Modification of Darcy’s law for sea bed sand

Abstract

A soil consists of different size of particles and it has different permeability characteristics theoretical equation based on Darcy's law are often used to determine the coefficient of permeability in layered soil. Moreover, there is a very limited body of literature available on the validity of Darcy's law. This paper study the rate of permeability, when water contains salt flows in oceanic sand. In this paper, we examine the effect of porosity and size of sand on coefficient of permeability. Also, we study the effect of salt concentration and permeability on shear strength of sea sand.
