Abstract: In September 2008 the start of Maasvlakte 2 was officially celebrated.
In January 2009 the fist TSHD started her activities. At the end of 2009 a large portion of the sand volume required for the construction will be put in place. It is anticipated that at that time 6 to 8 TSHD will be working around the clock (7/24 format). The extensive baseline surveys and studies, carried out prior to the start of the works, are followed by actual monitoring. Some findings and details of ongoing monitoring will be presented.
Underwater sound in front of the future MV2 near the entrance to the Port of Rotterdam was measured in 2008. In the fall of 2009 all specific stages in the working cycle of the TSHD's will be measured, resulting in so called source levels. Prior to the start of the project baseline studies were carried out; Benthic, Silt profiling, Juvenile Fish. In 2009 and the years thereafter Benthic and Silt profiler surveys will be carried out again. Not all monitoring will be physically in the field, as the use of numerical models and data assimilation with remote sensing is carried out as well. A new development program was started at the end of 2008 as a follow up of the pilot project : ToTSM: Integration of Remote Sensing and Modelling of Total Suspended Matter in the Dutch coastal zone, Deltares&IVM. The state of the art with respect of the modelling for MV2 and the integration of the field data will be discussed and presented.
