Working packages:

WP 1: Investigation of degradation processes of geosynthetics in hydraulic engineering (WP leader: BAM):

• Artificial/accelerated ageing (UV, thermal, high-pressure autoclave testing, elevated salt concentration);
• Degradation/ageing enhanced by microbiological activity;
• Simulation of exposure in the engineering application (mechanical and combination of above mentioned);
• Case study: Environmental impact of application of geosynthetics at Kaliningrad shore.

WP 2: Release from geosynthetics under application conditions (WP leader: LIAE):

• Leaching tests with geosynthetics;
• Ecotoxicological assessment;
• Numerical simulation of microplastic (MP) particle transport (influence of biofouling).
