"This report describes a stochastic discrete fracture (SDF) modelling package that simulates ground-water flow and mass transport in fracture systems. The program NETWRK generates two-dimensional fracture networks with a Monte Carlo method based on the statistics of field data on fracture geometry, i.e., fracture orientation, trace length, aperture, and density. The program APEGEN can be used to generate supplementary aperture distributions for the fracture network generated by NETWRK. A third program, NETFLO, computes the steady-state fluid flow through the fracture network generated by NETWRK and APEGEN. NETFLO also computes the statistic s of selected parameters in every ten-degree range of direction, including the total length of fracture segments, the total flow velocity, and the total flow rate. The latter directional parameters are used by the program NETRANS to compute the transit time of particles over an arbitrary distance using a second-level stochastic process"--Abstract, p. vi.
