THE EBRO DELTA - MORPHODYNAMICS AND VULNERABILITY

The aim of this paper is to provide an assessment of a vulnerability c oncept for real deltaic ''applications'' using the latest available kn owledge on processes and dynamics for the Ebro delta. The building blo cks are the morphodynamic components, which are presented in terms of field observations, supplemented by numerical predictions at three tim e scales, and the vulnerability concept, which is quantified in terms of resilience and susceptibility using the morphodynamic information. The approach is then illustrated (in conceptual and quantitative terms ) at long- medium- and episodic-time scales. The paper concludes with a discussion of the application of the vulnerability indices and how t o use this knowledge on processes for more complete deltaic management .
