Tropic And East Fork Irrigation Company, Tropic Ditch Replacement Project, Environmental Assessment, Bureau Of Reclamation, Provo Area Office

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

The purpose of this project is to reduce the amount of salt entering the Paria River and ultimately the Colorado River. One way to reduce the amount of salt reaching the Colorado River is to eliminate seepage from the historic Tropic Ditch. The Bureau of Reclamation, Provo Area Office has proposed funding for the project under the Colorado River Salinity Control Program. In addition to reducing the amount of salt loading, the project would also conserve water lost to evaporation and seepage.

The purpose of this Environmental Assessment (EA) is to analyze the potential environmental consequences of the proposed construction …

Micro-Structural And Phase Configuration Effects Determining Water Content: Dielectric Relationships Of Aggregated Porous Media, J. M. Blonquist, Jr., Scott B. Jones, I. Lebron, D. A. Robinson

Plants, Soils, and Climate Faculty Publications

Many porous media in which we determine water content are aggregated and characterized by a dual-porosity pore network, composed of interaggregate pores and intra-aggregate pores. This paper reports sample-scale permittivity measurements made in four stable aggregate media with dual porosity. Results indicate two distinct dielectric responses depending on whether the aggregates are surrounded by water or air. We relate transitions in the permittivity response to the water retention characteristic (WRC), showing that after the interaggregate pores have drained, the slope of the water content–permittivity relationship is significantly reduced (permittivity values ranging from 5 to 7). The hydraulic critical water content …

Record Of Decision: Operation Of Flaming Gorge Dam Final Environmental Impact Statement, U.S. Bureau Of Reclamation

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

The Bureau of Reclamation (Reclamation) has completed a final environmental impact statement (EIS) on the operation of Flaming Gorge Dam. The EIS describes the potential effects of modifying the operation of Flaming Gorge Dam to assist in the recovery of four endangered fish, and their critical habitat, downstream from the dam. The four endangered fish species are Colorado pikeminnow (Ptychocheilus lucius), humpback chub (Gila cypha), razorback sucker (Xyrauchen texanus), and bonytail (Gila elegans). Reclamation would implement the proposed action by modifying the operations of Flaming Gorge Dam, to the extent possible, to achieve the flows and temperatures recommended by participants …

Threats To Water Supplies In The Tropical Andes, Raymond S. Bradley, Mathias Vuille, Henry F. Diaz, Walter Vergara

Raymond S Bradley

Climate models predict that greenhouse warming will cause temperatures to rise faster at higher than at lower altitudes. In the tropical Andes, glaciers may soon disappear, with potentially grave consequences for water supplies.

Towards An Art And Science Of Decision Aiding For Water Management And Planning: A Participatory Modelling Process, Katherine A. Daniell, Ian White, Nils Ferrand, Alexis Tsoukias, Stewart Burn, Pascal Perez

SMART Infrastructure Facility - Papers

Planning and management of water resources are faced with increasingly high levels of complexity, uncertainty and conflict. Traditional technical and top-down management strategies have proved inadequate, forcing a move to more "integrated" forms of management, planning and decision making that can include stakeholders and communities, as well as technical experts and policy makers. These integrated forms of management require not only good technical or scientific ability, but a range of "art-like" skills including communication, creativity and the capacity to acknowledge and integrate diverse points of view. However, processes designed to aid such inter-organisational or multi-stakeholder decisionmaking are rare and in …

Ocean Warming And Freshening In The Northern Gulf Of Alaska, Thomas C. Royer, Chester E. Grosch

CCPO Publications

Water column temperatures on the shelf in the northern Gulf of Alaska have increased more than 0.8 degrees C and vertical density stratification has increased since 1970 near Seward, Alaska throughout the 250 m depth. This high latitude marine system has low water temperatures, high rates of precipitation, glacial melting, high wind speeds and high rates of biological productivity. A more than 300 km alongshore shift ( locally westward) of isotherms is suggested. The observations are consistent with a conceptual ocean-atmosphere circulation model that employs coastal freshwater discharge, glacial ablation and wind forcing. Positive regional feedback mechanisms accelerate the discharge …
