Abstract: A system of mathematical and graphical procedures gives solution for the steady-flow discharge and travel time for nonuniform confined ground-water conduits in which any or all of the following characteristics vary from point to point: permeability, porosity, and cross-sectional area. The methods use solutions of mathematical models based on the Darcy equation and the equation of continuity. Modified procedures give relatively simple solutions with some loss in accuracy.
