HYDRO 2006 Project Team
The HSB HYDRO 2006 project team is currently busy organising a mass-(e-)mailing to the hydrographic and associated communities. As already announced, the event will take place in November 2006 in Antwerp. The project team consists of a steering committee chaired by Wim v Wieren (NL) and Luc Boehme (BE) and members Peter Boon, Niels Kinne-ging and Rita Peys (Technological Institute/secretariat), a scientific committee headed by Niels Kinneging and a sponsorship committee headed by Rob Berlijn. The organisation is supported by a committee of recommendation manned by the distinguished gentlemen Prof. Jac Spaans (HSB/IAIN), Capt. Floor de Haan (Chief Hydrographer R.Nl.Navy), Cdr. Paul Hornsby (President IFHS), Dr Frank Mostaert (Hydraulic and Hydrological Research Institute, Belgium) and Prof. Dr Jean-Pierre Henriet (Renard Centre of Marine Geology). The organisation has it’s own website at www. hydro06.com where all relevant information can be found.

Hydrographic Survey for Riverbed Erosion

U.S. Geological Survey were out on the Missouri River at Williston, North Dakota, USA, performing a hydrographic survey to monitor the state of riverbed erosion. They were using a multibeam echo sounder which transmits sound energy and analyzes the return signal (echo) that has bounced off the riverbed or other objects. Multibeam sonars emit sound waves from directly beneath a ship's hull to produce fan-shaped coverage of the riverbed.

Gage height at the Williston gage was approximately 27.65 feet when this video was taken. Additional information about the USGS streamgage at Williston is available at http://waterdata.usgs.gov/nd/nwis?program=nwisman&site_no=06330000
