Design and Construction of an Optimum Wave Flume

This paper describes the design, construction, and testing of a small wave flume and associated equipment. the wave flume is equipped with a flap-type wave generator, capable of producing both regular and irregular waves. flap paddle is used to examine deep water and floating structures. instrumentation includes three capacitive wave gauges. the wave-maker is controlled by a desktop computer, which also provides data-logging capability. in order to design a wave absorber of restricted length, all the different mechanisms able to dissipate wave energy studied. finally from the survey of the wave absorbers used in different laboratories, a gravel beach designed for absorbing the wavescoming from wave maker. by sealing leaks around paddle the error of measuring height-to-stroke ratios versus relative depth is decreased by 3%. the main advantage of this system over the previous ones is reduction of the amount of effort in the set up with optimum deflection and low level cost utility
