Adaptive Policy Design In Water Resources Systems Under Uncertain Climate And Human Stressors, Jon Herman

All ECSTATIC Materials

Long-term planning of water resources systems must contend with severe uncertainty in future projections of hydroclimatic variability across multiple scales, as well as uncertainty in human behavior, such as land use and reservoir operation. This talk will review recent developments in adaptive policy design to meet this challenge, centered around the key question: how should we learn from, and react to, dynamic observations of hydroclimatic, human, and ecological variables to ensure long-term sustainability? Specific contributions will cover three areas: (1) adaptation of short-term control rules, enabling existing infrastructure to manage multiple objectives across a range of possible futures; (2) exploration …

Strategies For Managing The Colorado River In An Uncertain Future, Jian Wang

All ECSTATIC Materials

Colorado River managers face a deeply uncertain future. Projections of declining watershed runoff are likely to necessitate restructuring of the present interpretation of the Law of the River that allocates water supply among Mexico and the seven states of the Basin. Additionally, the magnitude and distribution of consumptive uses of water will change. Outcomes for river and reservoir ecosystems are poorly predicted. How should we make better decisions given these uncertain factors? To help answer this question and expand conversation about the Colorado River management issues, we (1) classify different levels of uncertainty to guide decisions about which modeling tools …

Impacts Of Beaver Dams On Mountain Stream Discharge And Water Temperature, Timothy R. Clark

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Beaver dam complexes have been shown to affect the hydrologic processes controlling river systems. These processes include surface and groundwater exchanges, water chemistry and temperature variations, and river discharge magnitudes. Majerova et al. (2015) explored the effects of beaver dams on surface and groundwater exchanges and water temperature by evaluating three years of water discharge and temperature data recorded at multiple locations within a small stream in northern Utah. They found that beaver dams increase the water surface elevation and force water into the floodplain resulting in increased inundation and groundwater recharge. They additionally found that beaver dams increase residence …

Designing Technology For Different Scales Of Irrigation Scheduling, Paolo Alexander Consalvo

Undergraduate Honors Capstone Projects

Uncertainty in water availability is a significant challenge to the agriculture industry. Farmers and irrigators depend on novel uses of sensors and data to maximize water efficiency. Documented studies have demonstrated scheduling irrigation is a straightforward, deterministic means of achieving water efficiency. Irrigation scheduling uses several parameters to determine the moment of crop water stress due to available water in the soil. However, sensors and data for soil moisture and matric potential, a parameter describing water available to plants, have the potential to train machine learning algorithms to forecast water irrigation needs based on previous measurements. Satellite remote-sensing is another …

A Practitioner’S Guide To Small Unmanned Aerial Systems For Bridge Inspection, Sattar Dorafshan, Robert J. Thomas, Calvin Coopmans, Marc Maguire

Electrical and Computer Engineering Faculty Publications

Small unmanned aerial system(s) (sUAS) are rapidly emerging as a practical means of performing bridge inspections. Under the right condition, sUAS assisted inspections can be safer, faster, and less costly than manned inspections. Many Departments of Transportation in the United States are in the early stages of adopting this emerging technology. However, definitive guidelines for the selection of equipment for various types of bridge inspections or for the possible challenges during sUAS assisted inspections are absent. Given the large investments of time and capital associated with deploying a sUAS assisted bridge inspection program, a synthesis of authors experiences will be …

Assessing Data Availability And Research Reproducibility In Hydrology And Water Resources, James H. Stagge, David E. Rosenberg, Adel M. Abdallah, Hadia Akbar, Nour A. Atallah, Ryan James

Civil and Environmental Engineering Faculty Publications

There is broad interest to improve the reproducibility of published research. We developed a survey tool to assess the availability of digital research artifacts published alongside peer-reviewed journal articles (e.g. data, models, code, directions for use) and reproducibility of article results. We used the tool to assess 360 of the 1,989 articles published by six hydrology and water resources journals in 2017. Like studies from other fields, we reproduced results for only a small fraction of articles (1.6% of tested articles) using their available artifacts. We estimated, with 95% confidence, that results might be reproduced for only 0.6% to 6.8% …

As a companion to that analysis, best management practices have been identified and compiled to provide a resource for the proper management of salt storage facilities in the state of Utah. Topics included as best management practices include locating new storage facilities, proper salt storage, proper salt …

