The Formation of a Turbidity Maximum in an Estuary
In the present study, a numerical model is used to investigate the transport of sediments in a stratified estuary. The model includes sediment resuspension and deposition as well as three-dimensional,...

Numerical Simulations of the CCS under the Joint Effects of Coastal Geometry and Surface Forcing
Using the S-Coordinate Rutgers University Model (SCRUM) of Song and Haidvogel(1993), a coupled coastal (86 m depth) and deep ocean (4600 m depth) California Coastal region has been investigated...

Observations Related to the Use of the Sigma Coordinate Transformation for Estuarine and Coastal Modeling Studies
One of the common techniques used in application of time-dependent, three-dimensional models addressing estuarine and coastal environmental problems is the sigma coordinate transformation....

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...

The Time Dependent Ray Method for Calculation of Wave Transformation on Water of Varying Depth and Current
This focuses on an aspect of the numerical calculation of wave refraction using the ray tracing or the semi-Lagrangian approach. the conventional ray method for steady state depth and...

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....

Dynamic Loading of Airfield Pavements Caused by Aircraft Operations on Rough Runways
This paper presents results for dynamic pavement loading of various aircraft under takeoff and taxing scenarios. The data were obtained from computer simulation and applied to the Corps...

A Decision Support System for Reassessing the Operation of the Chungju Reservoir System
The Chungju Reservoir is a component of the Han River System in Korea. Chungju Reservoir consists of a main reservoir and a downstream smaller reservoir that serves as an after bay. It...

A Decision Support System for Multi-Purpose Reservoir Operations
A generalized decision support system (DSS) is presented for developing optimal operation policies for multi-purpose reservoirs. The model is designed for single reservoirs, although is...

Evaluating the Steady State Stochastic Dynamic Programming Model for the High Aswan Dam
The paper describes the results of a study to critically evaluate and test the Steady State Stochastic Dynamic Programming model (SSDP). Whenever a reservoir computer model is developed,...

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...

Concurrent E-I Algorithm in Structural Dynamics
A concurrent explicit-implicit algorithm for time integration of the differential equations arising from a finite element discretization is described. The first step of the method consists...

Computer Applications in Structural Analysis and Design
The computer programs have been increasingly used in structural analysis and design to improve productivity. The computer applications in areas of automatic member and foundation design...

Strategic Ship Routing Impacts of Temporal Coverage with Real-time Satellite Altimeter-Based Current Information
We investigate strategic ship routing impacts of temporal coverage with real-time satellite altimeter-based current information. We sample underlying daily `true' current patterns along...

Impulse Effect on Redundancy of a Tied-Arch Bridge
This paper studies the redundancy of a tied-arch bridge using a 3-dimensional finite element computer model. By using static incremental loading simulation, a tied-arch bridge designed...

Discrete Modeling of Soil-Structure Interaction Under Dynamic Loading
A proposal of discrete modeling useful to describe behavior of structures burried in the ground under air explosion is presented. In the modeling emphasis is laid on determining the space...

Developing an Object Based Planning System for Precast Concrete Building Structures
This paper presents the organization of an object based planning system for determining the preliminary costs, schedules and resources for precast concrete building structures. First,...

Computer-Assisted Instruction in Civil Engineering
Computer-assisted instruction (CAI) software offers several advantages over traditional classroom instruction which makes it a useful addition to any curriculum, and the area is rapidly...

A Real-Time Graphical Interface to a Two-Dimensional Groundwater Flow and Mass Transport Model
