EXPERIMENTAL AND NUMERICAL MODELLING OF HYDRAULIC STRUCTURES

Abstract: Each hydraulic project, which is a sub-division of civil engineering requires that the building to be constructed be designed differently according to the topography and climatic conditions of the intended purpose and the region to be constructed. These conditions cause each water structure to be unique and to be projected differently. In the process of designing hydraulic structures, it is not possible to define the entire parameters affecting the project mathematically, so it is possible to avoid the mistakes and find the most appropriate solution in these structures, which are very expensive to construct, only through physical model studies. The problems that can be seen in the construction completed and opened to operation can be caused by loss of life and property which cannot be compensated. The compatibility of experimental studies with mathematical models in hydraulic studies is a large measure of the accuracy of the study. The differences that arise from this may be due to scale effects in experimental work, errors that may arise from measurements, errors in computation, while in mathematical modeling, simplification of the phenomenon results from acceptance made with purpose. As a result, any modeling within the possibilities before the construction of the hydraulic structures is important in terms of preventing actual damages, life and property losses. In this study, experimental and numerical study of a dam spillway will be presented. Differences and similarities are shown.
