The U.S. Geological Survey computer program TENSOR2D may be used to compute the directional components of the anisotropic transmissivity tensor of two‐dimensional ground‐water flow. In this note, modifications to the original computer code, developed in 1987, are described. Because of the modifications, TENSOR2D now conforms to the Fortran 77 Standard and can be run on most personal computers without user modification. Additionally, a new routine generates the polar coordinates of the computed theoretical transmissivity (or diffusivity) ellipse.
