Estimating Earthquake Sizes in the Basin and Range Province, Western North America: Perspectives Gained from Historical Earthquakes
Thirty eight historical earthquake from the Basin and Range province were used to examine three aspects of earthquake size and behavior: 1) the maximum background earthquake, 2) earthquake...
The Truss-Beam and Space Technology
A method is presented herein to determine the dynamic characteristics of truss-beam systems for both planar and space structures. Results from this approach are compared with those of...
Meta-Site: Water Distribution System Analysis Software
Many local municipalities now require a network analysis for all proposed additions to their water distribution systems. A graphically oriented, user-friendly program is being developed...
Reliance on Structural Controls for Water Supply Protection in Urbanizing Watersheds
The watershed is the source of pollutants which can contaminate the water supply reservoir. It is far preferable to implement an affordable watershed management plan that keeps contaminants...
Numerical Modeling of the Vertical Salinity Distribution in Coastal Canals
A two dimensional (laterally averaged) numerical model of estuarine circulation has been developed for the prediction of the vertical salinity distribution in coastal canals. The model...
