Effects of Climate Change on Water Quality
This research explores the potential effects of climate change on the quality of waters in lakes. Temperature and dissolved oxygen were considered the primary water quality variables due...

Instream Flow Strategies for Operation of the Federal Central Valley Project
Federal Central Valley Project (CVP) operations and policies of reservoir storage and river releases for fish and wildlife protection and restoration are discussed. Prescribed strategies...

Modeling Temperature Impacts on Salmon Survival
Among research goals at the University of California-Davis are the development and application of mathematical models to study water quality impacts on threatened and endangered species....

Evaluation of the Pagosa Springs Geothermal Reservoir and Implications of Potential Additional Reservoir Development
The Town of Pagosa Springs is located 280 miles from Denver on the north bank of the San Juan River in southwest Colorado as shown on the Index Map, Some time before 1920 the first well...

Computer Applications in Liquefaction Analysis
This paper discusses the applications of total and effective stress based computer programs for liquefaction analysis. A total stress based computer program, SHAKE in conjunction with...

Blast Densification of a Thick, Loose Debris Flow at Mt. St. Helen's., Washington
Numerous debris flows occurred during the 1980 eruption of Mt. St. Helen's in Washington State. The proposed location of Bridge 12 over Coldwater Creek along State Route 504 is underlain...

Field Test of Thermal Precompression
A new concept for improvement of soft ground using moderate heating to control post-construction settlement is presented. The long-term creep behavior of a peat is presented based on laboratory...

Vibration Induced Settlement From Blast Densification and Pile Driving
This paper describes settlement and vibration environments produced by two construction activities, blast densification and pile driving. Blasting is of interest because of the significant...

Coastal Eutrophication and Temperature Variation
A 3-D hydroecological model has been developed to simulate the impact of climate-change-induced daily temperature variation on coastal water quality and eutrophication. Historical daily...

Flocculation Kinetics Using Fe(III) Coagulant to Coagulate Kaolin Clay in Water: Effects of Temperature
Flocculation kinetics using ferric nitrate as a coagulant to coagulate kaolin clay in water was examined using several experimental factors. Both the particle size distribution data obtained...

Thermally Enhanced Bioremediation of a Gasoline-Contaminated Aquifer Using Toluene Oxidizing Bacteria
The combined application of steam injection and vacuum extraction has proved to be very effective for the in situ remediation of a gasoline contaminated aquifer. It is expected that the...

Testing Turbine Aeration for Dissolved Oxygen Enhancement
During August of 1993 the Bureau of Reclamation tested turbine aeration for dissolved oxygen (DO) enhancement at Deer Creek Powerplant near Provo, Utah. This test required a variety of...

The Great Lakes Forecasting System: An Overview
The Great Lakes Forecasting System is a full three-dimensional model-based system designed to make regularly scheduled predictions of the physical status of each of the Great Lakes. Due...

GLFSVIEW - GLFS Product Viewing Application
GLFSVIEW is a menu-driven Visual Basic application running under MicroSoft Windows. This application allows quick downloading, browsing, printing and display of two-dimensional data maps...

Short-Term Forecasts for Lake Erie
Short-term forecasts for Lake Erie were generated by coupling a mesoscale atmospheric prediction system with a lake forecast system. The modeling systems used were The Pennsylvania State...

Hydro Plant Research Data Acquisition System
The Colton Hydroelectric Development, located on the Raquette River in the northwestern part of New York State, is the site of a two year research project to test the use of heated trashracks...

Design and Testing of Two Ice-Preserving Winter Lake Aeration Systems
As part of an effort to achieve ice-preserving lake aeration for winterkill prevention, two non-mixing lake aeration systems were designed and field tested. Each creates a fish refuge...

Seismic Retrofitting: Spending to Save
Seismic retrofitting work is most often concerned with saving lives. But in cases of infrastructure, or historic structures, saving the structure, and making sure that it can operate after...

Fire Testing of Shotcrete Samples in a Small Furnace
The fire resistance behaviour of 8 shotcrete samples were investigated in a laboratory furnace applying ISO 834 standard test. Shotcrete was applied on 20 to 30 cm thick granite slabs...

Probabilistic Analysis of Faulting Associated with Earthquakes for Nuclear Waste Repositories
The probabilistic analysis of seismogenic faulting follows the same general methodology as the more common seismic hazard analysis for shaking. The main difference lies in the influence...
