Modeling of a Multifunctional Hydraulic Structure
A 1:12 scale Froude model of a hydraulic control structure in the Rochester Combined Sewer Overflow Abatement Program (RCSOAP) was constructed and tested to optimize the design requirements...
Streamflow Measurement and Analysis for Northwest Rangelands
Watershed hydrologic and sedimentation investigations on the Reynolds Creek Experimental Watershed in southwest Idaho were initiated in 1960. Major objectives of the watershed research...
Increased Reservoir Cost to Meet Instream Flow Needs
Low flow criteria need to be developed for determining the suitability of various low flow regimens for fish and wildlife. For choosing a desirable low flow release, the decision maker...
Controlling River Ice to Alleviate Ice Jam Flooding
Many communities affected by ice jam flooding have accepted the event as unpreventable. Others have approached their problem as one of open channel flow and implemented standard projects...
Salmon River Ice Jams
The ice conditions on the river during the freeze-up period and the simple analytical model used to predict the advance of the ice cover leading edge are documented. Ice cover thicknesses...
Mathematical Modeling of River Ice Process
Computer modeling of flow and ice conditions in a river is an important element in the planning of water resources project in northern regions. River ice processes are closely related...
Reduction of Intake Flow Due to Ice Rubbling and Consolidation
Numerous seawater intakes have been designed for Arctic Coastal Waters. In these areas moving ice often causes rubbling and pile up of broken ice pieces against the shore. If this forms...
Hydraulics of Freeze-up
A classification scheme for freeze-up of a river is proposed based upon the response of indicated stage. A conceptual model is developed to describe the course of the indicated responses....
A Quantitative Assessment of Surface Water Resources for Coal Slurry Pipelines Originating in Southwest Virginia
In view of the high streamflow variability, preliminary quantitative assessment was made of the capacity requirements and low-flow frequency characteristics of offstream reservoirs needed...
Artificially Varied Flow: River System Management
Some of the major water quality problems are heat, color, organic sediment, and total dissolved solids. To dilute these and other pollutants, substantial augmentation of flows for water...
Field Flow Measurement of Hydro-Turbine Efficiency
Performance tests were conducted at Great Northern Paper (GNP) Company's Weldon Hydroelectric Station. The purpose of the tests was to calibrate the Winter-Kennedy taps and...
Research in Hydraulics at California Institute of Technology
Activities are centered in the W. M. Keck Laboratory of Hydraulics and Water Resources. Research projects active at the Laboratory reflect a continuing commitment to traditional areas...
Hydraulic Research--U.S. Geological Survey
Research at the Gulf Coast Hydroscience Center near Bay St. Louis, Mississippi, is being conducted in an indoor laboratory, and an outdoor laboratory. Much of the current indoor lab research...
Modeling Pool and Riffle Sequences in Alluvial Channels
A one-dimensional mathematical model has been developed to predict the hydraulic characteristics of alluvial channels under low flow conditions. For a given steady discharge, channel geometry,...
Kinematic Shock: A Sensitivity Analysis
A series of numerical experiments is performed to determine the flow and channel characteristics that are most conducive to kinematic wave steepening and associated shock phenomena. A...
Plastic and Other Limit State Methods for Design Evaluation
These proceedings consist of seven papers dealing with the topic of the design of complex structures using limit state methods. The emphasis is on the role of plastic or limit load techniques....
Structural Plastics Design Manual
The structural behavior of plastics reflects a number of characteristics different from those of the metal, lumber, and concrete materials familiar to most design engineers. This manual...
Guidelines for Transmission Line Structural Loading
Procedures are provided for the selection of design loads and load factors based on the latest research and state-of-the-art design techniques. This selection has an effort on the reliability...
Electronic Traffic Management
High technology has entered the world of traffic and transportation management with such new optical and electronic devices as transponders, retro-reflective stickers, microprocessors,...
Recent Developments in Pavement Skid Resistance
As pavements wear, they lose some of their skid resistance. This article discusses some of the leading options for restoring a pavement's skid resistance. The possibilities...
