Shoreline Protection: Dimensioning Blocks, Walls, and Erosion Control Measures

This lecture covers the dimensioning of blocks in riprap shorelines, including empirical formulas and placement techniques. It also discusses the design and construction of protective walls, diaphragm walls, concrete groynes, and other erosion control measures. The instructor explains the factors to consider when choosing between riprap, biological engineering, or protective walls, emphasizing stability, geology, and resistance to scour. Various types of protective structures, such as folded walls and diaphragm walls, are explored in detail, along with their advantages and disadvantages. The lecture concludes with a focus on bed protection, including thresholds, ramps, and energy dissipation zones, to prevent erosion and stabilize riverbanks.
