Embankment Overtopping Tests to Evaluate Damage
The paper reports on studies of embankments 6 ft high, 10 to 22 ft in crest width, and 3 ft in length, with slope varying from 2:1 to 4:1. Embankment surfaces include pavement, grass,...
Overtopping of Small Dams?An Alternative for Dam Safety
A research effort was initiated in 1983 by the Bureau of Reclamation to gain insight in the development of cost-effective modifications to small embankment dams which would enable them...
Planned Overtopping of Embankments Using Roller Compacted Concrete
Three recent projects are discussed where the economy and versatility of roller compacted concrete (RCC) were utilized to allow flood water overtopping of small to medium size embankment...
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...
Data Acquisition and Analysis of Pressure Fluctuations in Hydraulic Jumps
The paper reports on a study to procure basic data on large pressure fluctuations in hydraulic jump stilling basins. Interest in pressure fluctuations relates to: the effect of dynamic...
Water System Analysis?Modeling Hydraulics
The work described in this paper is part of the planning and design effort for expanding and improving the water supply system for St. John the Baptist Parish, Louisiana. The parish is...
Tidal Modelling on IBM Microcomputers
The finite element code, QUIET, for the simulation of two-dimensional shallow water flow has been adapted from its mainframe form for use on the IBM PC, PC/XT, or AT. The model uses of...
The Matched Artificial Dispersivity Method
The paper presents a class of models that are well-suited for microcomputing and that are based on what may be called the 'Matched Aritifical Dispersivity' method....
Explicit Finite Element Model for Long Water Waves
An explicit finite element model for free-surface flow is presented. The model is capable of simulating long waves of various orders of approximation in one and two space dimensions. The...
Transients in Empty Pipes Subject to Rapid Filling
A mathematical model was developed to simulate the pipe filling process and the pipe forces based on incompressible water column theory. The method easily accomodates appropriate boundary...
Analysis of Resonance in Pressurized Piping Systems Via a Microcomputer
In this paper a digital simulation technique for the analysis of resonance is presented that is appropriate for microcomputer applications. The model utilizes the transfer matrix method...
Quick Stroking: A Fast and Accurate Algorithm for Time-Optimal Valve Closure Synthesis
In this paper, a fast, simple, yet effective technique for valve motion synthesis is developed. This technique called Quick Stroking is applied to a practical example problem, and it may...
Flood Peak Program for Urbanizing Semi-Arid Areas
This paper describes a microcomputer program for flood peak determination based on a highly modified version of the Rational method developed by M. E. Zeller, which employs the Soil Conservation...
A Microcomputer Dispersivity Evaluation Method for Thick Aquifers
The Littoral Environment Observation (LEO) program uses volunteer observers recruited to obtain daily visual observations of such coastal variables as breaker height, wave period, direction...
Type C Fly Ash and Clay Stabilization
Because the soils onsite have a high swell potential, a 37 foot high retaining wall was designed with counterforts and was supported by pier foundations to limestone. In order to reduce...
Liquefaction Flow Failure of Silty Sand by Torsional Cyclic Tests
The use of undrained strain-controlled cyclic torsional loading of anisotropically consolidated triaxial specimens (CyT-CAU tests), is proposed for evaluating liquefaction flow failure...
Aspects of Constant Volume Cyclic Simple Shear
Data from cyclic simple shear tests comprise the foundation on which rests most of the practical applications of theoretical soil dynamics. The importance of the test derived from two...
Shear Moduli Measurements under True Triaxial Stresses
The effect of state of stress on the shear wave velocity and shear modulus of a dry sand was examined. Testing was performed in a large-scale triaxial device in which cubic soil samples...
Seismic Design of Concrete Faced Rockfill Dams
The results of analytical studies of the stability of the slopes of concrete-faced rockfill dams under different levels of earthquake shaking are presented and used to propose desirable...
Coefficient of Variation of In Situ Tests in Sand
For a research project on the behavior of piles in sand for the United States Geological Survey and the Federal Highway Administration, ten sites were selected where detailed load tests...
