POSITION OF PERMAFROST BENEATH SMALL WATERCOURSES,

Abstract

Taking into account the contradictory nature of existing points of view and the conclusions drawn concerning the position of permafrost beneath small watercourses, in the region of layout of the Izvestkovaya-Urga-Chegdomyn line (southern zone of dissemination of permafrost in the Far East) a study was made of 50 small watercourses, both permanent and ephemeral, as well as runoff zones and water-intake canals. Data for more than 150 stations were considered. Computation formulas are proposed for determining the maximum depth of the upper permafrost boundary in places where watercourses flow. (Author)
