Numerical Simulation of Stratified Flows
The two-dimensional width-averaged equations for flow in estuaries or resevoirs are derived, and the basic assumptions are stated. The heat and salt conservation equations are coupled...

Two-Dimensional Flow Visualization Using the Vortex Computer Code
A computer code has been developed to provide visualization of flow fields with regard to many hydraulic engineering design and analysis problems. The finite-difference computer code VORTEX...

Tidal Modelling on IBM Microcomputers
The finite element code, QUIET, for the simulation of two-dimensional shallow water flow has been adapted from its mainframe form for use on the IBM PC, PC/XT, or AT. The model uses of...

General Continuum Models for Discrete Structures
New knowledge is presented about the structural behavior of a variety of large repetitive lattice configurations of the type appropriate for utilization in cosmic space. Focus is placed...

Damage Detection in Periodic Structures
Nondestructive damage detection in periodic structures using continuum analogues of the discrete structure is studied. Algebraic equations relating changes in eigenfrequencies to the fractional...

Effect of Steel Fibers on the Cracking Behavior of Reinforced Concrete Continuous Beams
A research program was conducted with the aim of studying the cracking behavior of reinforced concrete continuous beams, as it is affected by using different combinations of main steel...

Residual Stresses in Piles and the Wave Equation
A data base of 18 vertical load tests on driven piles in sand is presented. On average the residual point load was 56% of the measured point load and the residual friction load 19% of...

Boundary Element Analysis of Flow in Heterogenous Porous Media
The boundary integral equation method (BIEM) is an efficient numerical method which has been applied to a wide variety of engineering problems governed by a partial differential equation...

Higher-Order Methods for Transient Free-Surface Flows
One-dimensional transient free-surface flows in open channels are described by a set of quasi-linear hyperbolic partial differential equations, called the Saint-Venant equations. Numerical...
