Determining How Increasing Precipitation Intensity Will Impact Rangelands In Utah., Karen H. Beard, Andrew Kulmatiski

Browse all Datasets

As the atmosphere warms, precipitation events become larger, but less frequent. Yet, there is fundamental disagreement about how increased precipitation intensity will affect vegetation. Walter’s two-layer hypothesis and experiments testing it have demonstrated that precipitation intensity can increase woody plant growth. Observational studies have found the opposite pattern. Not only are the patterns contradictory, but inference is largely limited to grasslands and savannas. We tested the effects of increased precipitation intensity in a shrub-steppe ecosystem that receives >30% of its precipitation as snow. We used 11 (8 m x 8 m) shelters to collect and redeposit rain and snow as …

The Water Entry Of A Sphere In A Jet, Nathan B. Spiers, Jesse Belden, Zhao Pan, Sean Holekamp, George Badlissi, Matthew Jones, Tadd T. Truscott

Mechanical and Aerospace Engineering Faculty Publications

The forces on an object impacting the water are extreme in the early moments of water entry and can cause structural damage to biological and man-made bodies alike. These early-time forces arise primarily from added mass, peaking when the submergence is much less than one body length. We experimentally investigate a means of reducing impact forces on a rigid sphere by placing the sphere inside a jet of water so that the jet strikes the quiescent water surface prior to entry of the sphere into the pool. The water jet accelerates the pool liquid and forms a cavity into which …

Impact Of Bubble Baths On Stainless Steel Sphere Water Entry, Wesley Robinson

Physics Capstone Projects

Soap Bubbles on the water surface would seem to be an intuitive means for splash suppression, but their presence appears to be a double edged sword. We present on the water entry of hydrophilic spheres where the liquid surface is augmented by the presence of a bubble layer, similar to a bubble bath. While the presence of a bubble layer can diminish splashing upon impact at low Weber numbers, it also induces cavity formation at speeds below the critical velocity. The formation of a cavity generally results in larger Worthington jets and thus, larger amounts of ejected liquid. Bubble layers …

East Canyon Reservoir Water Intake Structure Final Environmental Assessment And Finding Of No Significant Impact, United States Department Of The Interior, Bureau Of Reclamation

The purpose of the proposed action is to authorize SWDC to build and operate facilities to deliver water to the Park City/Snyderville Basin area (Figure 1.2). The need for the proposed action is a growing demand for water in the Park City/Snyderville Basin area due to population growth and increased development of recreation facilities and vacation homes.

Richfield Field Office Planning Area - Proposed Resource Management And Final Environmental Impact Statement, United States Department Of The Interior, Bureau Of Land Management

Final environmental Impact Statements (UT)

The Proposed RMP was crafted primarily from the Preferred Alternative presented in the DRMP/DEIS (Alternative B) and includes other decisions within the range of alternatives (Alternatives N, A, C, and D) in response to public comments and internal review. The No Action Alternative (Alternative N) reflects current management. The BLM has removed the DRMP/DEIS Alternative B (Preferred Alternative) from the PRMP/FEIS. The other DRMP/DEIS Alternatives (Alternatives N, A, C, and D) and analyses are carried forward in the PRMP/FEIS only for comparative purposes and to correct some mistakes that were identified during the public comment period.

Reclamation: Managing Water In The West, Steinaker Reservoir Normal Water Surface Elevation Increase Final Environmental Assessment And Finding Of No Significant Impact, U.S. Department Of The Interior, Bureau Of Reclamation, W. Russ Findlay

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

This document is an environmental assessment (EA) of the proposal to raise the normal water surface elevation from 5517.8 feet above mean sea level (msl) to 5520.5 msl for Steinaker Reservoir in Uintah County, Utah. The Uintah Water Conservancy District (UWCD) has requested Bureau of Reclamation (Reclamation) authorization for this action. The Steinaker State Park, managed by the Utah Division of Parks and Recreation, maintains several campgrounds, an entrance station and other associated buildings and associated infrastructure. Modifications or relocations of some of these facilities would be needed in conjunction with an increase in the reservoir’s normal water surface elevation.

Final Environmental Assessment And Finding Of No Significant Impact For The Proposed Safety Of Dams Modifications And Bridge Reconstruction, Provo Area Office, Upper Colorado Region, Bureau Of Reclamation, U.S. Department Of Transportation, Utah Division, Federal Highway Administration, U.S. Department Of The Interior

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

The Bureau of Reclamation, Provo Area Office (Reclamation) proposes to replace the concrete spillway structure at Scofield Dam, the principal feature of the Scofield Project. This construction project would be completed under the Safety of Dams (SOD) Act of 1978 (Public Law 95-578, as amended). The proposed SOD modifications would correct safety deficiencies of the dam without affecting the purpose, or benefits of the dam. Reclamation also proposes to replace the existing gate house at its current position on the crest of the dam. This building is in poor condition and would be replaced with either a new concrete structure …

An Invasive Species Assessment Protocol: Evaluating Non-Native Plants For Their Impact On Biodiversity, Version 1, Larry E. Morse, John M. Randall, Nancy Benton, Ron Hiebert, Stephanie Lu, Natureserve

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

NatureServe, in cooperation with The Nature Conservancy and the U.S. National Park Service, developed this Invasive Species Assessment Protocol as a tool for assessing, categorizing, and listing non-native invasive vascular plants according to their impact on native species and natural biodiversity in a large geographical area such as a nation, state, province, or ecological region. This protocol is designed to make the process of assessing and listing invasive plants objective and systematic, and to incorporate scientific documentation of the information used to determine each species’ rank. NatureServe’s methodology has previously included assessments of the conservation significance of native species; this …

Due to the large volume of comments, comments and responses in this section occur in several forms. Where a "summary comment" is indicated, it is a paraphrasing of many individual comments having the same basic context. A "summary response" therefore responds to all who commented in like fashion. Where a "comment" is indicated, normally this is a singular comment in the words of the person who commented. The "response" directed toward that individual comment. In some instances, a general response is given to a series of individual comments.

Final Environmental Impact Statements (WY)

In 1990, a Winter Use Plan was completed for Yellowstone National Park (YNP), Grand Teton National Park (GTNP), and the John D. Rockefeller, Jr., Memorial Parkway (the Parkway). In 1994 the National Park Service (NPS) and U.S. Forest Service began work on a coordinated interagency report on Winter Visitor Use Management. This effort was in reaction to an earlier than expected increase in winter use. The 1990 Winter Use Plan projected 143,000 visitors for the year 2000. In 1992-93 winter use in YNP and GTNP exceeded this estimate.
