You can now find a preprint of our NOAA-funded work on using deep learning and snowpack information in an ensemble streamflow prediction model on the ESS Open Archive!

The paper's lead author was PhD student Parthkumar Modi, and co-authors are Keith Jennings, Joseph Kasprzyk, Eric Small, Cam Wobus, and Ben Livneh.

The paper assesses whether the Long Short-Term Memory model can provide skillful forecasts when used in an ensemble streamflow prediction mode, with multiple model types including explicit snowpack information to improve the hydrologic memory representation.

Melissa Estep interviewed by CEAE department Anonymous (not verified) Wed, 11/07/2018 - 09:44

The CEAE department is conducting a series of interviews with CU graduate students, and our own Melissa Estep was recently chosen. Here's an excerpt:

My experience at CU has proven to be what I expected and more. All of the graduate students I have worked with have been incredible people, many of which are now my friends. The professors are clearly passionate about their work, making the courses engaging. There are opportunities to expand my learning if I make the effort to do so, through seminars from my department and others. The graduate department truly feels like a close community. CU as a whole also offers great services for its students through its health department and student events. And of course, the picturesque views of the Flatirons and the Indian Peaks beyond are not a terrible backdrop for studying.

Summer 2018 Publications Anonymous (not verified) Mon, 07/16/2018 - 12:05

We have a diverse set of new publications out recently!

Tim Clarkin's master's work, published in Journal of Water Resources Planning and Management, showed the effect of including preference constraints on optimizing water resources problems -- both on how easy it is to interpret the tradeoffs, and whether or not the constraints make the problem easier to solve. The paper was co-authored by Clarkin, Prof. Kasprzyk, and Prof. Jon Herman of the University of California Davis.

Rebecca Smith also has a study published in the Journal of Water Resources Planning and Management, which presents the Eldorado Utiltiy Model and demonstrates interesting ways of formulating water resources planning problems, including objectives and decisions in a manner informed by our ongoing work engaging water managers in the Front Range of babyֱ��app. The paper was co-authoed by Smith, Prof. Kasprzyk, and Leon Basdekas of Black and Veatch.

Mikaela DeRousseau published a review of computational optimization for concrete mix design, in Cement and Concrete Research. This extensive review paper highlights different types of property modeling and optimization formulations in this field, co-authored by DeRousseau, Prof. Kasprzyk, and Prof. Wil Srubar.

Raseman Drinking Water Research Featured in CU News

Raseman Drinking Water Research Featured in CU News Anonymous (not verified) Fri, 08/04/2017 - 00:00

Billy Raseman’s drinking water optimization research was highlighted in a CU press briefing. Below is an excerpt from the story, but click here to read the whole thing!

Since the only guarantee in life is change, William Raseman is using his research to try to prepare water municipalities from being crippled by unforeseen circumstances such as floods, droughts or wildfires.

The second-year civil engineering PhD student is building software programming to assess the impact of climate and environmental change on drinking water decisions. Working under Assistant Professor Joseph Kasprzyk, Raseman is learning to use multi-objective evolutionary algorithms to help water municipalities make decisions that will be resilient against future climate change induced challenges.

Or, more simply, he is building computer programs to simulate disasters and then generate possible solutions to them.

“We can’t fix everything the right way,” Raseman said of current water infrastructure systems. “We have what we have and so we need to make the systems we already have more adaptable to changing conditions.”

This means finding a way to modify the systems already in place to best serve the needs of the present and future. He gave the example of a Fort Collins water treatment plant that recently cut off intake from the river from because of a wildfire nearby. The drastic increase in sediment made the water untreatable for 100 days. Though this plant had access to a reservoir as backup, Raseman questioned possible outcomes if a backup source wasn’t available.

Congratulations Tim Clarkin

Congratulations Tim Clarkin Anonymous (not verified) Thu, 05/19/2016 - 00:00

Congratulations to Tim Clarkin, who defended his MS thesis and graduated in Spring 2016. After graduation, Tim will begin working for the U.S. Army Corps of Engineers as part of the SMART Scholarship-for-Service Program.

Tim’s thesis explored how user-defined constraints affect the effectiveness, efficiency and consistency of multi-objective evolutionary algorithm (MOEA) optimization in water resources. Constraints in MOEA optimization commonly represent limits on acceptable performance, but their effect on MOEA performance had not been extensively researched. His study considered two water resources case studies: a water supply portfolio planning model and an babyֱ��app development and environmental water quality model. These models were optimized in two different cases: one with constraints – as the models were originally formulated – and one without constraints. The original set of constraints were then applied a posteriori to all solutions, representing a typical decision making process. For each model, the effectiveness and efficiency of search on the constrained and unconstrained problems were compared. This work was done in collaboration with Prof. Jon Herman of UC Davis and Kasprzyk group student Billy Raseman.

With his work for the Army Corps, he is assigned to the Galveston District in Texas, which provides and maintains coastal storm risk management (CSRM) and navigation channels along the Texas coast. Possible projects include the Sabine Pass to Galveston Bay Feasibility Study and the Texas Coastal Planning Study — two ongoing CSRM studies for the Texas Coast.

We wish Tim the best of luck!
