Seasonal Flow Rates Along The Lower Bear River, Ut, Todd Keniry, Dahlia Curiel, Dylan Anderson, Ayman Alafifi, David E. Rosenberg
Seasonal Flow Rates Along The Lower Bear River, Ut, Todd Keniry, Dahlia Curiel, Dylan Anderson, Ayman Alafifi, David E. Rosenberg
Spring Runoff Conference
The goal of this research is to identify how flow on the Bear River in Cache Valley has changed over the last three years and how flow changes seasonally. Identifying flows is important to manage water resources along the Bear River. We collected and processed water pressure data every 30 minutes using HOBO transducers at two sites in Cache Valley (Morton, just downstream of highway 142, and Confluence which is located at the confluence of the Bear and Cub Rivers) south of the Idaho‐Utah border in 2015. We also measured flow and water stage up to three times per year …

In hydrology we straddle the domains of science and engineering. As hydrologists our goal is to predict the movement and volume of water. As scientists we seek to improve our understanding of water-related processes and how to model them. As engineers we seek to be able answer specific water-related questions to provide protection and an essential resource for the people we serve. Underlying all of our work is a body of knowledge that we have developed and continue to develop. This knowledge involves many aspects, such as the role of various hydrologic processes, how to obtain data, computational models that …

Revenue Recovery Through Meter Replacement, Devan J. Shields
Revenue Recovery Through Meter Replacement, Devan J. Shields
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Previous studies have identified water meter inaccuracy at low flow rates as a significant source of non-revenue flow for water systems; however a lack of available data makes it difficult to include low flow accuracy degradation in meter replacement plans. This thesis examines results from an extensive accuracy test program carried out at the Utah Water Research Laboratory on small water meters over a wide range of flow rates and at various levels of throughput. The study compares expected apparent losses of different types of water meters based on a flow profile and expected daily use for the State of …

A Sedimentation Study Of The Green River Irrigation Canal, Green River, Utah, Jan Michael Miller
All Graduate Plan B and other Reports, Spring 1920 to Spring 2023
This sedimentation study of the Green River irrigation canal provides the Green River Canal Company (GRCC) with a detailed aerial map of the Green River irrigation canal system to allow operators to quickly and accurately locate canal structures. Also, an Excel spreadsheet accounting model was created which provides the GRCC with the ability to determine where sedimentation likely occurs throughout the canal under given conditions. This model must be operated within set guidelines to provide reliable results and should be calibrated for increased accuracy. It was determined that with no irrigation (i.e., with no canal structures open except for the …
Hydraulic Characteristics Of Labyrinth Weirs, Corwin M. Willmore
Hydraulic Characteristics Of Labyrinth Weirs, Corwin M. Willmore
All Graduate Plan B and other Reports, Spring 1920 to Spring 2023
Primarily, half-round crest labyrinth weirs were tested in this study with the side leg angle (a) ranging between 7 to 35 degrees. Historical data was primarily limited to quarter-round data. This study presents data and equations for estimating the discharge coefficient for labyrinth weirs with both half-round, quarter-round, and two Ogee-type crest weir shapes . A method is presented for comparing the flow capacity between weirs in order to determine the most efficient weir at a given Ht/P. For a labyrinth weir with the crest shape,# of cycles (N), and the cycle width (w) held constant, the discharge coefficient (Cct) …
Tests Of A Suggested Piezometric Method For Determining Hydraulic Conductivity Of Saturated Soils, K. R. Channarasappa
Tests Of A Suggested Piezometric Method For Determining Hydraulic Conductivity Of Saturated Soils, K. R. Channarasappa
All Graduate Plan B and other Reports, Spring 1920 to Spring 2023
A major factor in the design of drainage systems is the hydraulic conductivity of the soil strata to be drained. Various methods for measuring the hydraulic conductivity of soils in both the field and the laboratory have been devised. In many cases, however, laboratory methods fail to give reliable data since the natural field conditions under which flow actually takes place cannot be duplicated in the laboratory. Hence a need exists for a field method for measuring hydraulic conductivity of soils in situ. When a large number of tests are to be performed in a given location, a simple, quick, …
