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 ��ֱ�� graduate students, and our own Melissa Estep was recently chosen. Here's an excerpt:

My experience at ��ֱ�� 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. ��ֱ�� 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.

Fall 2018: Kasprzyk Research Group publications Anonymous (not verified) Fri, 10/26/2018 - 13:05

Our group has recently released several new publications.

Rebecca Smith expanded on her ParFAIT framework for assessing and improving tools in water resources research, with a new publication "Experimenting with Water Supply Planning Objectives Using the Eldorado Utility Planning Model Multireservoir Testbed", in the Journal of Water Resources Planning and Management. The study was co-authored by Leon Basdekas and Joseph Kasprzyk.

Also in the Journal of Water Resources Planning and Management was the work led by former MS student Tim Clarkin, who with Billy Raseman, Joseph Kasprzyk, and Jon Herman published "Diagnostic Assessment of Preference Constraints for Simulation Optimization in Water Resources".

We also collaborated on an optimization study for cooperative management of the Nile River, in Water Resources Research. The study included authors Kevin Wheeler, Jim Hall, Gamal Abdo, Simon Dadson, Joseph Kasprzyk, Rebecca Smith, and Edith Zagona.

Joseph Kasprzyk led an editorial on defining the role of water resources systems analysis in a changing future, co-authored with Rebecca Smith, Ashlynn Stillwell, Kaveh Madani, David Ford, Daene McKinney, and Soroosh Sorooshian in the Journal of Water Resources Planning and Management.

Former group member Amy Piscopo, and Joseph Kasprzyk contributed to "Embedding co-production and addressing uncertainty in watershed modeling decision support tools: Successes and challenges" published in Environmental Modelling and Software. This review paper had several co authors and was led by Bradley Barnhart.

Welcome new students Anonymous (not verified) Wed, 10/03/2018 - 10:53

Over the last several months, we are proud to welcome multiple students to the research group!

Prof. Kasprzyk recently started co-advising Leah Bensching, an MS student who is a member of Prof. Ben Livneh's research group and is set to defend in Fall 2018.

MS student Michelle O'Donnell joined the group in Fall 2018. She will be continuing the collaboration with Prof. Livneh, investigating reservoir sedimentation and the management implications of different rates of sedimentation from water supply watersheds.

We are proud to be a part of the College of Engineering and Applied Science's DLA program for the second year in a row. Jacob Tiede, a BS student in Applied Math, is working with PhD student Mikaela DeRousseau investigating life cycle analysis for sustainable concrete mix design.

Summer 2018 Publications

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 ��ֱ��. 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.

The Kasprzyk group recently attended three conferences. At the American Society of Civil Engineers Environmental Water Resources Institute meeting in Minneapolis, MN, Elliot presented our work on decision making for the ��ֱ�� River Basin and Prof. Kasprzyk presented on a new reclaimed water project that Brendan is working on with Prof. Ashlynn Stillwell. Prof. Kasprzyk also discussed the water treatment plant optimization at the American Water Works Association meeting in Las Vegas, NV. And at the International Environmental Modelling and Software Society meeting in Fort Collins, CO, Billy presented his new time series analysis method for water quality data, and Mikaela discussed multi-objective optimization for building materials with an improved compressive strength statistical model.

Raseman Drinking Water Research Featured in ��ֱ�� News

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

Billy Raseman’s drinking water optimization research was highlighted in a ��ֱ�� 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.
