Computing and Design in Structural Engineering A Practicing Engineer's Point of View
The development of the electronic computational power of the computer has been a boon to the structural engineering profession. The resulting increases in the speed and efficiency of the...
Computing in Analysis and Design in Structural Engineering Education, Practice and Registration: A View from the National Council of Examiners for Engineering and Surveying
When taking the examinations for licensure as professional engineers, computers are not allowed. The knowledge tested on the Structural Engineering examinations are discussed with a sample...
Nowcast System Development for the Straits of Florida
As part of the inaugural program for the Ocean Pollution Research Center at the University of Miami, a nowcast system is being developed for the Straits of Florida. The nowcast system...
Validation of a Continental-Scale Storm Surge Model for the Coast of Delaware
Coastal structures are designed to provide protection against various forces of nature acting in the coastal zone. Structures such as seawalls are expected to provide onshore protection...
Localized Sigma Coordinates for the Vertical Structure of Hydrodynamic Models
This paper analyzes the use of localized sigma coordinates in the numerical solution of the vertical structure of coastal flows. We show, through a combination of truncation error analysis...
Analyzing Larval Fish Distributions Using Hydrodynamic and Transport Modelling
Port Moller is a major spawning ground for Pacific herring. Coincident with extensive larval sampling in the estuary, data required for simulating three-dimensional hydrodynamics and transport...
Design, Construction, and Maintenance of Relief Wells
Technical Engineering and Design Guides, as adapted from the U.S. Army Corps of Engineers, No. 3 This engineering manual provides guidance and information...
Boston's Backup Water Supply
For fifty years, Boston's sole real source of water has been the Hultman Aqueduct, but now final design is almost complete on the MetroWest Supply Tunnel, a new, larger conduit...
An Experimental and Analytical Study of the Shoreline Response to Non-Parallel Breakwaters in Oblique Waves
REsults of an experimental and analysis study single breakwaters on oblique waves are presented. Three orientations of the breakwaters are studied, those being parallel to the shoreline,...
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...
Second Order Irregular?Wave Generation in Flumes - Computation of Transfer Functions by an Asymptotic Summation Method
Recently the theory for second order irregular-wave generation (including superharmonics as well as subharmonics) has been rederived for a variety of different types of wave board motion....
Wave Transformation and Load Reduction Using a Small Tandem Reef Breakwater ? Physical Model Tests
The performance of several small reef breakwaters, and a tandem breakwater system (consisting of a reef breakwater positioned upwave from a surface-piercing main breakwater), are quantified...
The Evolution of Breakwater Design
The purpose of this paper is to present a view of the evolution of both the rubble mound and vertical faced breakwaters from the earliest design through the Iribarren and Hudson era. Determining...
Dynamic Loading of Airfield Pavements Caused by Aircraft Operations on Rough Runways