Comparing Sandwich Wall Panel Shear Connector Testing Methodologies, Parker S. Syndergaard

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Precast concrete sandwich wall panels (PCSWPs) have been used in the precast industry for decades due to their durability, rapid construction, and thermal efficiency. Shear connectors are used to connect the two wythes of concrete to allow composite action of the system. In order to design concrete sandwich panel systems to act compositely, the engineer must obtain design values from a connector manufacturer, often times making engineers uncomfortable. Shear connectors are typically proprietary, and are required to first have design values validated through destructive testing. The method in which connectors are validated often times varies by each company. This project …

Advancing Distributed Data Management For The Hydroshare Hydrologic Information System, Hong Yi, Ray Idaszak, Michael Stealey, Chris Calloway, Alva L. Couch, David G. Tarboton

Civil and Environmental Engineering Faculty Publications

HydroShare (https://www.hydroshare.org) is an online collaborative system to support the open sharing of hydrologic data, analytical tools, and computer models. Hydrologic data and models are often large, extending to multi-gigabyte or terabyte scale, and as a result, the scalability of centralized data management poses challenges for a system such as HydroShare. A distributed data management framework that enables distributed physical data storage and management in multiple locations thus becomes a necessity. We use the iRODS (Integrated Rule-Oriented Data System) data grid middleware as the distributed data storage and management back end in HydroShare. iRODS provides a unified virtual file system …

Milwaukee Wet Weather Flow Management System Planning, David Watkins

All ECSTATIC Materials

Many older cities across the United States rely on combined sewers to convey both stormwater runoff and sanitary sewage. Combined sewer overflows (CSOs), containing untreated sewage, occur during extreme wet weather, when the capacity of these combined sewer systems is exceeded. Across the U.S., CSOs pose a serious threat to water quality in thousands of lake, river, and coastal ecosystems. In addition to harming the natural environment, they may be a threat to human health and have adverse economic consequences (e.g., beach closings, reduced aesthetics, tourism impacts).

In this assignment, students role-play engineering consultants tasked with developing a cost-effective plan …

Statistical Models Of I-15 Bridge C-846: Changes In Natural Frequencies Due To Temperature, Gilbert Nichols

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Structural Health monitoring is to determine the condition of a bridge based on instrument measurements. The C-846 Bridge in Salt Lake City has such instrumentation. The bridge is located in Salt Lake City at about 2100 South and Interstate 15. This bridge has two kinds of instruments on it: accelerometers and thermocouples. The accelerometers measure the vibrations of the bridge. The accelerometers have been recording data on the bridge since 2001. The thermocouples, which measure temperature, were added as part of this thesis in April 2016.

In light of recent research, damage may be detected from measuring the change in …

Developing A General Methodology For Evaluating Composite Action In Insulated Wall Panels, Jaiden Thomas Olsen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Precast Concrete Sandwich Panel Walls (PCSPW’s) have been in use for over 60 years. They provide a very efficient building envelope for many buildings. Characteristic PCSPW’s comprise an outer and inner layer (or wythe) of concrete separated by an insulating material. To use all of the material as efficiently as possible, the layers are attached by connectors which penetrate through the insulating layer and are embedded in either concrete wythe. These connectors make it possible for both layers of the wall to work together when resisting loads. The connectors are made out of plastic, or FRP, to prevent heat transfer …

Design Of A Metadata Framework For The Environmental Models With An Example Hydrologic Application In Hydroshare, Mohamed M. Morsy, Jonathan L. Goodall, Anthony M. Castronova, Pabitra Dash, Venkatesh Merwade, Jeffrey M. Sadler, Mohammad Adnan Rajib, Jeffery S. Horsburgh, David G. Tarboton

Civil and Environmental Engineering Faculty Publications

Environmental modelers rely on a variety of computational models to make predictions, test hypotheses, and address specific problems related to environmental science and natural resource management. Scientists and engineers must devote significant effort to preparing these computational models. While significant attention has been devoted to sharing and reusing environmental data, less attention has been devoted to sharing and reusing environmental models. A first step toward increasing environmental model sharing and reuse is to define a general metadata framework for models that is flexible and, therefore, applicable across the wide variety of models used by environmental modelers. This paper proposes a …
