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...

Optimal Real-Time Operation of a Cascade of Hydropower Plants in Central West China
The Longxihe River hydropower system consists of four hydropower plants in series. The four reservoirs are used for flood control and power generation. Among the four reservoirs, only...

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...

Sensitivity of Model Choice in Reservoir Design
The Box-Jenkins method of model construction and tests of model adequacy and fit are applied to a reservoir design problem. The sensitivity of the stochastic models used to generate synthetic...

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...

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 Advances in Engineering Mechanics and Their Impact on Civil Engineering Practice
The emphasis of these proceedings is on contributions and advances in the areas of solid and fluid mechanics that advance civil engineering practice. The main topic considered are, computers...

Measurement of Ice Forces on Structures
Methodologies and techniques are discussed for measuring ice forces on fixed structures situated in rivers and lakes. The usual method of measuring ice forces is to place a load frame...

Urban Hydrology and Catchment Research in the United Kingdom - Progress Since 1979
The Wallingford Procedure for the design and analysis of urban drainage systems was released in late 1981 for use by drainage engineers in the United Kingdom. This was the most significant...

Journal of Hydraulic Engineering
The Journal of Hydraulic Engineering accepts original contributions that describe the analysis and solutions of problems in hydraulic engineering. Technical Notes may present a problem, without solution,...

Classic Papers in Hydraulics
Fourteen papers representing basic contributions which made possible rapid advances in analytical techniques in hydraulic engineering are presented. The papers reflect state-of-the-art-...

A Guide for the Field Testing of Bridges
The history and present use of bridge testing are reviewed. The benefits of bridge testing include safety and reliability, the money saved by not constructing a new bridge, the improvement...

How about Reverse Filters
Reverse or inverted filters allow water to drain freely without carrying away suspended solids. Their pore size must be properly related to the fines being protected. Terzaghi's...
