The porosity of saturated shallow sediments from seismic compressional and shear wave velocities

► I devise a new analytical relationship to determine the porosity of water-saturated soils using shear modulus and Poisson's ratio calculated from seismic velocities. ► This relationship indicates that when the shear modulus of water-saturated loose soil increases, porosity decreases logarithmically. ► If shear modulus increases in dense or solid saturated soils, porosity decreases linearly.
