Boundary Forcing and a Dual-Mode Calculation Scheme for Coastal Tidal Models Using Step-Wise Bathymetry
Tidal energetics are persistent and important factors in almost all coastal regions. As such, it is important to employ techniques that can consistently reproduce observed tidal variations....

Development and Application of a Three-Dimensional Boundary-Fitted Circulation Model in Providence River

Modeling the Seasonal Circulation in Massachusetts Bay
An 18 month simulation of circulation was conducted in Massachusetts Bay, a roughly 35 m deep, 100×50 km embayment on the northeastern shelf of the United States. Using a variant of the...

Kinematics of Wave Overtopping on Marine Structure
Kinematics of transient wave overtopping on coastal breakwaters has been studied both experimentally and numerically. For the laboratory experiments, solitary waves with moderate wave...

Implementation of Elastic Layered Theory for Design of Unbonded Overlays
The U.S. Army and Air Force have implemented the elastic layered theory for design of unbonded overlays for rigid airfield pavements. The procedure allows for design of unbonded overlays...

Hydrodiplomacy on Forester Creek
The goal of this paper is to share information regarding political battles confronting the engineer with regards to drainage issues and concerns. Very often drainage boundaries do not...

Radionuclides Migration in Fractured Porous Rock: Analytical Solutions for Various Boundary Conditions

Numerical Studies of Radionuclide Migration in Layered Porous Media

Demand/Supply Relationship in Transportation Network Design Problems: A Genetic Algorithm Approach
The cumulative genetic algorithm (CGA) has its significant advantages over the heuristic algorithms in dealing with transportation network design problems. Using CGA, the entire solution...

Fracture Mechanics Analysis of Welded Joints Using Boundary/Finite Element Alternating Methods

Extensions of Finite Element Dental Stress Analysis
Some two dimensional models for stress analysis of dental crowns are examined and compared in relation to boundary conditions and some other issues in finite element analysis. The current...

Deformations in Sand Layer During Pile Driving
This paper presents measurements of settlement and lateral soil movements in a medium dense to dense sand layer due to densification during driving of precast concrete piles. At one end...

The Influence of Engineering Judgement in the Settlement Analysis of a Test Fill Near Châlon-sur-Saône, France
This paper describes the settlement study for a test fill near Chalon-sur-Saone (France). The soil profile at the site comprised a silty clay layer 4.2 m thick. The elevation of the ground...

Displacement of Batter Piles in Layered Soil
The displacements of flexible vertical and batter model piles under eccentric and inclined loads in layered soil of clay overlying sand is studied. Horizontal and vertical displacements...

Effect of Roughness and Thickness of Biofilms on External Mass Transfer Resistance
The effect of roughness and thickness of biofilms on the dissolved oxygen (DO) concentration boundary layer thickness (DO CBLT) and the external mass transfer process in a biofilm system...

LDV System for Towing Tank Applications
The design, construction, testing, and operation of a two-dimensional LDV system for use in a towing tank is described. The primary design considerations were underwater application, minimal...

Observations on the Growth of an Internal Boundary Layer with a Lidar Technique
The distribution of atmospheric water vapor across a step change in surface humidity (dry-wet) was observed by a Lidar measurement technique under neutral atmospheric stability condition....

Reconstruction of Concentration Boundary Condition for Unsteady Pesticide Transport Modeling
A one-dimensional unsteady contaminant transport model which used an unsteady hydraulic field was used to model pesticides (metolachlor, metribuzin) in the Iowa River/Coralville Reservoir....

Modeling 3-D Ground Water Mounding
Groundwater mounding is caused by localized recharge to the saturated zone in an unconfined aquifer. Estimation of groundwater mounding shape and height is important to provide an estimate...

Influence of a Sand Layer on Headcut Advance
The presence of an erodible material layer in the soil profile has been observed to influence headcut movement in earth emergency spillways. Large-scale flume tests were conducted to examine...
