Optimization the permeability coefficient of the soil at different locations in the Akkar Plain using statistical program (Ms-statistical).

Abstract

The Akkar Plain, located south of Tartus, is a plain with sandy soil in some west parts near the sea. Soil permeability is a crucial factor in studying water flow, and permeability coefficients vary across different areas of the Akkar Plain. Therefore, this research aimed to find an empirical equation to calculate the permeability coefficient for any area of ​​this area. In order to simulate this variation in the plain's soils, several samples were collected from randomly selected locations in these areas of the plain, at varying depths. A general empirical equation was found to calculate the permeability coefficient for soils in this area in terms of the uniformity coefficient (Cu), effective diameter (D10), and void ratio (e), using a statistical program and depending on results of permeability coefficient values ​​obtained from the laboratory for samples brought from different areas. This extracted equation was compared with the theoretical equation derived by Boisley, and it was found that the equation we obtained gives results close to the theoretical equation derived based on assumptions, with a slight difference due to the different experimental conditions than those assumed in the theoretical derivation.
