Evaluation of the efficiency of geosynthetics as a solution for riverbank defenses in La Leche river, Lambayeque, Peru

Marketing Paragraph: Statement of Purpose: The study evaluates the implementation of innovative geotechnical solutions—geoboxes combined with anti-scour blankets—along the La Leche River in northern Peru, a region severely impacted by El Niño. These adaptable and cost-effective materials demonstrate exceptional performance in mitigating erosion, enhancing slope stability, and reducing environmental impact. By integrating local resources and advanced engineering design, this approach offers a sustainable and scalable solution to safeguard vulnerable communities and infrastructure.

Full Abstract: Complete Proposal for Your Session:Riverbank erosion significantly threatens ecosystems, infrastructure, and local communities, particularly in regions affected by extreme climatic events such as El Niño. This research evaluates the application of geosynthetic solutions—geoboxes and anti-scour blankets—implemented along the La Leche River in northern Peru. This region experiences severe flooding and erosion, exacerbated by the intense rainfall and flow variations associated with El Niño.

The study integrates slope stability analysis, and post-installation field evaluations to assess the effectiveness of geosynthetics in controlling erosion and mitigating the impact of extreme hydrological events. Results demostrate that geosynthetics provide a sustainable and cost-effective solution for riverbank protection. Their adaptability to dynamic flow conditions, ease of installation, and reduced environmental impact make them a practical choice for erosion control in vulnerable regions. The geoboxes, filled with locally available materials, and the anti-scour blankets, designed to prevent toe erosion, collectively enhance slope stability and ensure long-term durability of riverbank defenses.

The adaptability of geosynthetics to dynamic hydrological conditions ensures their performance under extreme circumstances, as evidenced by their ability to withstand the challenges posed by the most recent El Niño event in 2023. The project not only highlights the efficiency of these solutions but also underscores the importance of thorough design and implementation processes that account for site-specific hydraulic variability.

This presentation offers an in-depth analysis of the methodology used, including site characterization, geosynthetic material selection, and implementation strategies. Attendees will gain valuable insights into the practical application of innovative materials for riverbank defense, as well as the broader potential of these technologies to address erosion in high-risk regions.
