Due to recent climate changes, the annual flood increment rate has enhanced tremendously in different countries. About 3mm yearly, the sea level is rising as a result of a billion tons of ice melting every year.
Due to the rise in sea levels worldwide, coastal erosion has become a serious concern, causing heavy damage to public properties & coastlines around the world. To prevent the exacerbation of erosion hazards, rapid coastal developments were initiated.
Companies of Geotextile suppliers in India, to address these concerns, both structural & non-structural measures have been employed.
Mitigation of flood risks via structural flood measures like:
- amphibious construction
- permeable pavement
- river dikes
Mitigation of flood risks via non-structural measures contains:
- flood risk management
- urban design
- flood hazard
- community involvement
- official planning
- land use
- flood estimation
- forecasting warning
Being a non-woven geotextile manufacturer in India, in this blog, we are going to highlight flood risk management using geotextile & geotube technology.
Rapid growth in development & renovation emphasizes the importance of coastal construction. Now, structures in coastal regions are constructed bearing the quality & ecological functioning in mind.
In such regions, this is to reduce the environmental threats. In recent times, the unavailability of natural rock & traditional forms of the river has enhanced the cost of construction & maintenance of coastal structures.
Therefore, the requirement for cheaper materials and systems as alternatives has been introduced. Concrete systems & other traditional rubbles are now replaced with cheaper alternatives like geotextile tube technology.
What is Geotube?
Geotextile tubes which are also known as geotubes are long woven polypropylene tubes. They are mainly used as important ingredients for breakwaters and dams, groins, & longshore protection. The sheets of geotextile are permeable, yet soil-tight, in such a way that it drains any excess water from the geotube using various kinds of containers.
As a result of this drainage, the tube height is decreased and requires to be pumped severally in order to achieve the desired height. Also, we have seen geosynthetic containers cases applied as armour, core for hydraulic structures, storage, earth dam improvement, filters, ballast, flood protection, and scour repair & protection.
Environmental Pros of Geotube Technology Over the Traditional Method of Construction
Geotextile tube installation is not just an alternative construction technique but also the most result-oriented solution on the planet. It boasts various beneficial aspects, making it worthy of consideration.
For instance, geotextile installation guarantees +ve environmental impacts as it reduces CO2 emissions during construction operations. A geotextile tube breakwater would also reduce dredge disposal volume as well as excavating & rock transportation to the site.
Overall, the pros of geotextile wall are as follows:
- Reduce the disturbance of biota due to repair & maintenance during the lifetime of the structure
- Reduces fuel consumption & transport of excavated material
- Minimize -ve impacts on extraneous species and habitats
- Reduces overall carbon dioxide emissions in transport & placement operations
- Waste material is utilized as a resource in a beneficial manner
- Reduces excavated material
- Reduces disposal at sea for dredged material
Usually, geotextile when installed as a cheaper alternative to the current measures in place to prevent piping has resisted failure.
Geotextile fabric manufacture in India, comparing geotextile tubes and traditional methods, the geotextile tube system produces over 85% less carbon II oxide when compared with traditional rock structures.
Thus, utilizing geotube technology is a more economical method of breakwater construction. More so, it provides a better environmental alternative to traditional breakwater systems.
