Q1. Based on the conventional analysis on the water flow in soil, it is usually assumed there is no water flow in unsaturated soil. Please discuss whether this assumption is valid, and explain the associated reasons. Q2. Discuss the soil classification w.r.t. 1) direction (i.e., orientation) and 2) spatial position. Q3. Please discuss 1) the physical meaning of the two components of flow equation for the 3D water flow in the unsaturated soil, 2) which component can be used to describe the nonlinear water flow behavior in soil, and 3) difference of nonlinear water flow behavior between saturated soils and unsaturated soils. 8²h əx² K WX +K WW 0²h +K dy² 1st component W2 WX wy d'hak dhak dhak dh + + + əx əx dy dy əz əz 2nd component dz² WZ = 0 Q4.
