Predicting Hydrologic Impacts of a Severe and Sustained Drought on the Colorado River Basin
We investigated the impacts of a severe and sustained drought (SSD) on the hydrology of the Colorado River Basin. The simulation was carried out using the Colorado River Network (CORN)...
Activity Based Costing in Water Resources Management
This paper examines the relatively new accounting tool, Activity Based Costing (ABC), and describes its potential application in water resources planning, management, and operations. The...
Technical Understanding in Successful Environmental Negotiations
Scientists at the National Ecology Research Center conducted a series of case studies of consultations concerning the environmental conditions to be included in Federal Energy Regulatory...

CAD for Small Hydro Projects
The quest to reduce design costs and improve design quality by raising productivity is familiar to every manager and designer. This article examines how CAD can play a role by examining...
Solar Stretch
Extrapolating from structural work with textile or metal membrane roofs to cover silos, assembly halls and sports stadia, Schlaich, Bergermann and Partners, a structural engineering firm...
Case Storage of Planning Knowledge for Power Plant Construction
Schedulers consider a variety of constraints when they analyze a project to schedule the construction work for it. Often they will start from some schedule that they recall from a previous...
Microworlds for Learning Through Inquiry
We discuss several computer-based environments to support learning through inquiry, called microworlds, including two focused on steam power plant operation and electronic troubleshooting....
An Interactive Computer Code for Generations of Artificial Earthquake Records
A new interactive computer code is presented in this work for the calculation of artificial earthquake records that comply with any arbitrarily specified target response spectra or power...
An Overview of the Analysis and Design Techniques Used on the Main Tunnels of the SSC
Sophisticated numerical analysis and design techniques were devised for the Supercollider in order to produce a design which closely reflected the constraints of the construction processes,...
Prediction of Ground Deformations Due to Excavation-Application to Tunnel Lining Design in Weak Rock
Prediction of ground deformations due to excavations is simulated by three dimensional non-linear finite element analyses. It considers various in-situ ground stress levels, excavation...
Three Dimensional Simulation of Progressive Tunneling Process for Lining Design of Intersecting Tunnels in Soft Rock
This paper presents the results of the state-of-the-art three-dimensional nonlinear finite element modeling of progressive tunneling process and its comparison with field data. Reasonable...
Settlement Analysis of Landfill Liners over Deep Mined Areas
Tensile strains due to differential settlement from past mining activities were evaluated for a landfill liner. The landfill cell encompasses 20 acres and is located on a subsurface profile...
Rate of Settlement of Silt Alluvium at Trojan
Settlements of 1.83 m have been observed at the switchyard of the Trojan Nuclear Power Plant over a 22-year period since 1970. Rockfill had been placed on the site, a flood plain of the...
Strain Measurement on the Runner of a Hydroelectric Turbine
Twelve strain gages were installed on the 10-m-diameter runner of Unit G-23 (700 MW) at Grand Coulee Dam, Third Powerhouse. The gages were located on both the pressure and suction sides...
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...
Pressure-Time Flow Rate in Low Head Hydro Plants
Very few methods are accepted for measuring the flow in the large intakes typical of low head, run-of-the-river hydro plants. These intakes are characteristically short, non-uniform, non-prismatic,...
On the Erodibility of Rock and Other Earth Materials
An outline of a new method to determine the erodibility of rock and other earth and engineered earth material is presented. The method quantifies the relative capacity of the boundary...
Scada System Requirements for Optimum Pumping
In order to minimize the cost of electric energy for pumping water through its distribution system, a computer program was developed to schedule the operation at eight pumping stations...
Integrated Planning for International River Basin
The integrated development of the Vardar/Axios Basin includes a system of projects scheduled to meet the needs and aspirations of Yugoslavia (in particular, the former Socialist Republic...
