After a Europe-wide tender, the contract for performance and evaluation of the preservation of maritime evidence program for the JadeWeserPort was awarded to IMP in 2005. Since then IMP has performed and analysed extensive current and turbidity measurements both as long-time series and individual campaigns, processed soundings, analysed morphological developments and examined water levels.
The measurement series was initiated before starting construction of the new port and has been continued throughout the construction phase and into the operational phase in order to capture the lagged morphological response. The preservation of evidence measurements will end as soon as a new equilibrium condition is reached. The gained database will then form the evaluation basis for description and assessment of maritime impacts resulting from the construction. Beyond this, the intense focus of a preservation of evidence procedure does also often contribute to a better understanding of the system in general.
