Periplus in action on the Dutch rivers and the Wadden Sea – April 2011
Investigation River IJssel
Periplus Archeomare B.V performed an archaeological field investigation in the river IJssel between Zwolle and the Ketelmeer, using high resolution side scan sonar data. The investigation was performed for DHV Coastal and River Development and was deemed necessary because scheduled deepening of the riverbed could potentially result in loosing archaeological valuables. During the investigation a number of objects were located that would require a closer research by dive inspection. This underwater investigation will be performed in April 2011 in cooperation with ADC ArcheoProjecten and Subcom (Diving Services).
Monitoring of mussel farming activities
Since 2010, Periplus Archeomare B.V. is conducting an annual monitoring project in the Dutch Wadden Sea to investigate the influence of mussel farming (mosselkweek) activities on the underwater environment. There are a number of historically important ship wrecks in the area that could be damaged by a potential changing erosion and sedimentation pattern. During the first investigation all known ship wrecks as well as possible remnants of previously undiscovered wrecks were located and mapped. The project will run till 2012.
Archaeological research in the River Vecht
Between 2007 and 2011, Periplus Archeomare B.V., in conjunction with ADC ArcheoProjecten and Subcom, performed several Archaeological research projects in the river Vecht between Muiden and Utrecht for Waternet. During those projects several objects with considerable cultural heritage value, like ancient ship wrecks and water lock system dating back to the 15th Century, were found and further investigated. In April 2011, remediation works of the river Vecht will commence for which Periplus Archeomare B.V. will provide advisory and consultancy services in order to warrant preservation of archaeological valuables for the future.
