Real-time Control of Combined Water Quantity & Quality in Open Channels

Fresh water supply and flood protection are two central issues in water management. Society needs more and more fresh water and a safe water system to guarantee a better life. A more severe climate will result in more droughts and extreme storms. As a consequence, salt water intrusion will increase. Therefore, clean and fresh water is becoming...

Design of open-channels and hydraulic structures

Lecture note on open channel hydraulics, hydraulic structures, regulators, weirs, drop structures and stilling basins.

Estimates of Roughness Coefficients for Selected Natural Stream Channels with Vegetated Banks in New York

Water-surface profiles were recorded and Manning's roughness coefficients computed for a range of discharges at 21 sites on unregulated streams in New York State, excluding Long Island. All sites are at or near U.S. Geological Survey streamflowgaging stations at which stage-to-discharge relations are relatively stable and overbank flow is absent...

Some aspects of the design and operation of water management systems

This study deals with the design of water management systems. Attention is focused on that phase in the design process in which variants are developed and evaluated with emphasis on the evaluation. The proposed evaluation procedure combines an economic evaluation with an evaluation of the hydraulic qualities- The economic evaluation implicates...

Dynamic forces on a bed element in open channel flow with a backward facing step

Experiments to measure forces on objects in open channel flow behind a bacward facing step

Turbulence measurements using a small electromagnetic current meter in open channel flows

The use of a small two-component electromagnetic current meter to record turbulent velocities in a laboratory flume is described. The results from these experiments are compared with results obtained previously using different measuring techniques.
