ABSTRACT
Details for the instrumentation and experimental results from measurements of the application of suction from the bed in open channel have been presented in previous articles [3,4,5]. We mention for completeness of the present study that measurements were conducted with LDA (tracker) and hot film methods, the suction rate is based on discharge ratio (Qs/Qtot, Qs = suction discharge, Qtot = total discharge), the length of suction region L = 0.035 m, and the Re number based on upstream velocity Um and flow depth was Re = Umh/ = 59,000.
