Responsible Governmental Structures: Coastal Management in the United States, Great Britain, and Australia
Commentators studying the coastal management strategies adopted by various countries have frequently criticized the lack of centralized national authorities aimed specifically at coastal...
A Classification of the Coastal Dunes of Louisiana
The aeolian deposits of the barrier coastlines of Louisiana to the west of the active delta of the Mississippi have been studied intensively for almost 20 years. The dunes, dune terraces...
Preliminary Study on Impacts of Sea Level Rise and Response Strategies in Japan

Well Response in a Leaky Aquifer and Computational Interpretation of Pumping Tests
An analytic solution is derived describing flow in a horizontal confined leaky aquifer of infinite extent around a fully penetrating well of negligible storage capacity. The differences...
Nonlinear Hydrodynamic Pressures on Dam Faces with Arbitrary Reservoir Shapes
A finite-difference method was used to calculate the nonlinear hydrodynamic pressures acting on the rigid dam faces during earthquakes. The geometry of the reservoir is in a realistic...
Nonlinear Flow in Embankments
For a large number of water resources projects, the Dupuit-Forchheimer (D-F) assumption is considered a viable design criterion and, consequently, Darcy law is used to determine the locus...
Roll Waves in Mud Flow
Permanent roll waves on a shallow layer of fluid mud which is modeled as a power-law fluid is studied. Based on long-wave approximation, momentum integral method is applied to derive the...
An Optimization Approach to River Adjustments
The adjustment of alluvial channels is presented here as a non-linear optimization problem in which the ideal channel will tend to adopt an optimum configuration subject to the imposed...
A Finite-Difference Model for 3-D Flow in Bays and Estuaries
This paper describes a semi-implicit finite-difference model for the numerical solution of three-dimensional flow in bays and estuaries. The model treats the gravity wave and vertical...
Unified Constitutive Model for Airport Pavements
A unified constitutive model that allows for significant behavioral characteristics of materials and interfaces in airport pavement is implemented in a nonlinear finite element procedure....
Specific Applications
In recent years, practicing engineers have begun to use nonlinear finite element methods to design and evaluate increasingly complex concrete structures. This chapter presents several...
Behavior of Suction Piles in Sand
In the marine environment, use of suction pressure for the installation of sealed top piles (suction piles) is a promising alternative to driven pile foundations, particularly in deep...
Pultruded Composites: Materials for the 21st Century
The main objective of this paper is to introduce pultruded composites to the civil engineers and to create the awareness of its important applications. A description of the pultrusion...
