PROJECT SAMUT PRAKAN - NSTDA

The National Science and Technology Development Agency (NSTDA), the National Electronics and Computer Technology Center (NECTEC),

Kasetsart University, and Arto Wood (Thailand) Co., Ltd.

collaborated to study the use of CAOS artificial mangroves by installing a prototype test site at Bang Pu Recreation Center, Samut Prakan Province, in September 2015.

Installation Results
The U-shaped installation, implemented since September 2015, has proven effective in reducing wave impact perpendicularly to the shore. It has accelerated sediment accumulation behind the artificial mangrove structures, resulting in a continuous buildup of sediment, which compacted by 20 cm within 4–5 months. Water and sediment quality, both before and after installation, remained within normal parameters. The levels of heavy metals in the sediment were within safe limits, posing no pollution risks to aquatic life, and benthic organisms continued to thrive. Even after 10 years of installation, the materials remain in good condition—strong and durable. The accumulated sediment behind the artificial mangrove installation has expanded by approximately 5 rai (8,000 square meters), allowing for mangrove reforestation and the restoration of the coastal ecosystem.
