Potentiality of a velocity profiler to investigate sewers: Results of laboratory experiments

In order to propose a new sewer inspection method, a velocity/turbidity profiler (Ubertone, UB Flow F-315) has been tested in a laboratory. A 50 m glass flume has been adapted with several lateral connections (with a range of diameters, angles, intrusions, cracks), supplied by a 1 m3 tank. Placed just below the free surface on a rotating (to...
