Khaksar Najafi, A. Eslami] Suffusion is a process of soil particle transfer in the soil body due to the effect of seepage flow on it. Although up to now internal instability has been considered in hydraulic structures such as dikes, dams and canals, todays, occurring of this phenomenon in arid regions and non-hydraulic constructions was seen. Shahriyar County in Iran, located on alluvial soil deposits, is an area where the non-hydraulic structures built there have been damaged by erosion. Even though there is no surface water flow, a seepage force has been generated by water leakage from buried pipes and sewage disposal wells. In this article, we tried to determine whether suffusion occurs in Shahriyar. Because of the limited number of available methods for the assessment of suffusion, in this article, a new approach is presented using statistical analysis to assess the internal instability of alluvial soils. This approach was developed and verified using a relatively large database of unstable soils. The performance of the presented approach was compared with those of three commonly used methods. It is showed this approach can predict the likelihood of internal instability with a relatively high accuracy rate.
