Abstract

Spur dike (Epi) is one of the common method of bank erosion controls and river welfare. Spur dike construction changes the direction of river flow so that prevents the erosion of river bank.Affirmative and good function of this structure is related to natural properties of the river and from the other hand is based on following the technical views during the construction of spur dikes. In this study to evaluating the function of three kinds of spur dikes (gabions, SHORING, REVETMENT AND CONCRETE) constructed on MINAB river, following parameters were investigated:1-Ratio of spur dikes distances and their lenghts S/L.2- Ratio of river wides narrowing B1/B2.3- Rate of land refinding at the back of the different kinds of spur dikes through measuring the land areas.4- Rate of scour around the spur crest.5- The angle between the spur dikes and river banks and the water flow direction.6- Bed material kinds and their magnitude.7- Measuring the spur dikes dimensions.8- Depth of the spur dikes foundations in river banks.9- Kinds of construction materials used in different kinds of spur dikes.10- Date of spur dikes construction (epi ages).11- Economic Evaluation of each kinds of spur dikes.The results of an investigation shown, the best results to redirecting the flow of water has been occured by GABION constructions with angles between 100 to 120 degrees relative to up of river banks and more than 120 degree in the SHORING spur dikes. The flow of water causes meander loops between spur dikes in the S/L>3 (Ratio of spur dikes distances and their lengths). Finally according to measuring and observation and compare with formulas and studies that has been done inside and outside of the country can be results the GABION spur dikes are the best kind of spur dikes to protect of bank erosion and land refinding in the same conditions.
