Slope erosion is most prominently observed in riverbanks, hilly terrain, and other landscapes, posing a significant challenge to environmental sustainability and infrastructure stability worldwide. Traditional erosion control methods often lack sustainability and may have adverse impacts on the environment. This review focuses on investigating the effectiveness of geosynthetic composite mats in mitigating slope erosion while promoting ecological restoration. These composite mats offer a sustainable solution for stabilizing slopes while promoting vegetation growth and ecological restoration. The findings of this review are anticipated to provide valuable insights into the efficacy of geosynthetic composite mats as a sustainable solution for slope erosion control. The impact of the research extends to geotechnical engineering, environmental conservation, and land management practices. Additionally, by integrating technology into slope erosion control measures, this review aims to address the limitations of traditional methods and contribute to the development of environmentally friendly and long-term solutions. The potential applications of geosynthetic composite mats include infrastructure development, riverbank stabilization, ecosystem restoration, highway embankments, coastal protection, and mining reclamation, among others. Overall, this review includes versatile solutions for various terrain types and environmental challenges using geosynthetic composite mats, further enhancing their relevance in sustainable land management practices.
