Abstract : The report summarizes the field investigations conducted at 12 selected airfields located in the United States. For the purpose of obtaining the most information possible during the year, the fields chosen were divided into two groups: survey sites and comprehensive sites. In each of these groups, investigations were conducted at sites where combination drains were installed, and where subsurface drains were installed. At the survey sites, an inspection of the fields was made to determine the condition, operation, maintenance and effectiveness of the drainage system. At comprehensive sites; the operation of the subsurface drains was investigated in a systematic manner, measuring the discharge of the drains at selected locations, gaging the precipitation and observing the ground water conditions by means of observation wells; and the operation of combination drains was investigated by measuring the discharge of selected drains and obtaining precise records of precipitation for every storm.
