An Open-Source, Semisupervised Water End-Use Disaggregation And Classification Tool, Nour A. Attallah, Jeffery S. Horsburgh, Camilo J. Bastidas Pacheco Jul 2023

An Open-Source, Semisupervised Water End-Use Disaggregation And Classification Tool, Nour A. Attallah, Jeffery S. Horsburgh, Camilo J. Bastidas Pacheco

Research Briefs

Research Objective/Summary: Research on individual household water consumption is vital to water management and conservation approaches. Despite a significant number of papers published on end-use disaggregation tools, reproduction and further study of results on water-use behavior is difficult because the data and code are not easily accessible. In order to fulfill this need for open and reproducible tools, we present a new, semisupervised, non-intrusive water end-use disaggregation and classification tool.

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 Feb 2019

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% …

Causal Loop Development Activity, Ali Mirchi Aug 2018

Causal Loop Development Activity, Ali Mirchi

All ECSTATIC Materials

Students will work in groups to develop a causal loop diagram (CLD) to illustrate the structure and expected behavior of the fictional water short state of Nevizonato facilitate qualitative discussion of expected outcomes of a proposed water management strategy. This activity requires familiarity with systems thinking and system dynamics modeling. CLDs are introduced as a fundamental systems thinking tool for conceptual modeling.


Utah Salt Storage Facilities Guidelines And Best Management Practices, Weston Bellon May 2018

Utah Salt Storage Facilities Guidelines And Best Management Practices, Weston Bellon

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

An environmental analysis was conducted at the Utah Water Research Laboratory of samples gathered from Utah Department of Transportation (UDOT) salt storage facilities retention ponds across the state. The analysis indicated high levels of TSS largely made up of minerals directly associated with the deicing solution currently used by UDOT in roadway applications. 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 …

The Influence Of Debris Cages On Critical Submergence Of Vertical Intakes In Reservoirs, Skyler D. Allen Dec 2008

The Influence Of Debris Cages On Critical Submergence Of Vertical Intakes In Reservoirs, Skyler D. Allen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This study quantifies the influence of debris cages on critical submergence at vertical intakes in reservoir configurations. Four model debris cages were constructed of light panel material. A vertical intake protruding one pipe diameter above the floor of a model reservoir was tested in six configurations: open intake pipe, a debris grate placed directly over the intake pipe, and debris cages representing widths of 1.5*d and 2*d and heights of 1.5*c and 2*c, where d is diameter of the intake and c is height of intake above reservoir floor. A selection of top grating configurations and a submerged raft configuration …
