Field measurements of infiltration rates are frequently used to index environmental conditions, soil hydrology, and the potential for rainstorm response. However, the variety of methods and initial site moisture conditions leads to inconsistent, confusing, and noncomparable results. Here, the relationships between steady-state infiltration velocities as measured by traditional double-ring and rainfall simulation devices are presented, along with the influence of antecedent plot moisture. The data are taken from independent efforts, mostly in semi-arid environments. Results are encouraging, and suggest that these relationships may be common to the conditions experienced, and might be used to transfer results between measurements devices and conditions.
