Storm Geomatics Completes Wide Swath Bathymetric River Aire Survey
of the river Aire.The 250m stretch of the River Aire surveyed comprised of Newlay Weir, the riverbanks, foreshore, and flood defenses and was surveyed with no issues due to the USV’s shallow draft and the Geoswath interferometric sonar’s wide swath, which was able to efficiently survey the river bank-to-bank.A topographic survey was also completed to establish the geometry of the riverbank, foreshore, flood embankments, walls and ground behind the defences. For this part of the work Storm used a combination of the SL40 USV and traditional survey techniques, with a total station capturing

Chicago Electric Fish Barrier Safety Analysed
address the risks posed by the barrier’s electrified waters. The electric fish barrier system in the CSSC was built and is maintained by the U.S. Army Corps of Engineers to limit the spread of various aquatic invasive species, including Asian carp, between the Great Lakes and Mississippi River basins. Coast Guard regulations prescribe operating rules and guidance for commercial and recreational mariners transiting the Chicago Sanitary and Ship Canal.
