The Riverboat is the undisputed platform of choice for ADCPs used in hydrologic monitoring, offering unmatched data quality and instrument stability. Riverboats can be equipped with a range of GPS positioning instruments. ADCPs offer detailed velocity and discharge data, however, without a stable deployment platform, the data quality is compromised. Trimaran Riverboats for the Teledyne RDI RiverRay, RiverPro, and StreamPro are standard, with custom boats for other profilers also available. The High-Speed Riverboat can be used with multiple profilers, and its innovative hull design further expands the applicability of ADCPs to hydrology in challenging flow conditions.
