Methodology for the estimation of morphodynamic evolution of the “El Puntal” Universidad de Cantabria (UCa) http://www.gioc.unican.es Autoridad Portuaria de Santander
The bold questions refer to the strategic objectives, while the normal questions refer to the operational objectives. - The questions addressed are first prioritized for the Spanish situation at El Puntal Spit. Strategic objectives are ordered to their importance: *** means high importance, * means low importance. - Normal questions are referred to the end user involved/interested: 1 Santander Port Authority – 2 Ministry of Environment – 3 Municipality of Somo and Santander The CSIs are also ordered to their importance: *** means high priority, * means low priority. The final CSIs for El Puntal Spit are underlined. The ARGUS input is classified to its degree of success. 1 means easy to execute and leading to a good result, 4 means difficult to determine (technology not available at present) and probably difficult to reach a success within the time of the COASTVIEW project. The final decision of the selection of CSIs is also based on the ARGUS input and Field measurements (ground-truth) possibilities.

The video techniques used to achieve the period of dredging and the volume are: • The first techniques is called time-stack and provide the period of dredged with the morphological evolution of cross-shore profiles. • Furthermore, the volume of dredged is fixed with mapping intertidal bathymetry technique. http://www.gioc.unican.es
