Description: Das Projekt "Entwicklung eines Systems zur akustischen Profilbildung von Schwebstoffen und dessen Anwendung in den Bereichen Technik und geophysikalische Hydrodynamik" wird vom Umweltbundesamt gefördert und von Ecole Polytechnique Federale de Lausanne, Institut d'Hydraulique et d'Energie durchgeführt. An acoustic Doppler velocity profiler (ADVP) both in monostatic and bistatic configuration measures accurately profiles of mean velocity u(y) and v(y) and of turbulence u'(y) and v'(y)over the depth y. We now extend this instrument towards simultaneous measurement of suspended sediment (particles) concentration profiles c(y) in turbulent flow to obtain a high resolution Acoustic Sediment Transport Profiler (ASTP) which will measure the instantaneous profile of sediment transport: qs(y) = c(y) u(y) = y.The ASTP will allow the study of sediment transport mechanisms with a temporal and spatial resolution that has not existed before. The practical application of this new ASTP is found in the studies of river sediment transport, pollution transport and spreading, sediment deposition in reservoirs, turbidity currents in reservoirs and reservoir purging.
