Performance of Subsurface Drains at Selected Airfields During the 1960 Frost Melting Period by William C. Sayman,George D. Gilman,Cold Regions Research and Engineering Laboratory (U.S.) Pdf
During the 1960 frost melting period, the performance of subsurface drainage systems was investigated at selected airfields in the northern continental United States by periodic observations at manholes and/or risers. Records of air temperature, subsurface temperature, and precipitation were also maintained. The observations were one-time 'spot' notations, intended to determine the feasibility of performing more comprehensive studies and no quantitative measurements were undertaken; nor do the data obtained permit evaluation as to the overall effectiveness of the inspected systems or the validity of the criteria used in their design. However, the study showed that the observed subdrain systems were generally performing their function of removing subsurface water. The study also confirms the need for periodic inspection and maintenance of all subsurface systems. (Author).
