ENVIRONMENTAL CHARACTERISTICS OF TUNNELS IN SOUTH VIETNAM,

Abstract

The purpose of the study was to gather quantitative measurements of various environmental factors in and around tunnel complexes, for guidance in establishing the suitability or the sensitivity requirements of various experimental or hypothetical sensor systems. The report consists mostly of a straightforward compilation of the collected data, with descriptions of the instruments and procedures employed, and an analysis of their failures. Except for directing attention to certain points which may be of interest to those engaged in sensor development, there is but minimal attempt here at interpretation of the data in terms of sensor requirements. The data were collected during March and early April 1967, which is about the latter part of the dry season for the area studied. The factors measured and for which data are included in this report are: (a) tunnel geometry, (b) surface composition, (c) microclimate, (d) vegetation, and (e) visual appearance and reflectivity.
