Management measures analysis and comparison


by S. Saathoff, J. Knüppel, S. Manson & A. Boerema

7a. Procedure

Measures have been selected and compiled for comparative analysis. The measures selected were those that it was judged were well documented, and that had the potential to be educative as a consequence, for future measure planning and implementation in the light of the measure categories and development targets (3 categories and 13 development targets). Overall 39 measure examples have been selected most of them belonging to the categories Biology/Ecology (25) and Hydrology/Morphology (9). Only two measure examples have been addressed to the category Physical/Chemical Quality, three examples have been allocated to two categories each. The Elbe is represented by 12 measures, Humber by 10, Scheldt by 11 and Weser by 6 measure examples. For all these measures fundamental and extended information has been compiled according to an agreed scheme.
The comparative analysis focused on the effectiveness of a measure in view of different aspects and targets: initial development targets, ecosystem services (ES), Natura 2000 objectives, Water Framework Directive objectives. In addition, lessons learned were collected and gaps in knowledge were identified, partly by involving the organisations in charge of measure planning and implementation. The set of analysis criteria was defined in consultation with all TIDE partners. The analysis process was based on the contents of the measure surveys followed by a more detailed, goal oriented analysis of available monitoring reports and/or modeling results as well as expert knowledge.
Additionally cross estuary comparison focusses on two significant aspects - managed realignment measures and the control of sedimentation processes.

Report: Management measures analysis and comparison

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?
