The word "溃坝" is formed by combining the character "溃", meaning to burst or collapse, which includes the water radical (氵) suggesting a relation to liquids, with "坝", meaning dam, which includes the earth radical (土) indicating an earthen structure. In this compound, "溃" acts as the verb describing the action, and "坝" serves as the noun specifying the object, resulting in a direct literal meaning of "dam burst" or "dam collapse".
