On Hurricane-Generated Seas
Two different situations in the relationship between wind speed and sea severity during hurricanes (and tropical cyclones) are clarified from analysis of measured data obtained by NOAA...

A Comparison of Wave Statistics in Uni- and Multidirectional Shoaling Seas
the transformation of six unidirectional and multidirectional seas propagating over a 1:25 planar beach are examined in a series of laboratory experiments. In all cases, the mean wave...

A Second-Generation Wave Model for Coastal Wave Prediction
A second-generation numerical wave model, WINDWAVE, has been developed for wave prediction in coastal regions. The modal is based on the numerical integration of the energy balance equation...

Physical Modelling of Multidirectional Waves
A sixty-segment wave generator has been used since 1985 at the Coastal Engineering Laboratory of the National Research Council (NRC) of Canada to generate multidirectional waves, and study...

Wave Run-Up and Reflection on a Permeable Sea Wall
The swash oscillation on a sloping seawall made of step-shaped concrete blocks, waves and water particle velocity in front of the seawall were measured. It was inferred that incident waves...

The Significance of Hydrodynamic Forces in Coastal Embankment Design
The dynamic forces of sea water and backfill soil acting on coastal embankment are analyzed by using a new finite-difference method. The Euler's equation and continuity equation are used...

Locking Into Success
In 1961, at Wheeler Lock in Alabama, crews with the Tennessee Valley Authority tried to incorporate an existing lock wall into a new cofferdam. A major portion of the land wall slid about...

Intentions and Credences ? An Australian Approach to Computerised Building Regulation
In the past, computer representation of building regulations has addressed a series of prescriptive requirements. Compliance with each requirement was essential and the only relationship...

Integrated Product Models
A review is made of current STEP standards efforts to develop integrated product models, using the Express language. An example of a building wall is presented, along with some general...

Macroelement Model for Shear Wall Analysis
An efficient modeling scheme for static and dynamic analysis of reinforced concrete shear walls in the inelastic range is presented. The macroelement model of the shear wall is composed...

Climate Warming and Great Lakes Management
A decision-analysis approach to determining the relevance of information on climate change for near-term Great Lakes management decisions is outlined. Simplified applications to decisions...

Coastal Eutrophication and Temperature Variation
A 3-D hydroecological model has been developed to simulate the impact of climate-change-induced daily temperature variation on coastal water quality and eutrophication. Historical daily...

Simultaneous Flow Visualization and Hot-Film Measurements
High-speed video recording of flow visualizations in the near wall region of a turbulent open channel flow was synchronized with hot-film measurements of flow velocity and bed shear stress...

Kent, Edward
In order to perform conservative scour analyses for coastal bridge sites it is necessary to develop realistic hydraulic simulations which provide worst case estimates of depth and velocity....

Stability Analysis of Rayleigh-Benard Convection in the Presence of Side Walls
The onset of laminar axisymmetric Rayleigh-Benard convection is investigated for a low-Prandtl number liquid metal in a cylindrical container, in the presence of a vertical temperature...

Boundary Shear in the Vicinity of River Banks
Some experimental data are presented concerning the distribution of boundary shear stresses in trapezoidal open channels for both inbank and overbank flows. The local shear stresses on...

Building A Barrier Wall Through Boulders
Engineers and contractors conceived a novel approach to a barrier wall at a difficult site near the Niagara River in New York State. The site had been contaminated by a chemical company...

Stiffness of Low Rise Reinforced Concrete Shear Walls
This report, Stiffness of Low Rise Reinforced Concrete Shear Walls, was prepared by the Working Group on the Stiffness of Concrete Shear Wall...

Effect of First-Story Shearwalls on Earthquake-Resistant Buildings
A Practical system for earthquake-resistant building design is described. The system utilizes Teflon sliders at the top of the first story framed shearwalls to carry a portion of the superstructure....

Damage Assessment for Reinforced Concrete Buildings with Shear Walls
This paper tries to establish the analytical method of damage assessment for R.C. buildings with shear walls before or after earthquake. Incremental nonlinear spectrum analysis, using...
