Abstract :

In this laboratory study, the longitudinal changes of the flooring to the depth of the downstream scour of Calvert (square calvert shape), the changes in the length of the flooring to the depth of scour downstream of the calvert are discussed. For this purpose, experiments were performed on the floor with different lengths. According to the results, 22%, 33% and 66% were observed in particle 2 landing, 15%, 20% and 40% in 2.5 particle landing, respectively, and 20% and 25% in particle 3 landing, respectively. And reduced scour depth by 31%. This showed that changes in floor length and characteristics have a positive effect on the scour depth downstream of Calvert. Therefore, all these results have been studied in the laboratory environment and are real numbers and have been taken on a small scale.
