SUBSURFACE DRAINAGE INVESTIGATION 1946 - 1947. (DRAFT). COMPREHENSIVE REPORT.
Abstract
The basic purpose of the subsurface drainage investigation is to establish design criteria for inclusion in the Engineering Manual, with the secondary purpose of investigating the effectiveness of drainage systems at several existing airfields. The study includes the investigation of both combination and subsurface drains. The investigation of combination drains consists of obtaining rainfall and runoff records at test areas on three selected airfields. The investigation of subsurface drains to date has consisted of observing the operation of subsurface drainage installations of six airfields, by means of observation wells and drain discharge measurements. The data obtained at these field sites are presented in this report. A theoretical analysis of base course drainage was made during the fiscal year 1945 - 1946. This analysis was supplemented by viscous fluid model tests and full scale field drainage tests were conducted to verify theoretical formulas. (Author)
