A method is presented for determining wave runup on composite slopes of different roughnesses. This method is one of successive approximations and involves replacement of the actual rough composite slope with a hypothetical single slope extended from the breaking depth and an estimated runup value. Design data on the height of runup are needed to determine crest elevations of protective structures subject to wave action such as seawalls, revetments, and dam embankments. These elevations are important from both functional and structural considerations.
