Combined Boundary Element and Finite Element Analysis of Composite Slab on Girder Bridges
In this paper, the coupling of boundary element and finite element methods and its application to analyze slab on girder bridges are studied. The boundary element method (BEM) is employed...

The Analysis of Plate-bending Problems with Boundary Elements

Screening Effectiveness of Surface Wave by In-filled Trench with Using Boundary Element Method

Salinity Variations in Two Louisiana Estuaries
Salinity variations, on a variety of time scales, are described for two shallow bar-built estuaries of the Louisiana coast. Tidal, sub-tidal, and seasonal scale variations are important...

Partnerships Strengthen Watershed Management
In reaching across political and institutional boundaries to manage nonpoint source (nps) programs, agencies are recognizing the need for strong communication, coordination and planning....

Tidally-Induced Sediment Transport on the Amazon Prodelta
A study of boundary-layer processes on the Amazon River prodelta region was conducted as part of the Amazon Shelf Sediment Study (AmasSeds). Over a 2-week period during the time of high...

Shoreline Management of Eastern England
This paper gives a perspective on the length of coastline falling within the boundary of the National Rivers Authority, Anglian Region (NRA) in respect of the shoreline management carried...

Anisotropic Effects on Flow from a Recirculation Well
We examined flow in an unconfined aquifer near a recirculation well, which consists of a source and a sink of equal strength, with emphasis on understanding the effects of anisotropy....

An Optimal Parameter Estimation Model for Groundwater Resource Management
An optimal parameter estimation model is developed to identify the locations of wells, to determine pumping magnitude, and to calculate transmissivity coefficients in a confined aquifer...

Flow Resistance Properties of Flexible Linings
Flow resistance for flexible channel linings is a function of the relative roughness of the lining in accordance with boundary-layer principles. As with vegetation, flexible linings have...

Riprap Design at Bridges–Factor of Safety Approach
The factor of safety method offers a physically based methodology for design of riprap that relates the applied shear stress on the channel boundary to the stability of the riprap layer....

An Overview of Methods to Delineate Capture Zones of Pumping Wells
Rainfall over the surface area of an unconfined aquifer, which contributes flow to a pumping well under Dupuit conditions, was estimated. Using a two-dimensional analytical model with...

Wave Boundary Layer Above the Submerged Coastal Slope
A calculation method of parameters of turbulent boundary layer formed by waves is proposed. A calculation of boundary layer on a rough slope with inclination typical for steep Caucasian...

Experimental Testing of Laterally Loaded Large Scale Bridge Abutments
The challenges to a bridge analyst in defining abutment boundary conditions and the current state of the practice are presented. Variables within the abutment system are defined and discussed...

Limitations of Reduced Scale Testing on Parshall Flumes
A model for the boundary layer development in the entrance section of a Parshall flume is developed to account for the effects of fluid viscosity on flume calibration equations. Data for...
