Project: Framework for Quantification of Risk and Valuation of Flexibility in the FCRPS (November 2015-October 2018)
Description: The results of this research will allow the Bonneville Power Administration (BPA) to balance capabilities and resources in the Federal Columbia River Power System (FCRPS) by providing the flexibility to better utilize resources to maximize revenue, without wasting resources due to uncertainties in operation or the market. The accurate quantification and valuation of flexibility will provide guidance to BPA on when to optimally move electricity generation from one period to another, which would allow BPA to maximize revenue while increasing the reliability of the operation of reservoirs in the FCRPS to meet the electricity demands in the Pacific North West.

Project: Development of a state-of-the-art computational framework and platform for the optimal control of multi-reservoir systems under uncertainty (September 2012-October 2015)
Description: We propose to develop a robust and computationally efficient framework for the real-time operation of multi-objective and multi-reservoir systems that accounts for uncertainty and flexibility.  In pursuit of this goal, we will devise a novel methodology for the incorporation of uncertainty into the system, investigate hybrid optimization approaches, allow for scalable parallelization in our numerical methods and combine all components into an integrated platform with a user-friendly graphical interface.

Project: Early Career: Prediction and quantification of CSOs in combined sewer systems under extreme storm events: Extreme events, Flow dynamics, Reduction of CSOs (June 2012-May 2017)
Description: The overall goal of the proposed research is to develop an overflow framework for the prediction and quantification of time-dependent overflow rates (e.g., CSOs) especially when the flow in the combined sewer system is highly dynamic (e.g., extreme events). The specific objectives of the research are:
(1)to develop a mathematical formulation for common cases of overflow discharges at open outlets (vertical shafts and near-horizontal outlets) under unsteady flow conditions (e.g., extreme events), (2) to implement the mathematical formulation of overflows into a state-of-the art open source transient flow model, (3) to validate the overflow discharge framework under highly dynamic flow conditions (e.g., extreme events). A hydraulic model of the Portland combined sewer system will be built in the Hinsdale Wave Research Laboratory at Oregon State University, which will be used for the validation. (See webpage)

Project: Multi-purpose river hydraulics research facility (March 2012-December 2013)
Description: Design and construction management of the “Multi-purpose river hydraulics research facility”.

The river facility consists of a re-circulating system with a 20 m x 8 m concrete slab (platform for experiments), two independent head tanks, a sediment catchment, a clean water sump, pumps, and impulsion and return pipe lines. This hydraulic facility has been designed to accommodate two simultaneous and independent experiments. Any of these experiments could use flows up to 1000 L/s (~ 35 cfs). This river facility is a multi-purpose testing system that could be used for a large set of research projects such as flood control, reservoir sedimentation, density currents, erosion and scour, aquatic habitat, stream restoration, fish passage, hydraulic structure testing and dam removal.
