The article discusses a new way to design protective structures for water, like dams or levees. Engineers usually use a step-by-step process to design these structures, with the first step being very repetitive and involving lots of calculations. To make sure the structures are safe, engineers often use expert opinions or safety factors. But using a full probabilistic approach, which considers all uncertainties, can give better insights into safety. The researchers developed a model that uses a method called parametric design to quickly find multiple safe design options for a type of protective structure called a rubble mound slope protection. This new approach helps engineers see more design possibilities faster in the early stages of the design process.
