摘要：Cascade aeration has been utilized as a hydraulic structure for years which has proven to be the least costly aeration system in replenishing dissolved oxygen. The aeration performance of the cascade structure with end sill has been investigated in a large laboratory cascade structure which has been designed and constructed at Al- Mustansiriya university in environmental hydraulic .An empirical equation to predicting the oxygen transfer efficiency for different models of cascade structure with end sill was correlated. The results indicated that l/h and s/h were a significant effect on the aeration efficiency of cascade structure.
