6. Numerical solution of soil hydraulics problems

Since the early 1970s, methods for numerically solving the differential equations that govern a large number of fundamental physical and mechanical phenomena have undergone spectacular development, linked to the growth in computer performance. The equations describing water flow in soils are among those that lend themselves well to numerical resolution. The most frequently used numerical method is the finite element method [7] 6.1 . The finite difference method [8] is also used to solve certain...
