Abstract
The aim of this research is to study of the hydraulics and evaluate the performance of spurs which are built to protect the Felman wells and to prevent the further destruction of the protected area in the Shoteyt River bank and near the city of Shoushtar (Iran) by MIKE11 model. Since in the area under study the Shoteyt River bank is seriously at the risk of scour, the hydraulic study of constructed spurs is utmost important in order to the effectiveness of them. In the present study, the flow’s condition is assumed to be unsteady and the results indicate the efficiency of the spur as well as suitability of the model in simulation of spurs. The results achieved by this software in the studied area show changes in water level and flow rate. Construction of spurs can reduce the flow rate by115 m3/s over a span of 100 year. The maximum change in water level for this flood has been 47 cm, and the maximum change in flow rate has been 0.558 meters per second. Comparing the results of a flood with a return period of 25 years and a spate with a return period of 100 years, it was noticed that these changes have a direct relation with the increase of return period and the more return period of flood increase, the more changes take place.
