Hydrologist, U. S. Geological Survey, performing applied research in hydrology and water quality that informs management of natural resources in Oregon and the Pacific Northwest, 1993-present

 

Biography

As a Hydrologist at the Oregon Water Science Center, my work is varied, encompassing river hydraulics, limnology of lakes and reservoirs, quantifying the availability of water resources, and characterizing the quality of those resources. The themes connecting all my work are the use of state-of-the-art modeling techniques tailored to each problem, and the data collection necessary to properly build and assess performance of those models. Project work accounts for 75% of my time. As a Team Lead, I facilitate a team of five Hydrologists both on my projects and to support their independent research directions. Supervisory activities account for 25% of my time.

Current and Recent Significant Projects

Assessment of Columbia and Willamette River Flood Stage on the Columbia Corridor Levee System at Portland, Oregon, in a Future Climate. Funded by Levee Ready Columbia. Background—Levees designed for flood protection along the Columbia River near Portland are being re-certified. Levee Ready Columbia requested an assessment of the effect of changing climate on flood stage on the levees. Approach—Delft-FM, a 2- and 3-dimensional hydrodynamic model was used to simulate Columbia River stage between Bonneville Dam and the Pacific Ocean. A methodology was developed with the US Army Corps of Engineers to scale up the boundary conditions to reflect extreme but plausible future events. Management Implications—Large rain-on-snow events in the 2040s could test the levee system in terms of its capacity to resist overtopping and seepage failure, especially if coincident with high tides and storm surge at the coast.

Quantification of Instream Flow Resulting from Curtailment of Irrigation in the Sprague River Basin, OR. Funded by the US Bureau of Reclamation. Background—Enforcement of senior water rights has resulted in an unmeasured increase in instream flow, which managers want to quantify. Approach—A machine learning approach was used to simulate streamflow in the absence of irrigation curtailment. Additional instream flow resulting from curtailment was determined by comparison. Management Implications—The machine learning approach was able to quantify the additional instream flow, even though it was small in comparison to total streamflow. Importantly for managers, rigorous confidence intervals around the estimates were calculated.

Model to Predict Availability of Light for Macrophyte Growth in Malheur Lake. Funded by the High Desert Partnership of Harney County, OR. Background—Invasive carp in Malheur Lake have created very turbid water by uprooting plants and leaving sediments exposed to resuspension.  Approach—Continuous measurements were used to determine light as a function of turbidity. A systems model created in STELLA was used to simulate turbidity in response to wind events, to be added to a carp population model. Management Implications—Previous restoration attempts focused solely on carp removal. Totally eliminating carp will be impossible. This work has revealed new pathways to restoration by managing sediment resuspension in addition to removing carp.

Deep mixing of Crater Lake in a future climate. Funded by USGS Science Support Partnership Program with U.S. National Park Service. Background—Deep mixing to the bottom of Crater Lake relies on cold winters. Such mixing replenishes nutrients at the surface and oxygen and the bottom. There is concern that a warming climate might making deep mixing less frequent. Approach—A research lake model designed to simulate mixing in very deep and cold lakes such as Lake Baikal was used in collaboration with researchers at the University of Trento. Future climate scenarios based on several general circulation models were used to simulate mixing of Crater Lake out to the year 2099. Management Implications—Deep mixing is predicted to occur less frequently in the future. Ongoing studies are examining the implications of this for water quality and water clarity.

Phosphorus and Chlorophyll model of Upper Klamath Lake to Simulate response to restoration activities. Funded by US Bureau of Reclamation. Background— The Oregon Department of Environmental Quality established a total maximum daily load for phosphorus in Upper Klamath Lake as a means to control annual cyanobacteria blooms. Approach— A whole lake model that can easily be run many decades into the future was developed to assess the magnitude and time scale of the response to tributary load reduction scenarios. Management Implications—There is an understanding that improvements will take decades to be fully realized. Updates and revisions of the model to address management questions are ongoing.
