Before & After Installation

Working together with Thai Wiring Systems, our partner in Thailand, we completed a demonstration project for Derosion Lattice in September 2021. The Marine Department of Thailand oversaw the project, with the intent to fix the “end effect” (or “terminal scour”) problem that occurs at the end of a rock revetment or seawall. Many coastlines in Thailand face severe erosion due to strong monsoon waves, and the end effect issue is present in different areas. In the next few months, precise measurements will be made to monitor the progress of sand accumulation after the installation of Derosion Lattice.

ReShore Technologies was happy to collaborate with Thai Wiring Systems, the Aquatic Resources Research Institute of Chulalongkorn University, and the College of Advanced Manufacturing Innovation of  King Mongkut’s Institute of Technology Ladkrabang on this project. More data and pictures of the results achieved will be updated on our website throughout the next year.

Our project site in Songkhla, Thailand – the area indicated in yellow indicates severe “end effect” at the end of the rock revetment. The beach eroded so far that trees were being washed into the sea.

We began with clearing away the trees and debris in the installation area.

Below are survey results of the surrounding beach area, in the range of 300m x 25m next to the Derosion Lattice installation.

In the total area of 7500 m², the total volume of sand accumulated is 7356 m³, and the average height increase is 7356/7500 = 98cm.

Difference between 1st and 2nd survey

Beach profile measurements were taken for the 50m x 30m area around the installation. The different colored lines on the six profiles show steady increases in elevation, from 8/13/2021 (prior to installation in September), to 11/20/2021 (2 months after), 4/30/2022 (7 months after), and finally 5/20/2022 (8 months after).

Note: Some basin parts on the beach increased by 70cm to 140cm in sand depth. Overall the beach is now very even in elevation throughout the measured area.
