Europe’s coasts face accelerating erosion from sea-level rise, storm surge, and subsidence. Between 2025 and 2030, Germany and Europe will scale a dual toolkit: (1) engineered geotextile systems (tubes, sand containers, geogrids, geocells) that rapidly stabilize shorelines and protect infrastructure; and (2) nature‑based, hybrid solutions (dunes, beach nourishment with nearshore bars, salt‑marsh/mangrove revival in suitable climates) that restore sediment dynamics and dissipate wave energy. The strategy mix is site‑specific exposure, bathymetry, sediment budgets, ecological constraints, tourism values, and maintenance windows all shape selection and increasingly multi‑phase: quick‑win stabilization followed by long‑life hybridization. Geotextile systems deliver speed, modularity, and attractive unit costs per protected meter, with lower embodied carbon than concrete seawalls. Designs include shore‑parallel tubes for wave attenuation, geotextile sand containers integrated into revetments, and geocell confinement to resist scour.
