...grid, where connectivity is defined as the minimum amount of cross-sectional area along a continuous path. The upper boundary of the cross-sectional area is a fixed elevation, and the lower boundary is a gridded surface of variable elevation. My variable elevation surface represents the top of an impermeable geologic layer. I would like to represent the degree to which a fluid could flow from one end of my grid to another, above the surface and below the fixed level. I don't need to derive information about path lengths and hydraulic gradient, but if I could, that would be a plus. A groundw...
