We explain a procedure to analyze the flow through the network structure on the digital image. The network analysis described in this paper is as follows. First we construct the Pore-Channel (PC) model using the tessellating triangles of the network area. The tessellation procedure was previously explained in Nakano and Fujii (1991b) . For the flow percolating through the network, we calculate the resistance due to channel geometry, and construct the resistor network model. Calculating the net resistance of the network, we can obtain the macroscopic permeability and/or electiric conductivity of the network structure on the image data. We also explain the computer programs for the above procedure.
