Features of a Chevron Weir Rock Ramp
This paper presents the features of a new type of low profile grade control structure, the chevron weir rock ramp. As the name infers, the planform of the structure is in the shape of...
Rock Riprap for Grade Control
Rock chutes (riprap channels on steep slopes) are used as grade control structures to safely conduct a water flow to a lower elevation. Common procedures used for design of rock riprap...
Scour in Erodible Rock II: Erosive Power at Bridge Piers
Scour depths around bridge piers founded on erodible rock can be determined by making use of the Erodibility Index Method. This method defmes an erosion threshold by relating the erosive...
Predicting Transport of Organics through Soil Columns using Distributed Mass-Transfer Rates
A numerical model to describe contaminant transport through soil columns, including distributed mass-transfer, is developed. Both a gamma distribution and a lognormal distribution are...
Problem and Technical Solutions: The Seven Oaks Dam, Physical Elements of the Seven Oaks Dam Feature
Seven Oaks Dam is located in the upper Santa Ana Canyon approximately 1 mile from the canyon mouth. The site is 8 miles northeast of the city of Redlands in San Bernardino County on the...
Simulation of Dissolved Oxygen in Sacramento-San Joaquin Delta
A one-dimensional model has been developed to simulate water quality in a complex multi-channel estuarine system. The model utilizes a Lagrangian reference frame for transport computations....
Riprap and Concrete Armor to Prevent Pier Scour
Local scour is not a product of recent times or modern building practices. The annals of the Institute of Civil Engineers, in London, contain references throughout the 1800s and early...
Rock Foundations
This manual provides technical criteria and guidance for the design of rock foundations for civil works or other similar large military structures. It provides a minimal standard to be...
Scour Power
New prediction methods consistently calculate scour around bridge piers allowing engineers to better tailor pier design in rock and consolidated material. The leading cause of bridge failure...
Uncertainty in the Geologic Environment
from Theory to Practice
The state-of-the-art is presented with respect to analytical and design methods incorporating uncertainty in the geologic environment. Particular emphasis is placed on practical applications...
Design with Residual Materials
Geotechnical and Construction Considerations
Residual materials are in-place soil and rock like material derived from the chemical weathering of rock. The nature of residual material is a function of the type of parent material and...

The Challenge of Housing the Largest Detector
The most innovative part of the structural-civil design of the Superconducting Super Collider (SSC) is that of the underground experimental halls located alongside the 86 kilometer collider...
Concrete Shells Today
Providing high structural qualities, modern shells using experimental forms will attract new attention due to their limitless repertory. Presented is a new form of construction, instead...
Boston's Backup Water Supply
For fifty years, Boston's sole real source of water has been the Hultman Aqueduct, but now final design is almost complete on the MetroWest Supply Tunnel, a new, larger conduit...
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...
Automatic, Remote, Multiplexed Geotechnical Measurements with Time Domain Reflectometry (TDR)
Time Domain Reflectometry (TDR) has been employed successfully in geotechnical applications such as monitoring of rock mass deformation in a variety of geometries; however, required operation...
Settlement of a 15-Meter Deep Fill Below a Building
The site for a building in western Pennsylvania was undermined, with the mine base about 15 m below planned final grade. Rock above the mine was highly fractured and of poor quality, indicating...
