The proposal for measure 2.2 of the BEACHMED-e project includes five public research bodies, belonging to three countries within the European Union, and four different regions which will work together for 24 months. This project aims to study the dynamics of the coastlines and their consequences by focusing on the four scientific research areas shown below: 1. Characterisation of wave climates and hydrodynamic and weather conditions based on measurements and modelling. 2. The study of erosion and sea storms in coastal zones. 3. The study of deterioration processes of artificial coastal protection mechanisms and the development of methods for the monitoring and prediction of their behaviour. 4. The study of interaction between wave movement and marine biotopes (samples of Posidonia oceanica grasslands). These features will be studied in a number of sites located throughout the various partner regions. The sites that will be studied will mainly consist of sandy coastlines, along with any artificial coastal protection structures and/or Posidonia oceanica grasslands. The management of these features will be mainly based on the valid assessment of coastal hydrodynamic factors for the zones under analysis. Work carried out by the research team will therefore all have to be carried out using numeric modelling and on-site measurement of coastal hydrodynamic and hydrosedimentary processes. Partners have also adopted the same methodology which has been summarised below: 1. Selection of study sites based on issues being analysed and bibliographical summary of hydrodynamic data and other data available at these sites. 2. Organisation and implementation of campaigns aimed at hydrodynamic measurement based on various temporal and spatial scales at these sites. 3. Modelling of hydrodynamic, hydrosedimentary and/or hydrobiological processes validated and adjusted according to existing measurements and/or measurements gained at the sites taking part in the project. 4. Implementation of ad hoc products for the various issues being analysed: Hydrodynamic atlas of the coastline (erosion and sea storms), establishing CSI (Coastal State Indicators), maps showing Posidonia oceanica dynamics and summary documents. 5. Implementation (or updating) of databases and websites, in order to allow for archiving of obtained data and modelling results. This will create core documentation which can be quickly accessed by those in charge of managing the coastlines.
