Abstract: Implications of the KIER-besluit for the region (salt intrusion), nationally (improved fish migration in the mouth of the river) and internationally (towards germany). Highlights of a new project focusing on connecting reginal waters with the Nieuwe Waterweg Rotterdam; how are regional waters connected with the mainstream throughout the Rhine river basin (Masterplan Migratory Fish, crucial to Eel migration), how are the Meuse and Scheldt commission involved? How is the WFD and fish migration used as a driver for funding some flood schemes in the UK.
