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...
Flow Computation and Energy Performance Analysis for Hydropower Components
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...
Dynamic Interaction of Bridge and Moving Loading
Coastal Processes on the Wai-San-Ding Barrier of Taiwan STrait, R.O.C.
The coastal line processes on the Wan-San-Ding Barrier is discussed in this paper since 1900. The wave energy along this coast is computed from the measured wave by considering the refraction...
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....
Oil Under Ice: Buoyancy Viscous Spreading
Entropy-Based Velocity Distribution Model in Study of Distribution of Suspended-Sediment Concentration
Wave-Current Interaction with a Large Structure
The effects of a current on the diffraction of regular waves around a three-dimensional body are examined by a time-domain method. The Froude number is assumed to be small so that the...
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...
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...
