Profiling Sonar Device

The University of Southampton intends to deploy a sonar device on a pier of a bridge (which still needs to be identified as many options are available) to monitor local and general scour of the river bathymetry in proximity of the pier foundations. The experiments intend to investigate the evolution of local scour across a wide range of temporal scales that go from hours to years. 1- The sonar should allow for long-term immersion periods (minimum 6 months, 1 year preferable) and require minimal maintenance. 2- The...
