Helping to Keep Waterways Navigable in the Netherlands

Maintaining the narrow navigational channels through the shallow tidal flats of the Wadden Sea in the Netherlands is a constant battle, due to the high rate of sediment deposition. Nortek’s Signature VM instrumentation has proved to be a valuable weapon in this fight, providing vital information on particle density and current flows through the water layers.The Dutch jokingly say that God created Earth, but the Dutch created the Netherlands, given the extensive measures taken through the centuries to reclaim and protect the country’s low-lying land from the sea, largely through the construct

New Water Level Measuring Stations in the Wadden Sea

The Wadden Sea is an intertidal zone that lies between the coast of northwest Europe and the low-lying Frisian Islands. It consists of a shallow body of water with tidal flats and wetlands. Listed as a UNESCO World Heritage site due to its diverse nature, it is an area of strict environmental conservation.MacArtney has delivered six measuring stations to a German energy supplier in May this year including six Tide Masters designed by British manufacturer Valeport, equipped with Data Telemetry Units. The Tide Master device acts as a water level recorder; it can accurately record the height of the water

now consists solely of natural flow, will be expanded with new pumps.  Levvel’s discharge solution consumes as little energy as possible: ‘Natural discharge if possible, pumping if necessary.’ This way, in the future, sufficient water can be drained from the IJsselmeer to the Wadden Sea in all weather conditions.  For the construction of the new pumps and the extra discharge capacity, the existing monumental 'Spuisluizen' (drainage locks) in Den Oever remain completely intact and they will be renovated. Levvel strengthens the dyke with innovative concrete elements. The innovative

; says Mathias Heckroth, Managing Director of Mellumrat e.V., an NGO dedicated to conservation and scientific research of the uninhabited island of Mellum, one of the 32 Frisian Islands in the North Sea expanse being studied by the University of Oldenburg team. Mellum is situated in the intertidal Wadden Sea, a UNESCO World Heritage Site protecting more than 10,000 species of plants and animals, and where up to 12 million migrating birds spend time each year.   “The study is playing an important role in helping to identify the source of the plastic litter. It is also showing unexpected

Boskalis to Reinforce Houtrib Dike

from flooding. During storms, the dike prevents water from the IJsselmeer lake flooding into the Markermeer lake. The dike however currently does not meet the government safety standards. As part of the Dutch Flood Protection Program, Boskalis is currently also working on the reinforcement of the Wadden Sea dike on Texel, the reinforcement of the Wadden Sea dike between the towns of Eemshaven and Delfzijl, as well as making this dike earthquake-proof, and the reinforcement of the Markermeer dikes between the towns of Hoorn and Durgerdam.

Boskalis to Reinforce Wadden Sea Dike on Texel

Royal Boskalis Westminster N.V. (Boskalis) announces that the Hollands Noorderkwartier district water board has awarded the contract to reinforce the Wadden Sea dike on the Dutch island of Texel to "Combinatie Tessel", a consortium consisting of Boskalis and KWS, a VolkerWessels company. The contract carries a value of EUR 70 million, of which Boskalis' share is EUR 50 million.   Large parts of the Wadden Sea dike on Texel currently do not meet legal safety requirements. The flood defences need to be reinforced to meet these requirements in the future.   The project involves

. The data management system will acquire the measurement data collected during the research cruises of RV Mya II. It will also archive and centrally provide the measurement data on shore at the AWI. Being stationed on the German island of Sylt, RV Mya II will go on one-day research cruises on the Wadden Sea and on the North Sea up to Helgoland. RV Mya II is 21 meters long and, thus, the smallest research vessel Werum's DSHIP data management system is used on. The vessel is equipped with a variety of measuring instruments and sensors as they are also installed on larger AWI research vessels. Now
