Numerical Modelling of River Training Work: A review

Abstract

Abstract The construction of river training structures has a local influence on hydraulic and sediment regimes. River training is simply to modify the dimensions and patterns of channels, bars, and pools. Many scientists have applied and developed methods to identify suitable techniques for river training. In this paper 60 scientific papers were reviewed, and through this review, the researchers were divided according to the method of using the model and according to the problem that the researcher addressed, as 22% of the researchers tended to solve the sediment problem using the HEC-RAS model, and 45% of the researchers tended to solve the problem floods using the HEC- RAS model, as well as 23% of the researchers tended to refine the river section, while the last part of the researchers, who accounted for 10%, worked to solve the navigation problem by increasing the depth, and the most used model was obtained by the researchers, which is HEC- RAS, and reached. The percentage of researchers who used the model is 93%.
