TY - JOUR N2 - With the emergence of climate change and the increasing human intervention in the global climate, floods have affected different parts of the world. In practice, floods are the most terrible natural disaster in the world, both in terms of casualties and financial losses. To reduce the adverse effects of this phenomenon, it is necessary to use structural and non-structural methods of flood risk management. One of the structural methods of flood control is to allocate a certain part of reservoir dams to flood control. In order to safely exit the flood from the dam reservoir, the spillway structure should be used. One of the important issues in designing a spillway structure is reducing its construction costs. In order to safely exit the flood with a specified return period from the dam reservoir, as the length of the spillway decreases, the height of the water blade on the spillway increases. In other words, decreasing the spillway length increases the height of the dam and its construction and design costs. In this study, the design and comparison of the performance of two glory spillways and lateral spillways have been considered. The results showed that for a given length for the drain edge of both types of spillways, the height of the water blade on the glory spillway is always higher than the lateral spillway. For example, when a 10,000-year-old flood occurs, it is about 8 m.
