Figure Q1.d) below shows particle size distributions for Soil A and Soil B. Figure Q1.d): Particle size distribution for Soil A (red circles) and Soil B (blue triangles). i) For Soil A only: Estimate the hydraulic conductivity given that the porosity is 22%. (Density of water: =1000kgm3, acceleration of gravity: g=9.8ms2 ) [4 marks] ii) For Soil B only: According to standard soil size classification, how much of each particle type does Soil B consist of? [2 marks] iii) Based on the soil size distributions, give a brief assessment of Soil A and Soil B in terms of their properties as aquifer materials
