Savant Sage Record Of Decision, United States Forest Service Jan 1994

Savant Sage Record Of Decision, United States Forest Service

All U.S. Government Documents (Utah Regional Depository)

The 7,500-acre Savant Sage Resource Area forms a mountainous backdrop and prominent landscape for the communities of Athol, Belmont and the surrounding areas. The majority of the area was burned by the fires of the late 1800's, and there has been little timber resource management since. During early scoping activities, the public expressed concern for personal use of water resources in the area; the importance of visual resources to both local residents and seasonal visitors to the area; the forest health of the area; and the complexity of the area as a whole.

Open Stream Collection And Diversion: An Added Dimension In Providing Water For Grazing Animals, United States Bureau Of Land Management Jan 1994

Open Stream Collection And Diversion: An Added Dimension In Providing Water For Grazing Animals, United States Bureau Of Land Management

All U.S. Government Documents (Utah Regional Depository)

This technical note describes an effective system for collecting water from open streams and conveying it several miles via pipeline systems to watering troughs in arid locations. Perhaps one of the greatest challenges in managing lands that produce forage for grazing animals is to strike a desirable balance between forage and water. However, on native grazing lands, this is rarely the case due to terrain and uneven distribution of water. The "open stream collection and diversion system" addresses this issue with a specific engineering solution.

Vandalism Of Rock Art For Enhanced Photography, S. D. Chaffee, M. Hyman, M. W. Rowe Jan 1994

Vandalism Of Rock Art For Enhanced Photography, S. D. Chaffee, M. Hyman, M. W. Rowe

Canyonlands Research Bibliography

Direct radiocarbon dating of pictographs has recently become possible. The authors report here the deleterious effects on such dating of hydrocarbon contamination of a pictograph in southeastern Utah. In order to enhance contrast between a pictograph and its rock substrate, some photographers have wetted pictographs with kerosene or similar substances; such 'enhancement' renders radiocarbon dates useless. Some treatments proposed for rock art deterioration may cause similar problems.

Selecting Controls For Water Distribution Systems, J. Paul Tullis Jan 1994

Selecting Controls For Water Distribution Systems, J. Paul Tullis

Reports

One of the key requirements for reliable operations of a water supply system is a thorough analysis and proper selection of the control valves and pumps. For valves, selection criteria includes capacity, pressure loss, controllability, torque, cavitation and transients. Pump selection requires matching the pump performance to varying system demands. Examples are given for single pump operation and use of pumps in series and parallel. When future demands exceed the original design conditions, or if significant changes are required in the operation of the system, each important control device should be analyzed to see if it can operate safely at …

Antecedent Moisture Conditions For Utah Local Storm Probable Maximum Floods, Travis S. Taylor, David S. Bowles Jan 1994

Antecedent Moisture Conditions For Utah Local Storm Probable Maximum Floods, Travis S. Taylor, David S. Bowles

Reports

Introduction: The critical inflow design flood for most dams in Utah is the probable maximum flood (PMF) resulting from the local storm probable maximum precipitation (PMP) event. Commonly, the Soil Conservation Service (SCS) curve number method is used to determine the PMF from the local storm PMP. An important factor in this determination is the assumption of antecedent moisture conditions (AMC) existing immediately prior to the onset of the PMP event. At one northern Utah dam site the use of AMC III increased the PMF peak flowrate by 50 percent over the peak obtained when AMC II was used (Win …

A Spatially Distributed Energy Balance Snowmelt Model, David G. Tarboton, Tanveer G. Chowdhury, Thomas H. Jackson Jan 1994

A Spatially Distributed Energy Balance Snowmelt Model, David G. Tarboton, Tanveer G. Chowdhury, Thomas H. Jackson

Reports

This paper describes an energy balance snowmelt model developed for the prediction of rapid snowmelt rates responsible for soil erosion and water input to a distributed water balance model. The model uses a lumped representation of the snowpack with two state variables, namely, water equivalent and energy content relative to a reference state of water in the ice phase at 0 degrees Celcius. This energy content is used to determine snowpack average temperature of liquid fraction. This representation of the snowpack is used to determine snowpack average temperature of liquid fraction. This representation of the snowpack is used in a …

Measurements And Modeling Of Snow Energy Balance And Sublimation From Snow, David G. Tarboton Jan 1994

Measurements And Modeling Of Snow Energy Balance And Sublimation From Snow, David G. Tarboton

Reports

Snow melt runoff is an important factor in runoff generation for most Utah rivers and a large contributer to Utah's water supply and periodically flooding. The melting of snow is driven by fluxes of energy into the snow during warm periods. These consist of radiant energy from the sun and atmosphere, sensible and latent heat transfers due to turbulent energy exchanges at the snow surface and a relatively small ground flux from below. The turbulent energy exchanges are also responsible for sublimation from the snow surface, particularly in arid environments, and result in a loss of snow water equivalent available …

Low Frequency Climate Variability: Understanding The Rise And Fall Of The Great Salt Lake, Michael E. Mann, Upmanu Lall, Barry Saltzman Jan 1994

Low Frequency Climate Variability: Understanding The Rise And Fall Of The Great Salt Lake, Michael E. Mann, Upmanu Lall, Barry Saltzman

Reports

Connections between the Great Salt Lake (GSL) volume (V) and large-scale climate variations are developed through an analysis of the time series of the month-to-month differences in V (change in V), local precipitation and streamflow, and gridded U.S. sea level pressure and global temperature data. We isolate decadal and secular mdoes of cliamte variability that are coherent with change in V variations. The decadal variations results from a low-frequency north-south shifting of storm tracks which influence winter precipitation. These variations describe nearly 18% of the interannual variance in change in V, while the secular trend accounts for only ~1.5%. The …
