Planning Implications of Urban and Rural Freeway Interchanges
Accessibility, traffic and the availability of developable land have been the volatile ingredients touching off the development explosion in the vicinity of the freeway interchanges. Zoning...

Photogrammetric Mapping of Craters from Small Explosions
The possible future use of nuclear explosives for large-scale excavation projects has led to small-scale investigation of cratering and ejecta mechanisms using chemical explosive charges....

Nuclear Excavation of a Sea-Level Isthmian Canal
The study considers the construction of a sea level canal from the Gulf of Aqaba to the Mediterranean Sea, by means of nuclear explosives. In 1956 a similar proposal was reviewed and rejected...

Simulation of Waves by an Underwater Explosion
The properties of water waves produced by underwater explosions were studied in a test basin where the underwater disturbance was simulated by means of a rapidly withdrawn or immersed...

Shock Spectra Subsurface Nuclear Explosions
Equations are given for computing vertical and horizontal radial ground-stock spectra from an underground nuclear explosion. Parameters required are the yield of the explosion, the slant...

Knowledge of Sedimentation in Urban Environments
The population explosion, coupled with technological progress of the last century, has created megalopolis. Urbanization-suburbanization of America has changed the hydrology of affected...

Comparative Radioactivities from Nuclear Excavation
The chief potential value of nuclear excavation is in reduced initial cost. In addition to economic factors, however, practicality and safety of the nuclear method must be assessed for...

Aquatic Plants in Maryland - A Growing Menace
The rapid increase in the population of the Chesapeake Bay Area coupled with the almost explosive increase in tidewater-oriented pursuits has resulted in intensive development of waterfront...

Information Retrieval for Soil Engineers
Authors of soil mechanics literature must facilitate the transfer of information to others by using concise titles, writing informative abstracts giving results and conclusions, and providing...

Mud Floods Related to the Irazu Volcano Eruptions
The ash erupted by the Irazu Volcano in Costa Rica during its period of explosive activity, 1963–65, destroyed the vegetation of the Reventado River upper basin* The direct consequence...

Boiler Column Straightening Upper Load Conditions (1965 Power Division Specialty Conference, in Denver Colorado)
An accidental boiler explosion that occurred at Southern California Edison Company's Alamitos Steam Station provided engineers with an opportunity to test their design under...

Particle-in-Cell Method in Shock Propagation Problems
The paper considers a particle-in-cell approach for the analysis of high velocity impact problems in which large motions preclude the practical use of either a purely Lagrangian or purely...

Soil Surface Compaction with a Foam-Type Explosive
A proposed new method for soil surface compaction based on the principle of pressure waves as a source of energy is described. This method, which has been termed the foamed propellant...

Water Waves Generated by Underwater Explosions

Boiler Column Straightening Under Load Conditions

Educational Requirements for Water Resources Engineers
Water resource development is the provision of an ample supply for all purpose of high quality water at a reasonable price. The explosion in water use and population is demanding the continued...

Nuclear Excavation of a Sea-Level Isthmian Canal
Data on high-explosive and nuclear cratering events are combined with 1947 Route Surveys (Panama Canal Company) to estimate the number and yield of the nuclear devices required to excavate...

Densification of Soils by Explosive Vibration
Densification is compaction applied to unlimited depths from the surface. Densification allows building on granular soils with original bearing values below minimum, reduces or eliminates...

Model Predictions of Fracture Due to Explosions
Evidence indicates that small model systems using the same material, same explosive, and similar geometry give good quantitative predictions of strains in a number of rocks, but only qualitative...

Yielding at Varying Loads Rates
Yield strength of several aluminum alloys were determined experimentally under rates of stress application ranging from 4×105 psi/sec to 19×106...
