Improved Computer Simulation of 3D Wind Flow Around a Building
A two-layer method combining the k-? model with the one-equation model near the wall has been tested in computing the wind conditions around a cubic building. In contrast with the simple...

Random Vortex Models in Wind Engineering
Random vortex methods are Lagrangian particle-based numerical simulation schemes especially appropriate for Wind Engineering simulations. Vortex methods do not suffer from numerical diffusion...

Empirical Performance Comparison for Symbolic and Subsymbolic Learning Systems
The paper gives a description of a comparative study of two learning systems based on symbolic and subsymbolic learning. The two systems' performance was analyzed using the overall empirical...

Estimating Sediment Relative Density Using an Impact Core Sampler and Wave Equation-based Pile Analysis
This paper presents a case history in which soil sample drive resistance was modeled with a wave equation-based pile analysis computer program to estimate in situ sediment relative densities...

A Knowledge-Based Computer System for Financial Wind Risk Management
This paper presents the results of a sponsored applied research project conducted by a multi-disciplinary team to integrate state-of-the-art methods in wind and collateral (e.g., surge,...

The Tip Displacement of Drilled Shafts in Sands
The design load of large diameter drilled shafts is determined so that the settlements do not exceed the values associated with the ultimate and serviceability limit states. Based on the...

Computing Two Dimensional Flood Propagation with a High Resolution Extension of McCormack's Method
McCormack's method, as applied for solving the bidimensional de Saint Venant equations is enhanced with the aid of the theory of Total Variation Diminishing (TVD) schemes in order to obtain...

Modelling of Flood Wave Propagation Over Flat Dry Areas of Complex Topography in Presence of Different Infrastructures
After a description of the general equations which govern the propagation of a 2D flood wave (shallow water equations), a review of the scientific publications on the integration of their...

New Methods for Modelling Dam-Break Wave
Recent developments in numerical analysis for hyperbolic equations have led to new methods which solve shallow water equations including complementary equations for hydraulic jumps. An...

Formation and Propagation of Steep Waves: An Investigative Experimental Interpretation
From the end of the last century, many Authors have studied experimentally the formation and the propagation of steep waves on dry flume bottom. Up to the present time, however, some aspects...

Free surface flow modelling on a complex topography
The aim of this paper is to describe the different construction stages and the validation of a free surface flow model on a complex topography. This model is based on the two dimensional...

Measurement of Turbulent Properties in a Natural System
Instruments designed to measure flow properties in stratified estuaries, lakes and oceans are reviewed. Emphasis is given to the measurement of turbulent fluxes and recent developments...

Experimental Study on Turbulent Structures in Unsteady Open-channel Flows
Turbulence measurements in unsteady open-channel flows over smooth beds were conducted accurately by the simultaneous use of two-component LDA system and water-wave gauges. In the inner...

Developing Air Concentration and Velocity Probes for Measuring Highly-Aerated, High-Velocity Flow
The U.S. Bureau of Reclamation's stepped spillway overtopping protection research program required velocity and air concentration profile data be obtained during testing in a large, 15.2-m-high...

Field Performance of an Acoustic Scour-Depth Monitoring System
The Herbert C. Bonner Bridge over Oregon Inlet serves as the only land link between Bodie and Hatteras Islands, part of the Outer Banks of North Carolina. Periodic soundings over the past...
