  HESCO Barrier  Implementation Cases  ​ ​1. River Ecological Restoration: Srepok Riverbank Stabilization, Vietnam (2024)​ ​ ​ ​Challenge​ ​: Monsoonal floods caused 15m/year of bank erosion, endangering farmland and villages. ​ ​Solution​ ​: Deployed ​ ​2.1 km of  HESCO barriers ​ ​ (30° water-facing slope) filled with volcanic rock (70%) and recycled rubber granules (30% for fragmentation absorption). Seeded ​ ​vetiver grass​ ​ through barrier gaps; roots reached 3m depth, enhancing soil shear strength. ​ ​Ecological Monitoring Data (18 months post-deployment)​ ​: ​ ​Metric​ ​ ​ ​Pre-Intervention​ ​ ​ ​Post-Intervention​ ​ ​ ​Change​ ​ Bank erosion length 15m/year 0 100% control Fish population density Baseline 100% 135% +35% Water turbidity (NTU) 45 28 -38% Native vegetation cover 12% 68% +467% ​ ​Mechanism​ ​: Barrier pores trapped sediment while vetiver roots stabilized soil, achieving sedimentation at 8cm/month.  ​ ​2. Mining Area Restoration: Hüsamlar Cop...
