Stresses and Displacements in Cross-Anisotropic Soils
An analytic investigation is presented on the effect of soil cross-anistropy on surface displacements and stress distributions in a homogeneous thick soil deposit (halfspace) subjected...

Acrosswind Response of Buildings
The acrosswind response of buildings is investigated. Expressions for the acrosswind loading are developed through the use of the spatio-temporal measurement of the fluctuating pressure...

Embankment Construction: New Melones Dam
New Melones Dam, located on the Stanislaus River in central California, is a zoned earth and rockfill structure with a maximum height above foundation at embankment centerline of 637 feet...

Load Capacity of Concrete Bridge Decks
The behavior of two reduced-scale concrete bridge decks subjected to simulated wheel loads was evaluated in a series of tests. One slab was reinforced in accordance with AASHTO requirements;...

Research Needs in Marine Surveying
Research needs in oceanographic and hydrographic surveying and charting are discussed. It is suggested that the two most crucial elements which effect all measurements in hydrography and...

Politicians Are Not Technologists: Technologists Are Not Politicians
The view that there are too few engineers in the legislative branch of government is confirmed. It is argued that the lack of scientists and engineers in elected public offices creates...

Geodetic Monuments for Eccentric Property Corners
Problem areas in land information systems are identified and described and solutions are proposed. The main areas discussed include a method of equitable property taxation, replacement...

Surveying: The Profession and Its Requirements
Two definitions of surveying are discussed. The A.S.C.E. definition which is a broad definition that includes a. land surveying, b. engineering surveyors, c. cartographic surveying, aerial...

Sewer Network Routing by Dynamic Wave Characteristics
Hydraulics of unsteady flow in storm sewer networks is investigated by using a dynamic wave simulation model. The Illinois Storm Sewer (ISS) Model solves the complete dynamic equations...

Hot-Film Response and Digital Analysis in Bubly Flows
Hot film responses in bubbly flows are analyzed for the development of a digital analysis technique. It is shown that hot-film anenometry and digital data analysis techniques can be excellent...

Discharge Assessment in Compound Channel Flow
A series of laboratory tests were performed to measure the boundary shear stresses in a compound channel consisting of a main channel and associated shallow floodplains. Four different...

Columns with Semirigid Joints
The influence of realistic semi-rigid end restraint on the strength and behaviour of real steel columns is investigated. An analytical procedure is developed which includes the effects...

Groundwater Contamination due to Continuous Sources
Analytical methods are described to predict the concentrations of effluents released in a two- or three-dimensional groundwater flowfield from a point, line, plane or parallel piped source....

Numerics for Common First-Passage Problem
Numerical analysis aspects of the Kolmogorov backward partial differential equation associated with the first-passage problem of the response amplitude of a lightly damped linear structure...

Initial Pore Pressure from Vertical Surface Loads
In estimating the initial settlement of footings supported on saturated clay soils, it is necessary to evaluate the instantaneous excess pore pressure developed in the soil upon application...

Investigation of Failures
The problems associated with determining what actually happended after an unexpected instability has occurred are illustrated by case records. Examples are taken from failures of cut slopes...

Mathematical Model for Erodible Channels
A mathematical model for erodible channels is formulated, developed and tested with field data. A significant feature of the model is its ability to account for changes in both channel...

Scattering of SH Waves by Subsurface Topography
Horizontally polarized shear waves in an elastic alluvial valley of arbitrary shape perfectly bonded to a linearly elastic, homogeneous and isotropic half space are considered. The valley...

Scattering of Elastic Waves by an Alluvial Valley
Plane strain model for scattering of steady state plane waves by an elastic alluvial valley of arbitrary shape is presented. The valley is presumed to be perfectly bonded to a linearly...

Pumped Bentonitic Mixture Used to Seal Piezometers
Methods used to install the bentonite seal and sand-cement grout seal for multi-level piezometers are described. After problems developed in trying to use bentonite pellets to install...
