Applications of a Two-Equation Turbulence Model to Geophysical Boundary Layers

On the Diurnally Varying Topographic Flow Over an Isolated Island

Mass Conservation in the RMA2V Code
This paper discusses the RMA2V hydrodynamic code with a particular interest in mass conservation problems. These originate from at least two sources. One of which is the slip flow boundary...

A Two-Dimensional Model for Estimating Leachate Flow in Landfills
A numerical model has been developed to compute the leachate flow from solid waste landfills in an unsteady state condition. The two-dimensional moisture flow equation along with the boundary...

An Overview of the NASA (LeRC)-SwRI Probabilistic Structural Analysis (PSAM) Program

Seismic Large Amplitude Liquid Sloshing—Theory
The sloshing phenomenon in seismically-excited, rectangular, liquid storage tanks is addressed. In particular, a semi-analytical method to study the effects of large amplitude sloshing...

Comparison of Slitted and Non-Slitted R. C. Shear Walls With Boundary Elements Under Horizontal Forces
This paper compares the differences of aseismic behaviours between slitted and non-slitted shear walls under horizontal forces. There are 5 specimens for slitted shear walls and another...

Vectorized Multigrid Solvers for the 2-D Diffusion Equation

Longshore Currents and the Effects of Wind Stress

Proper Use of Effective Flow Boundaries
The determination of the appropriate effective flow boundaries is an important factor in the hydraulic modeling of the flow regime of a stream. It is especially critical in areas with...

Diplomacy and International Environment Issues
This paper examines three current examples of the ongoing diplomatic efforts to deal with selected environmental and water issues that affect our bilateral relationships with Canada and...

The Formation of Meandering and Braided Channels
Flow in alluvial channels implies flow past boundaries that form and deform under the action of the flow. Interaction between the flow and the mobile boundaries produces channel patterns...

A Method to Treat Incident Wave Condition in Shallow Water Equation
A method to consider open boundary condition of the shallow water equation to analyze water surface wave and tide is employed in the finite element anaysis. This can be done by considering...

Flow Modeling in the Toutle River, Washington
In support of flow, suspended load, bed load, and bedform transport measurements, a quasi-three-dimensional river flow model was adapted to a reach extending from 260m upstream to 30m...

Mechanics of Mud Flows in Curved Channels with Uneven Beds
Most natural debris flows move through paths that are curved and that have significant bed topography. Owing to the dependence of the mechanics of wet debris containing substantial amounts...

Two Dimensional Nonequilibrium Transport of Nonuniform Sediment
Mathematical models based on diffusion and/or diffusion convection equations have been widely applied to study sediment transport in suspension. Some of the studies were reported by C.C....

Boundary Element Methods in Structural Analysis
Tutorial and state-of-art aspects of the Boundary Element Method (BEM) are combined with applications in structural analysis in order to provide information about the advantages of this...

Boundary Conditions of Tidal Model at River Mouth
A small grid is required to schematize irregular shape of shoreline in the vicinity of river mouth which limits the modeling area to be small. Tidal records along the boundary show no...
