A system includes a conduit, a sensor system and a controller. The conduit may be associated with a structure, having a portion thereof disposed on a surface, and being disposed in a direction normal to the surface. The controller is in communication with the sensor component. When the sensor system is operable to detect when sediment on the surface and surrounding the structure is removed from an area around the structure, an initial length, l.sub.i, of the conduit is disposed below the surface of the sediment on the surface and surrounding the structure at an initial time. When the sensor system is operable to detect when sediment is deposited around the structure, the initial length, l.sub.i, of the conduit is disposed above the surface at the initial time.
