Seismic CPT to Measure In-Situ Shear Wave Velocity
A new test, called the seismic cone penetration test (SCPT) is described. A small rugged velocity seismometer has been incorporated into an electronic cone penetrometer. The combination...
Relationships between Shear Wave Velocity and Depth of Overburden
Relationships between in-situ shear wave velocity and depth of overburden have been derived for various Quaternary age soils encountered primarily in Southern California. The geotechnical...
Arctic Foundation Selection: A Decision Matrix
An idealized matrix diagram is presented of the decision making process involved in determing an economic Arctic foundation type that is best suited to the proposed above-grade structure....
Case Histories: Evaluation of Drilled Pier Integrity by the Stress Wave Propagation Method
The Stress Wave Propagation Method (SWPM) was used to nondestructively investigate the integrity of straight-shaft drilled pier foundations at two sites in the Denver, Colorado area. Drilled...
Simulation of Rock Fracture with the 3-D SHALE Code
The 3-D SHALE code simulates the propagation of stress waves and the occurrence of fracture in brittle solids. The physical models and numerical methods in this code are similar to those...
Noise and Air Blast from Construction Blasting
Noise generated by construction blasting differs from other construction noise because of its frequency content. The audible high frequency portion is accompanied by a non audible, lower...
Hammering Out a New RCRA
Recent amendments to the Resource Conservation and Recovery Act (RCRA) add thousands of new waste generators and many new wastes to the list of those to be regulated. Some say RCRA is...
Modeling a Water Distribution System
Problems encountered in modeling the water distribution system for the City of Norwich, NY are discussed and the procedures used to solve each problem are described. The interpretation...
Complications in the Design and Analysis of Small Water Distribution Systems
The design and operation of small treatment and distribution networks can sometimes be more complicated than the design of large metropolitan systems. More often than not, the use of standard...
Modelling Complex Water Distribution Systems
A program previously used for the analysis of hundreds of water distribution systems was successfully modified to provide the features needed for the extended simulation of large complex...
Practical Optimization of Looped Water Systems
This paper describes one tool that might be part of a package to assist a design engineer in sizing pipes, determining ideal locations for booster pumps and their heads, determining heads...
Understanding Secondary Clarifier Behavior
The author has developed a graphic procedure for analyzing the hydraulic behavior of settling tanks. Data have been used in numerous cases to devise low cost in-tank and external improvements...
Detection of Leakage Through Subsurface Barriers Using Guided Acoustic Waves
The primary method for preventing hazardous liquid and leachates from entering the groundwater is the use of a physical barrier. These barriers are susceptible to a number of mechanisms...
Coast of California Storm and Tidal Waves Study: A Regional Coastal Zone Monitoring Program
An integral aspect of the Coast of California Storm and Tidal Waves Study (CCSTWS) was the implementation of a four year comprehensive regional coastal zone monitoring program in 1983....
After Action Report 1983 California Coastal Storms
The winter of 1982-1983 saw some dramatic changes in the worldwide weather patterns that have been attributed to the anomaly known as El Nino. During that winter California was attacked...
Coastal Management Problems in the United Kingdom
Five case-studies from the East coast of England illustrate some of the obstacles facing more enlightened coastal management in the United Kingdom. All the examples demonstrate unsatisfactory...
Prior Planning for Post-Hurricane Reconstruction
Planning for hurricane emergencies has focused upon the period immediately before and after the storm's arrival, emphasizing evacuation and disaster relief. Mitigation of...
Hurricane Evacuation Studies, an Overview of Major Analyses
The purpose of this manuscript is to present the methods employed, the types of data generated and the interrelationships of the major analyses conducted for a hurricane evacuation study....
Foreshore Treatment as a Method of Coastal Protection
This paper describes the damages sustained by a small section of the Vancouver, British Columbia coastline during the passage of a storm in December, 1982. This stretch of protected coastline...
Ebb-Tidal Deltas and Barrier Island Morphology
Offshore depositional features such as ebb-tidal deltas may have significant and perhaps controlling influence on barrier island morphology. These features serve three primary functions....
