| description | Channel retreat are an important process in the river's morphodynamics, which affects channel variation, flood plain development and habitat development. Structures and farmland the border of the Lavij River Faces the risks of river bed change every year. Therefore, there is a need for a reliable method to determine the river bank retreat and predict the river bank Stability. In this study, with the aim of investigation of the risk of erosion and identification of areas susceptible to erosion in the Lavij River, Using BEHI and NBS models, the risk of side erosion was determined in 7 sections of this river. The results of the NBS model using the tnb / tbkf index showed that the rate of erosion of the Lavij river bank in all studied cross sections, except for cross sections 2 and 6 ,erosion rate is high and very hight. According to the indicator (dnb / dbkf), the bank erosion rate of the Lavij River, except for sections 4 and 5, is approximately consistent with the erosion trend obtained from the first index (tnb / tbkf). According the BEHI model, cross sections 5, 4, 3, 1 and 6 show a high incidence of instability and have a great potential for bank erosion and sediment production. Also, cross section 2 shows the medium instability status. Cross Section 7 and 2 show a high degree of instability, which has a high potential for bank erosion and sediment production. Finally, Kruskal-Wallis statistical test was fitted to evaluate the results matching and the results showed that all three indicators were almost identical to each other in the assessment of bank erosion. |
