Friction Factors in Coastal Flooding
As the world's coastal zones are being developed and the coastal population increases, coastal flooding, or rather the prediction of its extent and frequency of occurrence, becomes a more...
Uptake of Contaminants by Overland Flow
A mathematical model is developed for the uptake of contaminants by overland flow. The model is based on the numerical solution of the Navier-Stokes equations coupled with a two-equation...
Multiquadrics in Engineering Modeling
The theory of multiquadrics (MQ) is advancing rapidly and it is usable today. When appropriate MQ can accurately interpolate for unknown values with less computational cost than Kriging....
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...
Problems with Numerical Modeling of Gravel-Bed Rivers
Inherent to one-dimensional numerical models are the assumptions that hydraulic parameters can be assigned a characteristic average value, and that the flow is gradually varied so that...
Numerical Solution of Transient Closed-Conduit Flow Equations by the Method of Lines Along Characteristics
The method of characteristics has long been considered as a natural technique for solving transient closed-conduit problems. In this paper, by using the concept of the method of lines,...
Kenetic-theory Approach to the Nevado Del Ruiz 1985 Debris Flow
The Nevado del Ruiz 1985 debris flow was the worst disaster of its kind in this century, killing 22,000 people. By making an idealization of the debris flow material and the flow regime,...
Comparisons Between Experimental and Numerical Studies on Laminar Flow with Tracer Transport
In this paper we present an experimental and an accompanying numerical study of two- and three dimensional transient flow and tracer transport in complex flow systems at low Reynolds numbers....
Debris Flow Initiation and Termination in a Gully
A comprehensive simulation model predicting the debris-flow discharge hydrograph, solids concentration in it and the process of variation of the channel due to vertical as well as lateral...
Driven Then Pushed Minicone Tests in a Sand Chamber
For a general knowledge on the Standard Cone Penetrometer test and its uses the reader is referred to the work of Briaud and Miran (1991). For this study (Khalaf and Briaud, 1992) a smaller...
Piles for Marquette University Math Building
This paper presents a comparison of static pile capacity predictions using CPT cone resistance results with results of a test pile program and production pile driving. Pile capacity prediction...
Evaluation and Monitoring of Pile Performance Using Dynamic Measurements in Supporting Offshore Structures
The installation of offshore platforms into deeper waters and new environments is accompanied by an increasing uncertainty in the structure response, foundation design and performance....
Seismic Wave Propagation by Finite Differences on the Connection Machine
Seismic modeling represents a difficult numerical challenge and consumes a significant amount of CPU time on the largest available supercomputers. With the advent of massively-parallel...
The Control of Large Amplitude Liquid Sloshing with Moving Baffles
Numerical simulations of three-dimensional viscous liquid sloshing in rectangular containers were carried out using an improved volume of fluid technique in conjunction with the Navier-Stokes...
Landslide-Generated Waves in Reservoirs
This paper investigates surge waves generated by landslides in reservoirs. The Navier-Stokes equations with complete viscous conditions at the free surface are solved numerically for the...
Multiple Modes of Steady-State Slide-Rock Response
The dynamic response of free standing rigid bodies to base excitation can be quite complex, as evidenced by the five motions or modes to be considered in a two-dimensional analysis: rest,...
Screen Breakwaters
The diffraction of water waves by an offshore breakwater consisting of an infinite row of equally-spaced vertical screens is investigated theoretically. The reflected and transmitted wave...
Computation of Wind Pressures on L-Shaped Buildings
The paper refers to the numerical simulation of turbulent wind conditions around an arbitrarily-shaped building composed of two rectangular blocks. The time-averaged Navier-Stokes equations...
Computation of Flow in Ice-Covered Dune-Bed Channels
A numerical method for solution of the Reynolds-averaged Navier-Stokes equations is developed to study the flow over sand dunes in two-dimensional channels. The method is applied to calculate...
Improved Time-History Analysis for Structural Dynamics Calculations
Methods are developed to reduce the computational effort in time-history analysis of nonlinear structures. The methods permit use of much larger time intervals than are possible in conventional...
