We have attended a meeting on November 5, 2015, with partners of Deltares and of the Korea Institute of Civil Engineering and Building Technology (KICT) to discuss near-future cooperation. All parties are interested in spatial monitoring of aquatic vegetation, for hydraulic purposes and for aquatic-ecological aspects. Water managers deal with this vegetation in a way that it is on one hand serving ecological targets (EU WFD), but on the other should not hamper the water transport capability of brooks, channels, and rivers. Reduced water transport capability can possibly lead to summer floods. We want to look at monitoring techniques, combining field and ground-truth measurements with remote sensing or airborne sensing. The KICT River Experiment Center (REC) could be useful for test purposes.
