Web5 m/s whereas the infiltration test (Porchet method) results vary from 1.91 x 10-7 m/s to 1.16 x 10-6 m/s. The simulated hydraulic conductivity values range from 2.54 x 10-7 m/s to 6.36 x 10-7 m/s, with a decreasing trend in the northeast-southwest (NE-SW) direction. Research Article WebOne way to numerically solve this equation is to approximate all the derivatives by finite differences. We partition the domain in space using a mesh , …, and in time using a mesh , …,.We assume a uniform partition both in space and in time, so the difference between two consecutive space points will be h and between two consecutive time points will be k.
