Abstract: The studies on physical models pertaining to the phenomena such as bed-load transport, breakwater stability, local scour around submerged structures etc. require detailed bed level mapping. The paper describes a bed surface profiler system, developed at the Central Water and Power Research Station (CWPRS), Pune, India. The profiling system consists of a bed sensing probe driven vertically, two carriages to move in two orthogonal directions and a Personal Computer for control of movement of these. The probe is provided with an optical switch for sensing the bed. The vertical movement of it produces a signal for computer for positioning it to the next cartesian co-ordinate by movement of carriages. The operations of probe movement for bed level sensing, locating the probe to the next point of interest, bed profile data collection, on-line graphical display and storage are carried out automatically by the Personal Computer running under the control of a software package developed at CWPRS. The profiling system as developed was used extensively for profiling the breakwater sections in a wave flume at CWPRS and has worked successfully. Some test results are presented.
