Implementation of a Micro-CADD System
Computer-aided-design-and-drafting (CADD) systems utilize computer technology to aid the engineer in his work. CADD systems are designed to process graphics with speed and accuracy to...
Water Distribution Design with Multiple Demands
An iterative procedure for the layout and design of new looped water distribution systems is pesented. The procedure is also applicable to the expansion of existing systems. The approach...
Practical Optimization of Looped Water Systems
This paper describes one tool that might be part of a package to assist a design engineer in sizing pipes, determining ideal locations for booster pumps and their heads, determining heads...
OPNET: A Nonlinear Design Algorithm for Hydraulic Networks
The author has developed a general computer program OPNET to be used in the optimal design of hydraulic networks. The computer program can be used to optimize three basic variables; tank...
Integrated Operation of the Ottawa River System
Several years ago, an integrated operating process was developed in response to specific problems on the Ottawa River. The operating process involves several public-sector organizations...
Computerized Design and Selection of Pumping Systems
Three computer models have been applied in the evaluation, design and selection of a high-lift pump station upgrading program developed for the City of Poughkeepsie, New York. The three...
Integrated Design Methodology for Urban Stormwater Detention Facilities
The objective of this paper is to present the core of a design methodology that avoids the pitfalls of the design storm concept by using a microcomputer algorithm to estimate the long-term...
Computer Aided Design Using CORPS
The Hydraulic Analysis Division, Hydraulics Laboratory, US Army Engineer Waterways Experiment Station (WES) has the responsibility for developing and disseminating hydraulic guidance for...
Conceptual Framework for Regression Modeling of Ground-Water Flow
The author examines the uses of ground-water flow models and which classes of use require treatment of stochastic components. He then compares traditional and stochastic procedures for...
Numerical Modeling of Groundwater-Lake Systems
Groundwater inflows can have important effects on the chemistry and biology of a lake ecosystem. For example, studies of lakes in Northern Wisconsin documented localization of ferromanganese...
Risk-Cost Analysis and Spillway Design
The NRC's recent report on dam safety proposes risk cost analysis to help select among alternative spillway modifications for existing dams. This paper examines the sensitivity...
Hydraulic Profile Computation Using CADD
The data preparation can also be performed by directly recording onto a computer tape the aerial survey cross section ground points and the field survey work. A computer program can then...
Fluidization of Biomas Covered Sand Particles
The expansion behavior of the fluidized bed reactor support medium is important in its design and analysis. Steady state and dynamic behavior of fluidized bed expansion were compared with...
Understanding Secondary Clarifier Behavior
The author has developed a graphic procedure for analyzing the hydraulic behavior of settling tanks. Data have been used in numerous cases to devise low cost in-tank and external improvements...
Cultivation of Christmas Trees Using Reclaimed Municipal Wastewater
This investigation was initiated to identify benefits and limitations associated with application of reclaimed domestic wastewater to a crop of improved Virginia pine christmas trees....
Seepage and Leakage from Dams and Impoundments
All major dams and impoundments are usually analyzed to determine the magnitude and location of seepage that can occur under, around or through the structure. More often than not, seepage...
Issues in Dam Grouting
Although perhaps the largest number of individual grouting projects do not involve dams, by far the largest volume of grout used is for grouting of new or existing dams. This volume presents...
Irrigation Canal Seepage and its Measurement
Reduction in seepage is one of the primary reasons used to justify investment in canal lining. Such justification depends greatly upon estimates of seepage through surface and subsurface...
Effect of Surge Cycle Ratio and Cycle Time on Infiltration
A recirculating furrow infiltrometer was used to simulate surge flow irrigation for various cycle times and cycle ratios. The data collected was used to evaluate two empirical surge flow...
Incorporating Crop Water Use in Drainage Design in Arid Areas
A method of drainage design for use in arid areas was developed by combining procedures proposed by D. B. McWhorter along with plant uptake functions developed by D. W. Grimes and D. W....
