Stormwater Fundamentals Series — Scour Protection: Design of Rock Pads

This webinar, held on 17th June 2026, was session #8 of the 2026 ‘Stormwater Fundamental’ series, and focused on the design of rock pads for scour protection. In this session, you will learn the principles behind bed shear stress, stability of rock, and how to size rock for scour protection at pipe outlets. The session covers key parameters such as flow velocity, tailwater, and anchoring considerations before stepping through worked examples that demonstrate when and how rock is required to prevent erosion. This 60-minute session includes: • Easy-to-follow instructor-led training • Theory linked to practical real-world examples • Worked examples with step-by-step calculations
