Quantifying Florida's Coastal Storm Wave Susceptibility
A simple computer model capable of describing potential storm wave inundation and damage along Florida's sandy beaches is described from first principles. Model STORMWAVE...
Measurement and Use of Shear Wave Velocity for Evaluating Dynamic Soil Properties
Geotechnical engineers have recognized in the past decade that shear wave velocity is a basic soil property and have begun to use it to characterize sites for many uses. Most notable has...
Floating Bridge for 100 Year Storm
In 1979 the west half of the Hood Canal Floating Bridge, built in 1960, in Seattle broke up and sank during a storm that lasted eight hours with winds of 80 mph and gusts over 100 mph....
Designing for Residual Flooding
Flood control projects should incorporate designs and responses for flooding of the protected areas due to exceedance, overtopping, or failure of the features. Design strategies for levees,...
A Two-Dimensional Numerical Model of Thermal Discharges in Coastal Regions
This paper describes a two-dimensional numerical model of thermal discharges in coastal regions. The model uses potential flow theory to calculate the ambient velocity field of the coastal...
Open Channel Flowrate Measurement Using Multipath Acoustic Flowmeters
Recent acoustic flowmeter developments have improved the applicability and accuracy of the multipath acoustic measurement technique. Accuracy, hardware cost and calibration cost can be...
Boundary Shear Stress in a Meandering Channel
Longitudinal and transverse velocity, bed shear, and water surface elevation were studied in a fixed-bed, meandering, laboratory channel with naturally varying, non-prismatic cross sectional...
Numerical Models for Two-Dimensional Surface Runoff
Numerical models for surface runoff in watersheds having two-dimensional or horizontally varying topography are presented. Two finite element methodologies, a standard Galerkin and a streamline...
Response of Floating Structures in a Directional Sea
A finite element numerical model is presented to predict the behavior of long floating structures in a multi-directional sea. A follow up numerical model analyzes an important but mostly...
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...
Secondary Circulation Data Acquisition System
A computerized field data collection system was developed for a project investigating secondary circulation in natural rivers. The instrumentation includes a Commodore mini-computer with...
Hydraulics of Broad Crested Weirs
The paper presents a general, basic discussion of the title subject. It begins with a definition for the broad crested weir and analytical concepts. Subjects covered subsequently include...
Velocity Distribution Factor Constraints
It has been customary to introduce the velocity distribution factors alpha and beta into the energy and momentum equations so as to avoid the integration associated with variations in...
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...
