For evaluating the hydraulic safety of a dam, an accurate evaluation of the hydraulic capacity of the spillway is most needed. Because almost existing small dams have been used the empirical discharge equation, it made some discharge trouble at the dam in flood. This study is showing a case study of evaluation method of morning glory type spillway that is required the best of care and is comparing new capacity with existing.
