Lead Isotopic Composition of Paleozoic and Late Proterozoic Marine Carbonate Rocks in the Vicinity of Yucca Mountain, Nevada
Paleozoic and Late Proterozoic marine carbonate rocks (limestones, dolomites, and their metamorphic equivalents) cropping out in the vicinity of Yucca Mountain contain lead with an isotopic...
Isotope-Geochemical Investigations of Volcanic Rocks in the Vicinity of the Radiochemical Plant Mayak (Russia)
Russian programmes on radioactive waste management consider a possibility to organize an underground laboratory and subsequently an underground repository for intermediate- and high-level...
Mercury Porosimetry Studies on a Natural Fracture
Mercury porosimetry techniques were used to study the effects of stress on the capillary pressure characteristics of a single natural fracture. In addition, permeability measurements were...
Small-Scale Behavior of Single Gravity-Driven Fingers in an Initially Dry Fracture
Experiments investigating the behavior of individual, gravity-driven fingers in an initially dry, rough-walled analog fracture are presented. Fingers were initiated from constant flow...
Modeling Gravity-Driven Fingering in Rough-Walled Fractures Using Modified Percolation Theory
Pore scale invasion percolation theory is modified for imbibition of wetting fluids into fractures. The effects of gravity, local aperture field geometry, and local in-plane air/water...
Expert System for the Preloading Method of Ground Improvement
Design practice of the preloading method, which is one of the ground improvement techniques, applied for the hydraulic fill area includes quite complicated problems, especially when draining...
Project Performance: Ocean City, Maryland Beach Nourishment
Detailed monitoring of the performance of a two-phase beach nourishment project has provided valuable information on beach fill behavior and long-term response of a beach fill to prevailing...
Performance of Beach Nourishment at Hilton Head Island, South Carolina
Between May and August, 1990, approximately 2.34 million cubic yards of sand were placed along 35,000 feet of the Atlantic shoreline of Hilton Head Island, South Carolina. The project...
Beach Fill Performance at the Lido Beach, Florida, Groin
Lido Beach on the Gulf of Mexico in Sarasota, Florida traditionally has been used as a placement area for sand dredged from the adjacent New Pass federal navigation project. At the end...
Optimization of Beach Fill Transitions
Accentuated erosion or end loss by excessive longshores and transport occurring at abrupt lateral terminations of beach fills can compromise a fill's shore-protection functioning and longevity....
Revere Beach and Point of Pines, Massachusetts, Shore Front Study
This paper describes a study conducted by the Coastal Engineering Research Center (CERC) to determine the degree of storm protection provided by an existing coarse beach fill at Revere...
Simulation of Beach Fill Response to Multiple Storms, Ocean City, Maryland
The beach fill project constructed over 1988-1991 at Ocean City, Maryland, includes nearshore wave and water-level measurements and high-accuracy beach profile sea-sled surveys performed...
Beach Morphology Analysis Package (BMAP)
This paper describes a newly developed personal computer software analysis package called BMAP, which stands for 'Beach Morphology Analysis Package.' The BMAP is an integrated set of beach...
The Profile Volume Approach to Beach Nourishment
The purpose of this paper is to outline a design approach to beach nourishment that emphasizes profile volumes. The advantages and disadvantages of the method are discussed and related...
A Man-Machine Partnership for Map Production: An Application of Image Classification and Auto-Vectorization in Charting Coastlines
The semi-automatic production of coastal area maps through computer processed digital images is described. Two sources of digital imagery were addressed: satellite and aircraft mounted...
The Saint Lawrence River System, Atlantic Coast of Qu?bec
At the 1:250,000 scale, Quebec has 13 773 km of coasts, 6 772 km of which belong solely to the Saint Lawrence River System. This system can be divided into six portions: river, limnetic...
Testing Outlet Works Gates and Valves at USBR Dams Under Unbalanced-Head Conditions: Tieton Dam Unbalanced-Head Gate Test
The Tieton Dam outlet works installation geometry is the most common type used in U.S. Bureau of Reclamation (USBR) earthfill dams. An emergency guard gate is located in a gate chamber...
Computer Aided Design and Cost Estimation of Gabion Lined Channels
Rivers are a dynamic part of the hydrologic cycle. Changes in discharge, flow depth, water velocity, and meander patterns contribute to this dynamic nature. As a result, portions of a...
Design of Riprap Stilling Basin for Overhanging Pipe
The rock rip-rap basin is the most common and economical method of handling the problem of scour at a pipe outlet. The advantage of the method is speed of construction, absence of the...
Use of CLSM Fly Ash Slurry for Underground Facilities
This paper presents the results of research performed in developing and using flowable fly ash slurry which falls under the classification of Controlled Low Strength Material (CLSM) as...
