Coastal Protection Barriers: Ecobarrier Geosynthetic Containers (geotubes)

Alternative coastal protection structures using Geotextile Sand Containers (GSCs) are increasingly being designed and constructed both in the UAE and regionally, mainly because of their performance in different construction works and environmental benefits. This is as opposed to natural materials, such as rock, to protect the coastline.

Ecocoast built an online GSC calculation tool to assist consultants in the tendering process. The calculator enables them to create graphs from their own data, offering different scenarios that assess waves, GSC size and stability, in order to provide a ballpark estimate for the project to their clients.

The calculator shows the GSC size relationship with wave height, including a comparison between different models (Wouters versus Oumeraci et al.) and behavior between slope and crest (Oumeraci et al.), in order to create a stable structure and get maximum performance. All calculations are based on pre-defined dimension ratios, providing armour unit dimensions (influence of double layer still to be investigated).

With this free online tool, consultants can do their own calculations in less than 10 minutes, saving them a considerable amount of time.

The online calculation tool was designed and engineered by Aleksa Cavic, Technical Engineer at Ecocoast. In explaining the reason for developing the calculator, Aleksa mentions: “My goal was to help consultants with the initial design for their clients, enabling them to assess stability and feasibility of the structure they are proposing.”

The calculator can be accessed here: ecocoast.com/calculator. If you would like to know more, please contact Aleksa at +971 4 885 3944.
