources to the loads delivered to nutrient-impaired water bodies. The other is a method to assess potential nutrient impairment based on estimated warm-weather dissolved oxygen and pH conditions.
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.
