Lysimeter Use in Water Rights Determination
In the Western United States, a water right (the legal right to divert water from a stream) is a property right. The impact a water right has upon a stream is commonly defined through...

Water Table Lysimeter Data Interpretation
Lysimeters were used to estimate seasonal water use of wet meadows and phreatophytes in northern Utah, southeast Idaho and southwest Wyoming (1983-1990). Twelve water table lysimeters...

Remediation and Mitigation Associated with Contamination of Water by Irrigation Drainage
Inorganic trace constituent or pesticide contamination problems associated with irrigation drainage from Federally constructed or managed irrigation projects have been identified in several...

Infiltration of Unconsumed Irrigation Water in Utah
The ground-water hydrology of Panguitch Valley and adjacent areas, south-central Utah, was studied during 1988-90. One objective of the study was to measure ground-water recharge from...

Direct Load Cell-Based Weighing Lysimeter System
A low-cost weighing lysimeter system is described which is capable of measuring evapotranspiration with an accuracy of 0.05-0.10 mm. A two-lysimeter system with electronic data logger...

Optimal Aquifer Planning with Salt Water Boundary

Investigating Fault Rupture Hazards: An Example from the Wasatch Fault Zone, Utah
The Kern River project consists of a 36-inch diameter high-pressure natural gas pipeline, to be constructed from southwestern Wyoming to southern California. The alignment crosses several...

Use of Lysimeters for Determining Characteristics of Pore Water
Lysimeters have been installed and used during the cleanup and stabilization of several former uranium processing sites in the western United States. In particular lysimeters have been...

Restructuring of Water Agencies in Salt Lake Valley, Utah
The Salt Lake Valley consists of a metropolitan area with a population of about one million. Wholesale domestic water supply is provided to this area by two main agencies, namely Salt...

A Case for Modernizing the Funding and Repayment of Regional Water/Power Projects
Several regional water/power projects authorized by Congress remain unfunded and therefore uncompleted year after year. In this paper examples of such uncompleted projects are examined....

Evaporation and Snowmelt Estimates from Satellite Data
Satellite imagery has been used to estimate saltwater evaporation and snowmelt runoff. Water surface temperatures can be obtained from satellite thermal infrared data. Saltwater evaporation...

Spectral Analysis of Annual Time Series of Mountain Precipitation
In this paper we examine the statistical moments of long record, annual, precipitation time series for 19 west facing stations along the Wasatch Front, northern Utah. The mean, variance,...

Utah Sewage Treatment Plant Uses New Process

Debris Flow Potential and Sediment Yield Analysis Following Wild Fire Events in Mountainous Terrain
The Pacific Southwest Inter-Agency Committee (PSIAC) 1968 Sediment Yield Rating Model provides a method to rapidly assess any increase in potential sediment yields following a wild fire...

Large Floods and Climate Change in the Southwestern United States
Floods can have a tremendous impact on water resources but their properties may fluctuate at frequencies that defy recognition in short-term instrumented records. Paleoflood deposits provide...

Multiple Phenomena of Debris-Flow Processes: A Challenge for Hazard Assessments
Hazardous hydraulic processes associated with arid environments commonly repesent significant risks to the safety of the public. However, the public generally considers these risks to...

Recurrence of Debris Flows on an Alluvial Fan in Central Utah
In the spring of 1983 a large debris flow occurred in the drainage of Birch Creek, near Fountain Green in central Utah. During the debris-flow activity, a new channel was incised into...

Structural Control of Ground-Water Induced Debris Flows
A number of case studies have attributed debris flow initiation to the effect of elevated pore pressure from a bedrock ground-water source. Debris flows on slopes underlain by Precambrian...

Geomorphology and Sedimentology of a Valley Fan, Southern Utah
Sink Valley, located in semi-arid west-central Kane County, Utah, lies on an erosional surface of Cretaceous age Tropic Shale. The valley contains an example of a previously undocumented...

Potential Sediment Yield From a Burned Drainage - An Example From the Wasatch Front, Utah
Two debris flows hit Mapleton City, Utah, as a result of rainstorms on a steep drainage basin, which had recently been burned. Debris flow potential for the area was evaluated to determine...
