Tóm tắt

Soil erosion and riverbank degradation pose major threats to ecosystem health and sustainable development of human society. The seemingly effective hard revetment structures have often overlooked the self-purification capacity of rivers. This study experimentally explored the effectiveness of microbial-induced carbonate precipitation (MICP) for mitigating the hydraulic erosion of riverbanks and permeability characteristics of bio-revetment. Erosion tests of MICP-treated sandy soil using the premixing-infiltration technique were conducted with a modified Erosion Function Apparatus (EFA). The erosion resistance of microbially premixed sandy soil did not exhibit the anticipated enhancement due to the limited quantity and ineffective cementation of CaCO
