Design and Calibration of a 200-Foot Model Irrigation Border with a Computer Controlled Infiltrating Bed
A physical model of an irrigation border was constructed using a 200 ft long by 2. 5 ft wide tilting flume with a 3. 5 inch deep infiltrating gravel bed. The border was partitioned into...
IIHR's Data Acquisition Systems and Their Applications
The Iowa Institute of Hydraulic Research (IIHR) has recently experienced rapid growth in number of experimental studies, in number of buildings housing these models, and in the diversity...
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....
Centrifugal Abrasion-Resistant Pumps in Intermediate Length Pipeline Systems
The success of long-distance slurry pipelines is in many cases dependent on careful preparation of the solids prior to transport. Positive displacement pumps are employed. However, for...
Series Finished Water Pumping Facilities
The paper discusses studies and design of series finished water pumping facilities for the Potomac River Water Treatment Facilities. Detailed hydraulic studies were conducted which concluded...
Cazenovia Creek Model Data Acquisition System
The purpose of the model is to reproduce river ice breakup phenomena for optimizing the design of an ice control structure. The performance of the ice control structure during a simulated...
Data Acquisition and Control for Hydraulic Models
The Waterways Experiment Station is expanding the use of computer controlled data acquisition and control equipment on a variety of hydraulic models. These systems are presently being...
What Every Hydraulic Engineer Should Know About Technical Information
This paper traces the development of indexing and abstracting of scientific literature and discusses present-day concepts of current awareness, online literature searching and numeric...
A Unique Communication System for Aerial Ropeways
The basic principles of operation of a Double Reversible Aerial Tramway are introduced. A brief note is given explaining a safety circuit or survey current used on the haul rope, since...
Control of the Design Process
Gilbert/Commonwealth, Inc. (G/C) was the architect-engineer for the original design of the Florida Power Corporation (FPC) Crystal River Nuclear Plant, Unit 3 (CR3) and has been involved...
Rockfill Compression Tests and Other Aspects of the Design of Miel I Dam
The Miel I Dam, a high concrete face rockfill dam, is one of the main structures designed for the Miel I Hydroelectric Project in Colombia. Selection of dam type was based on technical...
Microcomputers in Urban Drainage Design
Microcomputers offer an inexpensive method for increasing the efficiency and effectiveness of drainage design personnel. This paper discusses some of the benefits and uses of microcomputers...
Safety as a Prime Consideration
Designs in the 1980's have a multitude of parameters from environmental, noise, aesthetics, planners, community groups, political influence and last but not least, legal/liability...
Freezing and Thawing of Soil-Water Systems
This book presents a state-of-the-practice review on freezing and thawing of soil-water systems through ten interrelated papers on this subject. The papers review the following topics:...
Stormwater Detention Outlet Control Structures
The Hydraulics Division's Task Committee for the Design of Stormwater Detention Outlet Control Structures was formed to review and report on the state-of-the-art of stormwater...
Watertightness and Seepage Control in Roller Compacted Concrete Dams
An unjointed mass of roller compacted concrete (RCC) can easily be proportioned and compacted so that it is essentially impermeable and 'watertight. ' Permeability tests of various field-placed...
Emerging Computer Techniques in Stormwater and Flood Management
These proceedings identify and assemble information on recent applications of mini- and microcomputer technology to problems in urban stormwater and flood management. Instrumentation and...
New Plant Treats River and Well Water
A new 16 mgd water softening plant at Elgin, Ill. is designed to treat raw water either from the Fox River or deep wells, or in any combination. Flexibility of the chemical feed systems...
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...
