Proportioning Reinforcement for Buried Concrete Pipe
The proportioning of reinforcement between inner and outer cages that is specified in ASTM Standard Specification C76 for concrete pipe in sewer and culvert applications is examined in...
Predicting Overland Flow and Infiltration
The kinematic overland flow and the Green-Ampt infiltration equations are coupled and rewritten in terms of several nondimensional parameters. Constant values of these parameters imply...
Aggregation and Consolidation of Phosphatic Clays
The consolidation behavior of aggregated phosphatic clays has been investigated using a bench scale centrifuge. It was determined that aggregation of the clays with phosphogypsum, a waste...
South Branch Rockaway Flood Water Study
The paper reports on a study to analyze in detail various methods of storm water management. The technical studies were carried out in an actual watershed setting to arrive at a recommended...
Application of Interactive Computer Simulation to Water Resources Problems in Civil Engineering Education
The major educational advantage of interactive simulation is expedient demonstration of system management and control procedures and interrelationships among system variables. An 8 year...
Entrainment of Interstitial Water by Overland Flow
The paper reports on a study to investigate the entrainment of interstitial soil water by overland flow. A diffusion model was developed to describe the subsurface concentration and the...
Turbidity Control Measures Associated with Reclamation of an Abandoned Phosphatic Waste Clay Pond
Area 3A in the Tenoroc State Reserve near Lakeland, Florida is an inactive and abandoned phosphatic waste clay area. The disposal area has been inactive for several years and the clays...
Advances in Selective Withdrawal
The authors present the results of recent selective withdrawal research in the form of a general mathematical description of this stratified flow phenomenon. A new description for boundary...
Ground-Water Drainage to Surface Mines Refined
Changes in seepage flux and hydraulic head (ground-water level) resulting from ground-water drainage into the first and subsequent cuts of a surface coal mine can be estimated by a technique...
A Numerical Model of Water Movement Through Clay Liners
Regulations controlling landfill design typically specify design details such as a minimum liner thickness, maximum permeability of required gradation curves for the clay liner material....
Input/Output Schemes for Microconverted Engineering Application Programs
When converting mainframe programs for microcomputer use, different input/output schemes are implemented depending on the type and volume of program data and ultimate use of the program....
Present Status of Research in Debris Flow Modeling
A viable rheological model should consist of both a time-independent part and a time-dependent part. A generalized viscoplastic fluid model that has both parts as well as two major rheological...
Modeling Aquifer Sensitivity and Leachate Controls
This paper investigates the transport of waste leachate from a leaky containment facility using the computer model of Two-Dimensional Solute Transport and Dispersion in Ground Water developed...
Yakima Remote Control System: Supervisory Control and Data Acquisition
The Yakima Remote Control System is a computerized supervisory control and data acquisition (SCADA) system developed for the operation of the Bureau of Reclamation's Yakima Project in...
Response of Floating Structures in a Directional Sea
A finite element numerical model is presented to predict the behavior of long floating structures in a multi-directional sea. A follow up numerical model analyzes an important but mostly...
Lake Water Level and Sediment Management?Case Studies in Illinois
Estimation of the sedimentation in the lake is based on the soil erosion rates in the watershed, the sediment transport in the stream system, and lake trap efficiency. Erosion rates are...
Vortices at Vertical Intakes
This paper presents the results of an experimental investigation designed to predict the formation of weak, free-surface vortices at vertical intakes with a headrace channel. A weak vortex...
Exfiltration Trench Design as Part of a Stormwater Management Plan
The paper discusses a program structured to assist the design consultant or the agency reviewer by means of a menu driven format. A flood routing microcomputer program developed by the...
Overtopping of Small Dams?An Alternative for Dam Safety
A research effort was initiated in 1983 by the Bureau of Reclamation to gain insight in the development of cost-effective modifications to small embankment dams which would enable them...
Embankment Overtopping
Embankment overtopping and dam safety are major concerns of civil engineering and the general public. Very little is known about overtopping events and much less has been published or...
