Abstract:The CoVadem initiative is about cooperative water depth measurement by and for inland skippers. It is a new way in the determination and optimization of vessel routes for the inland shipping sector. A little number of vessels (approximately 75 vessels) have currently joined the initiative and this brings along some obstacles. The vessels do not sail at the exact same location at the exact same moment in time on the river. Therefore, the data from all vessel tracks within a week are combined in grid cells over the domain of the navigation channel of the river. Because of the timescale the morphological processes of a river must be considered. These morphological processes have influence on the grid cell size and the water depth value of this grid cell. In this research an optimal uniform grid size and grid bed level value is investigated by validating this with Multibeam bed level data. Furthermore, a little study is done on the applicability of the validated grid cell size and bed level value to river sections with less data. The hypothesis of an optimal uniform grid size is rejected in this research, but a reliable method is found for the generation of a bed level value in a grid cell. The last conclusion that can be drawn is that the sections with less data can also give reliable bed level values, despite having some gaps in the grid.
