Document Summary
K as a function of position, direction and degree of saturation. As well as being a function of the fluid, hydraulic conductivity, k, also varies with position, direction and degree of saturation. Directional variability: changing according to direction: isotropy and anisotropy, we also find that many rocks exhibit different values of k in different directions. In systems, comprising of several isotropic layers, it is often convenient to combine the data to obtain one representative value for an equivalent isotropic system. I want to know what the overall effect of k is to give a representative value of flow. Parallel to the layers (di is thickness, d is total thickness). =1 - for where we have layers with different values of k for each layer, and. =1 represents flow normal to layers, this calculation helps us find k. Perpendicular to layers: z means perpendicular to layers, x is parallel to layers.
