Due to situation with COVID-19, a meeting was held in Zagreb for the consortium partners which were able to arrive to the venue location. For those unable to participate physically, an on-line participation was arranged.
The activities in obtaining historical data from both case study areas, as well as the existing data necessary for the development of downscaled climate scenarios were presented. It was noted that the input necessary for development of embankment fragility curves are mostly linked to the predicted water waveheights and their duration.
In addition to the situation with COVID-19, city of Zagreb was struck on March 22nd by an earthquake of high magnitude. Due to earthquake, UNIZAG GF was collaborating with Croatian Waters in assessing the condition of 141 km of flood protection embankments, and 19 km of retentions, in wider area of city of Zagreb. The applied assessment methodology has a ground peneetrating radar (GPR) investigations in focus, and it is exactly this method which will be further developed within the WP3 of the project. UNIZAG GF conducted these investigations during March and April, followed by the data interpretation. To increase the assessment potential of this first-pass assessment method, UNIZAG GF currently developes AI-based tools which utilize a pattern recognition technique to search for various types of anomalies within the flood protection embankments.
It was mentioned that the Dutch stakeholders have interest for investigation of the secondary embankments which are in worse condition when compared to primary embankments.
