TIDE considers tidally influenced NSR estuaries with large sediment transportation, which are used as shipping channels to large harbours. All of them face the same type of increasing problems for which they need to find win-win-win solutions addressing economic, ecological and social needs. TIDE will lead the path towards a more sustainable and effective use of large scale investments made into mitigation and compensation measures in NSR estuaries by applying for the first time a unified ecosystem approach to guide the process of integrated participatory management planning.
