The Utah Snow Load Study, Brennan Bean, Marc Maguire, Yan Sun
Civil and Environmental Engineering Faculty Publications
Recent reports of snow related building collapses across the western United States in early 2017 highlight the importance of snow load considerations in building design. Specifying such design snow loads requires a proper balance between safety and economy. As articulated by Nowak and Collins (2012): "Conceptually, we can design [a] structure to reduce the probability of failure, but increasing the safety...beyond a certain optimum level is not always economical." It is the search for this optimum level of safety that has motivated the development of design ground snow loads at state and local levels.

PRELUDE
On June 26, 2012 a lightning strike ignited a wildfire in the Manti-La Sal National Forest of central Utah’s Carbon and Emery counties (Figure P.1). By the time the Seeley wildfire was contained three weeks later, some 48,000 acres of federal, state, and private land had been burned and $8.7 million in suppression costs expended (Styler 2012). According to the Monitoring Trends in Burn Severity (MTBS.gov) project, nearly one-third of the acreage was severely burned, damaging vegetation and soils for years to come. Severe burns vastly increase the erosion potential of burnt landscapes, and the steep lands of Huntington …

Report To The Utah Legislature Number 2015-01: A Performance Audit Of Projections Of Utah's Water Needs, John M. Schaff
All In-stream Flows Material
The Division of Water Resources’ projections indicate that Utah’s statewide demand for water will outstrip the currently developed supply in about 25 years. Some believe the state can address its growing demand for water through conservation and by developing local supplies, including the conversion of agriculture water to municipal use. Others believe the state’s growing demand for water will require the development of major new sources of supply that will cost billions of dollars. Considering the importance of water to the health, social and the economic well-being of our state’s residents, it is essential that the division provide the best …

Watershed Management And Water Production Study For State Of Utah, Ibrahim Nourein Mohammed, David G. Tarboton
Civil and Environmental Engineering Faculty Publications
The amount of water produced from a watershed depends on the climate, soils, geology, land cover and land use. Precipitation water inputs in the form of rain or snow are partitioned by the watershed into evapotranspiration, runoff and groundwater recharge. This study has examined factors that may impact the production of runoff from Utah watersheds, focusing on factors related to land and watershed management. Specifically we are interested in how land use changes, such as afforestation, deforestation, agricultural, urban, industrial and mining development, impact runoff. The scale of interest is regional subbasins at the USGS cataloging unit 8 digit Hydrologic …

Preliminary Pumping Strategy Analyses For Southeastern Cache Valley, Utah And River Baseflow Impacts, Shyamal B. Chowdhury, Richard C. Peralta
Civil and Environmental Engineering Faculty Publications
US/REMAX, a linear optimization model for groundwater management, is used to compute preliminary optimal sustained groundwater pumping increases for southeastern Cache Valley. US/REMAX employs the response matrix method of representing system response to stimuli as constraint equations within an optimization problem. The management objective is to maximize groundwater extraction at four specified locations subject to constrai~ts on aquifer potentiometric head, aquifer/river interflow, and the water level in the uppermost aquifer layer. Four scenarios (constraint sets) are presented. The results are most sensitive to the aquifer/river interflow constraints. Interflow is deemed important because baseflows are crucial to satisfying fish, aquatic life, …
Optimal Perennial Groundwater Yield Planning For The East Shore Area, Utah, Shu Takahashi, Richard C. Peralta
Optimal Perennial Groundwater Yield Planning For The East Shore Area, Utah, Shu Takahashi, Richard C. Peralta
Civil and Environmental Engineering Faculty Publications
Computer models are developed for computing optimal perennial groundwater withdrawal strategies for the East Shore Area of Utah's Great Salt Lake. The underlying aquifer has three confined or unconfined layers. Both embedding and response matrix (RM) approaches are tested and compared. Historically, it has been difficult to incorporate simulation of an unconfined aquifer and many external flow equations described by nonsmooth functions within linear programming models. RM models normally assume system linearity. The presented RM model overcomes this difficulty using cycling and influence coefficients generated with a modified MODFLOW model. In this groundwater flow simulation model, the above nonlinear terms …

Optimal Sustained-Yield Groundwater Pumping Strategy For The East Shore Area, Utah, Shu Takahashi, Richard C. Peralta
Civil and Environmental Engineering Faculty Publications
Optimal sustained-yield pumping strategies were developed for the irrigated and industrialized eastern shore of the Great Salt Lake. The combined optimization and simulation model contains steady-state, finite difference, quasi-three-dimensional, groundwater flow equations embedded as constraints. The model computes the optimal spatial distribution of sustainable annual groundwater pumping rates for alternative scenarios. The addressed aquifer is a multilayer and confined/unconfined (linear/nonlinear) system. The research can help manage water in the study area, where the demand for water of sufficient quality and quantity is increasing due to urbanization.

Utah is an arid state, without the abundant surface water resources enjoyed by states in the humid east. Most precipitation in the state falls in the higher elevations of the Uinta and Wasatch mountains of northern and central Utah. Much of this precipitation ultimately ends up in alluvial deposits at the base of these ranges, from which the vast majority of pumping wells draw their water (Barnes and Croft, 1986). This groundwater is an essential resource for use by the people of Utah. About sixty-three percent of Utah's population is at least partially reliant on groundwater for domestic use. In …

Multiple Uses Of Utah Irrigation Canals: Cache County As A Case Study, James J. Kennedy, Komain Unhanand
Reports
Irrigation use is an obvious benefit of Utah canals that has been recognized for over 100 years. This study attempts to illustrate other, less obvious, uses. the major use examined was recreational, but canals are presently functioning as storm drainage systems and have potential for diverting flood crests in many river systems.
Recreational use of canals falls into two categories. There is passive use such as its landscape values, affects on creating shade and bird-wildlife habitat, etc., that is difficult to quantify but no less important than active canal use such as tubing, hiking, bank-play, bicycling, etc. We selected several …
