During planning approval, additional measurements became necessary as part of monitoring the building construction as well as after finishing construction to form a basis for validation of model forecasts and for documenting conditions after the extension. IMP conducted, analysed and evaluated these measurements too from 1998 to 2002.
During these assessments of ship induced exposures, IMP developed a computer-aided analysis approach. This approach for the first time enabled analyses of several thousand ship passages, thus forming a sufficiently large data base for statistical assessments of ship-induced exposures. This analysis approach, published by SPINGAT (1999), since then provides the basis for assessing ship-induced exposures for all German sea waterways.
