Aggregation and Consolidation of Phosphatic Clays
The consolidation behavior of aggregated phosphatic clays has been investigated using a bench scale centrifuge. It was determined that aggregation of the clays with phosphogypsum, a waste...
Tidal Inlet Sand Transport in Rollover Pass, Texas
For Rollover Pass, which is a man-made, artificially stabilized tidal inlet located on the upper Gulf Coast of Texas, the magnitude of the net sand transport through the Pass was estimated...
Thermal Plume Model for Demonstrating Compliance
A numerical model that simulates the discharge of heated water from a multiport line diffuser to a thermally stratified, flowing environment was developed. The model solves the conservation...
Numerical Modelling of Bed Evolution in Braided Channel Systems
The overall modelling approach adopted is based on an assumption of quasi-steady flow. The numerical algorithm is based on a split-operator approach, in which the flow energy equation,...
Exfiltration Trench Design as Part of a Stormwater Management Plan
The paper discusses a program structured to assist the design consultant or the agency reviewer by means of a menu driven format. A flood routing microcomputer program developed by the...
Embankment Overtopping
Embankment overtopping and dam safety are major concerns of civil engineering and the general public. Very little is known about overtopping events and much less has been published or...
An Infiltration Based Runoff Model For Use With a Design Store
The feasibility of using an infiltration approach for routine runoff prediction has become a reality with the development of approximate infiltration models based on physical principles...
Electronic Worksheet Applications in Hydrology and Hydraulics
Spreadsheet software packages are available for virtually all micro computers in use today. Although they are quite often thought of as business tools, their usefulness as engineering...
Automated Measurement of Soil/Water Properties
An automated data-acquisition system was constructed to permit continuous operation of laboratory equipment. The apparatus was used to monitor flow through fine-grained, 'undisturbed'...
Design and Calibration of a 200-Foot Model Irrigation Border with a Computer Controlled Infiltrating Bed
A physical model of an irrigation border was constructed using a 200 ft long by 2. 5 ft wide tilting flume with a 3. 5 inch deep infiltrating gravel bed. The border was partitioned into...
Centrifugal Abrasion-Resistant Pumps in Intermediate Length Pipeline Systems
The success of long-distance slurry pipelines is in many cases dependent on careful preparation of the solids prior to transport. Positive displacement pumps are employed. However, for...
Recent Developments in Hydrologic Instrumentation
The availability of space-age materials and implementation of state-of-the-art electronics is making possible the recent developments of hydrologic instrumentation. Material developments...
Development of a Practical Method Simulating Oil Spill Migration (OSPIM) in Soils
Many ground-water modeling studies can be performed on currently available microcomputers. The greatest problem associated with the proliferation of ground-water modeling software for...
Ground-water Modeling on Small Computers: Past, Present, and Future
The paper reports on research that concerns the possible development of numerical models being able to simulate practical cases of Oil Spill Migration (OSPIM) in soils. Such models can...
Unique Considerations in the Detroit DPM Foundation Design
Foundation design for the guideway of Detroit's Downtown People Mover (DPM) was influenced by a variety of unique considerations. Severe loading conditions were created by...
An In-Plane Finite Element Model for Brick Masonry
A finite element model for brick masonry is reported. The model takes account of non linear deformations and progressive local failure. The failure may occur in the joints alone or in...
Behavior of Cavity Masonry Walls Under Out-of-Plane Lateral Loading: An Analytical Approach
In this paper, a finite element model is used to analyze cavity walls in an attempt to understand their complex behavior and to evaluate the adequacy of the assumptions embodied in the...
Shear Design of Masonry Walls
The paper presents a summary of a research project carried out at the Swiss Federal Institute of Technology Zurich to develop a design method based on the ultimate strength of masonry...
Wall/Floor-Slab Interaction in Brickwork Structures
The paper summarises the results of three series of tests on sections of brickwork structure carried out with a view to determining the characteristics of wall/floor slab joints in terms...
Shear Stresses in Composite Masonry Walls
The behavior of composite masonry walls subjected to inplane loads is a subject that has received little attention during the last few years. The small amount of experimental and analytical...
