Numerical and Field Investigation of the Impacts of the Bank Protection Projects on the Fluvial Hydrodynamics (Case Study: Ghezel Ozan River)

Abstract—River training refers to the operations which are optimally used in length or width of the river, and provides significant objectives. Achachi Village is one of the most important rural areas of the Mianeh City in Iran, and Ghezel- Ozan River runs adjacent to it and makes its lands more fertile. On the other hand, the arterial borders of the river cause a lot of damages in the area. Therefore, an embankment dike and a couple of fully-stone groynes were constructed to protect the agricultural lands; however, some parts of those structures were destroyed because of flood, and they gradually lost their efficiency. The second phase of Ghezel-Ozan River training studies is done by Water Research Institute belonging ministry of energy. Moreover, the area is modeled by HEC-RAS. The properties, such as average velocity and water depth in the river, can be evaluated by one-dimensional models. However, using two-dimensional models is vital for the modeling the vortex formation between the groynes, determination of optimum distance between them, and the application of the structures. In this study, numerical modeling of the hydraulic phenomena is computed by MIKE21-FM which is one of the most powerful software in the world. Consequently, the groynes impact on Achachi River is investigated in various cross sections, and also vortex formation and stream velocity around them are analyzed.

Index Terms—Computational fluid dynamics, finite difference, Groyne, MIKE by DHI software.
