Case Study
Eroded River Bank
There are Three noticeable areas of erosion along the river embankments in Singapore, Kallang River @ Bishan – Ang Mo Kio Park (KRBAP) causing by scouring due to river flow and the burrowing of fishes. As the river is already live, it is difficult to repair these rivers embankments and allow the newly planted plants to establish. Often, newly backfilled soil gets washed away by flow due to heavy rain event before the plants establish. Therefore, it is recommended to utilise a soil system with high structural stability than loose bare earth to stabilise the banks and allow plants to grow over the bags. This project aims to test-bed the Soil Chain™ system, a sustainable retaining and bank stabilisation system, on its ability to protect riverbanks at areas of higher velocities ad flows from sourcing while allowing the establishment of plants.
This test-bedding exercise created a benchmark for Soil Chain™ greenbag system LW model to be considers on future Public Utility Board’s construction or restoration design specifically on water embankment areas, which has been proven of its unique while seamless solution, where it is truly ecological and sustainable. It further proven that the product and its innovative construction method does not require of using any heavy machinery that tremendously reduces pollution and green-house gases emission throughout the restoration process on all Three eroded sites along Singapore, Kallang River @Bishan-Ang Mo Kio Park, which have currently strengthen these embankments. Planted vegetation was also well established, and capable to sustain with high water flow within the river.
Most importantly, this geological, environmental and biological engineering invention does not produce any construction waste or pollution like any other conventional products or its methods throughout it construction process.
