1. Aim of the study

The aim of this TIDE study was to collect, analyse and compare examples of practical management measure planned or realised in the Weser, Humber, Elbe and Scheldt estuary (hereinafter called TIDE estuaries). The results of this exercise should be used to exchange experience and to improve future planning and implementation processes of estuarine management measures.
A set of well-documented and educative measures aiming at different development targets was selected for the analysis. It was based on a set of criteria which was executed for each measure example and which founded the basis for an in depth comparison of measures in terms of certain aspects of interest (e.g. measures influencing sedimentation, managed realignment measures). As an overall result, recommendations addressed to estuary managers in view of future measure planning and implementation processes were formulated.
Additionally, this report contains a list of the pilot projects realised at the estuaries of Weser, Elbe, Humber and Scheldt during the runtime of TIDE. The pilot projects primarily address a question of specific interest in view of the estuary they refer to, but they also provide results transferable to other estuaries of the North Sea region.

Management issues

How and by which management measures can tidal amplification be reduced?
How can public acceptance for management actions be increased?
How can the Ecosystem Services Approach be used to support management decisions?
How can we assure accessibility to an inland estuarine port without affecting the habitats and safety against flooding?
How can we prevent excessive degradation or loss of tidal marshes?
How does habitat management affect the supply of ecosystem services?
What are the key areas of conflicts or synergies in TIDE estuaries?
What are the restoration opportunities for side branch systems and river banks (e.g. left side branch Weser)?
What factors determine the distribution of suspended sediments in an estuary?
What measures are successful for the dissipation of tidal energy?
What monitoring is required to support and assess management decisions?
What parameters should be used to define and evaluate measure targets?
What tool is available to help manage multiple users of a resource in an integrated way (i.e. achieving more holistic management)?
Which aspects do I have to take into account in order to make a measure a success?
Which measures are suitable to achieve specific ecological targets?
Which measures are suitable to achieve specific morphological and hydrological targets?
Which measures are suitable to identify, protect or develop valuable submerged habitats e.g. mussel beds and Sabellaria reefs?
Which measures are suitable to improve the physical characteristics and chemical water quality?
Which measures are suitable to provide ecosystem services and benefits?
Which synergistic effects and conflicts can be expected by planning and implementing a certain measure?
