Tributary Loading with a Terrain Following Coordinate System
The modeling of physical processes that occur in a tributary between the farthest downstream gage and the lake interface can help to improve the predictive capabilities of Great Lakes...

An Energy Based Model for Coastal Bays and Lakes
The North American Great Lakes have numerous tributary bays and small lakes along their coastline that open directly to the Great Lakes through natural or engineered channels. As a consequence...

Conservation Properties of the Mild Slope and Boussinesq Equations
Common water wave evolution equations, such as the mild slope equation, parabolic approximations and Boussinesq equations, are approximate statements of conservation laws. A feasible measure...

Nonlinear Decomposition of a 2-D Wave Field

A second-generation numerical wave model, WINDWAVE, has been developed for wave prediction in coastal regions. The modal is based on the numerical integration of the energy balance equation...

Nonlinear Effects on Wave Envelope and Phase
The representation of second-order random waves is examined in terms of the effect of second-order nonlinearities on the wave envelope and phase. Theoretical expressions describing the...

Spectral Boussinesq Modelling of Breaking Waves
Random waves passing over a shallow bar are considered, in particular the amplification of bound harmonics in shoaling water, their subsequent release in deepening water, and the role...

ASA.WAVES: An Interactive PC-based Wave Forecasting Tool
An interactive PC-based system for wave refraction-diffraction in coastal regions has been developed, based on a Mild-slope equation finite element wave model. The system includes an embedded...

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...

Empirical Performance Comparison for Symbolic and Subsymbolic Learning Systems
The paper gives a description of a comparative study of two learning systems based on symbolic and subsymbolic learning. The two systems' performance was analyzed using the overall empirical...

Estimating Sediment Relative Density Using an Impact Core Sampler and Wave Equation-based Pile Analysis
This paper presents a case history in which soil sample drive resistance was modeled with a wave equation-based pile analysis computer program to estimate in situ sediment relative densities...

Compressibility for Sand Under One-Dimensional Loading Condition
Empirical equations for one dimensional compression of sand do not include parameters characterizing properties of sand grains (e.g. moduli, size and shape of sand grains, and friction...

Poorer Is Riskier: Opportunity for Change
With regard to water resources, it is appropriate to build upon two interacting themes of the late Aaron Wildavsky (1988). The first of Wildavsky's themes is the idea of resiliency. The...

Computing Two Dimensional Flood Propagation with a High Resolution Extension of McCormack's Method
McCormack's method, as applied for solving the bidimensional de Saint Venant equations is enhanced with the aid of the theory of Total Variation Diminishing (TVD) schemes in order to obtain...

Modelling of Flood Wave Propagation Over Flat Dry Areas of Complex Topography in Presence of Different Infrastructures
After a description of the general equations which govern the propagation of a 2D flood wave (shallow water equations), a review of the scientific publications on the integration of their...

Formation and Propagation of Steep Waves: An Investigative Experimental Interpretation
From the end of the last century, many Authors have studied experimentally the formation and the propagation of steep waves on dry flume bottom. Up to the present time, however, some aspects...
