Innovative cubing of dams and dikes with earth-filled geotextile tubes for improved flood protection
Brief description of the project:
Flood protection systems are required for effective flood protection to safeguard industrial, commercial and residential areas as well as landscapes.
Modern flood protection also takes the climatic changes over time into account and is sustainable and resource-savingat the same time.
The advantages of topotubes, soil-filled geotextile tubes, are to be used in such a way that slender cross-sections with lower material and area requirements,
higher material variance and higher resistance to hydraulic loads. At the same time, the design provides overflow protection and
resilience to changes in design conditions after construction, such as flood occurrence probabilities and water levels.
In the project, the limits and thus maximum advantages of the system are specifically explored by experimental and numerical investigations. The proofs will be provided by targeted monitoring. The results of the project are to be translated into general design guidelines that fully exploit the advantages of the new construction method and, by means of the systematic description, benefit a broader stratum of users in the field of hydraulic engineering and dike/levee construction.
