Devbagh is a small fishing village which sits on a thin strip of land with the Karli River backwaters on one side and the Arabian Sea on the other. Devbagh Beach is adjacent to Tarkarli Beach and ends at Devbagh Sangam. It is easily accessed via the Malvan-Tarkarli road. Devbagh beach is less crowded during the high tourist season and attracts tourists looking for peace and relaxation.
A point marks as the confluence of the Karli River flowing into the Arabian Sea, is the southernmost tip of the malvan taluka. An interesting geographical site, it is far more enchanting to see it atop the bridge built to cross over the river into Vengrula.
There is a risk of erosion of beautiful beach at the confluence of Karli River with Arabian sea. Client was looking for a solution to reclaim the beach.
Groynes are invented to slow down long shore waft and build up the beach. They are constructed at right angles to the shore with spacing about 50 – 100 meters apart so that they efficiently absorb the energy of the waves. Earlier days, they were typically made of tropical hardwoods or concrete. They are used to prevent coastal erosion by restricting the sediments, sand and debris from getting into contact with the shoreline. TechTubes are advanced and effective usages as Groynes for beach nourishment.
Devbagh Beach, located at the confluence of the Karli River and Arabian Sea, faced erosion risks due to strong wave action and sediment movement. Protecting and reclaiming the beach was essential to preserve its natural beauty and safeguard tourism potential.
The dynamic coastal environment, influenced by river inflows and sea currents, caused shoreline erosion. Conventional methods like stone or concrete groynes were costly, environmentally disruptive, and difficult to mobilize.
TechFab India proposed TechTube Groynes — advanced geosynthetic tubes installed perpendicular to the shoreline. These structures slow down longshore drift, trap sediments, and build up the beach naturally.
TechTube, designed for coastal protection and beach nourishment applications.
The TechTube groynes successfully reclaimed and nourished Devbagh Beach, stabilizing the shoreline and enhancing its resilience against erosion. The solution preserved the beach’s natural environment and supported tourism development.
By applying innovative geosynthetics for coastal protection, TechFab India demonstrated its ability to deliver sustainable, cost‑effective, and high‑performance solutions for sensitive environments like beaches and river confluences.
