Flood & Sediment Management

The main goal is:
i) present the results of the ex ternal study “Sediment Im balances in European Deltas and Estuaries” elaborated by Tecnoambiente in collabora- tion with IRTA- Aquatic Eco systems;
ii) discuss and define the work plan for each delta/estuary based on the policy recom- mendations.

The external study was focused on:

1) To analyze the present situa- tion of sediment imbalanes in the Danube, Ebro, Elbe, Minho and Vistula Deltas;

2) To identify main problems in these systems;

3) To propose actions from good practices, policy recommendations and current management plans.

The main problems of the DeltaNet systems could be summarized as follows:

a) Sediment retention in reser- voirs, especially in the Danu- be, Ebro and Vistula with a high risk of coastal erosion and flooding;

b) Sediment aggradation in river channels and estuaries, mainly in the Elbe and Vistula estuaries;

c) Chemical contamination of sediments, essentially in the Elbe and Vistula as well as in the Ebro;

d) Flooding Risks, primarily in the Danube and Vistula systems. In addition, the current management measures of each DeltaNet system is presented, and general policy recommendations discussed among the participants of the Workshop.

As a general conclusion, partners agreed that there is a need to integrate flooding risk management plans and sediment management plans, because in most of cases the sediment imbalances are leading to an increase of flooding risks or coastal retreat. Overall DeltaNet partners agree in that it is time “to stop working against nature and start to work with Nature”.
