In the last decades, the technology of dam protection has undergone major advancements. The increasing demand for safety in modern society has created the need for cost-effective measures to protect critical infrastructure such as dams. This situation has resulted in the drafting of new regulations and technical manuals in countries like Norway, Sweden, and the USA, among others. Dam... Read more
