Investigating Soil Internal Erosion and Seepage Mechanisms

This report provides a comprehensive overview of soil internal erosion and seepage mechanics, focusing on their impact on dam safety and stability. It delves into various aspects, including concentrated leak erosion, backward erosion piping, suffusion/suffosion, and stoping, explaining the underlying mechanisms and potential failure modes associated with each. The report also discusses a risk-based approach to evaluating internal erosion, highlighting the phases of internal erosion (initiation, continuation, progression, and breach) and their contributing factors. Furthermore, it emphasizes the importance of filtration in preventing continued erosion and presents methods for assessing dam filters. The report concludes by underscoring the need for effective remediation measures to mitigate the risks posed by internal erosion and seepage in dam structures. This document is available on Desklib, a platform offering a wide range of study tools and solved assignments for students.
