Explicit Finite Element Model for Long Water Waves
An explicit finite element model for free-surface flow is presented. The model is capable of simulating long waves of various orders of approximation in one and two space dimensions. The...
Measurement of Hydraulic Conductivity Variation
For a confined, sandy aquifer, the dependence of the horizontal hydraulic conductivity on the vertical coordinate has been measured using single-well tracer injection/recovery experiments....
Analytic Solution for Seepage from Saturated Soil Behind a Braced Wall
The locations of streamlines and equipotentials for two-dimensional flow in the vertical plane normal to a vertical retaining wall can be determined by various methods. Recent extension...
Analysis of Resonance in Pressurized Piping Systems Via a Microcomputer
In this paper a digital simulation technique for the analysis of resonance is presented that is appropriate for microcomputer applications. The model utilizes the transfer matrix method...
SWRRB.80: A Basin Scale Model for Microcomputers
The SWRRB (Simulator for Water Resources on Rural Basins) model was developed by the USDA Agricultural Research Service to simulate the daily stream flow, and sediment loads from agricultural...
Littoral Environment Observation Program
This paper presents a method for determining the longitudinal, transverse, and vertical dispersivities of a thick aquifer for a free convection tracer test using only measurements from...
Role of Small Computers in Two-Dimensional Flow Modeling
This paper describes the computational aspects and computer usage history of numerical simulations of horizontal, free surface, steady or unsteady two-dimensional flow fields. The focus...
Hydropower's Newest Generation
Higher energy prices and strong incentives from the federal government have caused hydropower developers to consider sites that just a few years ago were scoffed at as mere trickles. Intense...
Time-Dependent Damage and Creep of Brittle Rock
In this paper, some results of a combined analytical-experimental study of the relationship between subcritical microcrack growth due to stress corrosion and the time-dependent deformation...
Constitutive Theories for Solids with Defective Microstructure
The nonlinear mechanical response of solids is a macroscopic manifestation of the irreversible changes in its microstructure. The most common modes of the irreversible microstructural...
Computer Applications in Water Resources
The use of computers in all engineering disciplines has, in the past decade, increased to the point where virtually all engineers now use these powerful tools. This is especially true...
Libby Rereg's Combined Spillway and Powerhouse
The existing powerhouse at Libby Dam, located near Libby, Montana has four generating units for a total of 420 MW. Provisions have been made which will allow doubling the plant rating...
Effects of Streambed Processes on Interaction Between Surface and Groundwater
In open channel systems, the phenomena commonly referred to as 'clogging' is caused by settling of sediment and straining of suspended material as water moves...
Streamflow Losses in the Santa Cruz River, Arizona
The discharge and volume of flow in a peak decrease as the peak moves through an 89-mile (143 km) reach of the Santa Cruz River. An average of three peaks per year flow the length of the...
A Freeway Simulation Program for Microcomputers
An interactive, menu driven macroscopic freeway simulation program with graphic capabilities is presented in this paper. In addition to the employment of personal computers the program...
TRANSYT 7F Applications on a Microcomputer
This paper describes the results of work undertaken by Michigan State University Civil Engineering graduate students as part of two separate class projects. Significant support was provided...
Rating Pavements by Computer
Pavement rating is a necessary and labor-intensive job and one with a high turnover rate of personnel. Also, rating scores are often inconsistent from day to day, or between different...
Pipeline Hydraulic Transient and Leak Detection Analysis
Liquid and gas pipelines cannot be properly designed with consideration of steady flow analysis techniques alone due to the possibility of pipeline failure resulting from uncontrolled...
Advances in CAD for Structural Engineers
In the 1980's Computer-Aided Design (CAD) will offer the structural engineer an opportunity to improve his work. Decreases in the cost of equipment and improvements in computer-aided...
Turbidity Generated by a Model Cutterhead Dredge
The study of turbidity generation indicates that, in general, turbidity increases with an increase in the cutter speed and an increase in the cutter swing velocity. A silt curtain deployed...
