Filters for Embankment Dams - Design & Construction – Part II

This online engineering PDH interactive presentation provides a detailed exploration of filter and drainage systems for embankment dam design and construction, emphasizing their critical role in dam safety and long-term performance. It covers core topics such as filter design principles, gradation criteria, material quality evaluation, construction practices, and quality control procedures. The presentation highlights best practices for preventing internal erosion, ensuring material compatibility, and achieving reliable filter performance under various field conditions.

This presentation begins by explaining the function of filters in embankment dams and the risks associated with improper design or material use. It delves into gradation design procedures, laboratory testing techniques such as the NEF and CEF tests, self-healing evaluation methods, and compressive strength testing for filter cohesion. Participants will gain insights into key construction considerations, including placement strategies, moisture control, compaction methods, and avoidance of material segregation. Additionally, the presentation covers real-world case studies, sampling methods, borrow source selection, and guidance on ensuring long-term filter performance under hydraulic and seismic stress.

This 4 PDH online interactive presentation is designed for dam safety professionals, geotechnical engineers, project managers, and civil engineers aiming to enhance their knowledge of filter systems in embankment dams, reduce failure risks, and ensure resilient dam infrastructure.
