Abstract

A mountainous karst landscape characterised by very steep slopes and predominantly underground
drainage has evolved in the tropical mountains of northwest Thailand. The underground drainage
routes havc been left hanging above the floor of the the Nam Khong valley, which has been out in noncarbonate
sediments that underlie the folded limestone. Gravel deposits are widespread along the streams
and relict diamictons cloak many hillsides. Deposition of these sediments has occurred since the middle
Pleistoccne. Slash and burn agricultural practices have generated only fine sediment from steep hillslopes
during thc late Holocene despite localised annual stripping of all the vegetation cover immediately preceeding
the most intense monsoon rains. Gulleys cut into the diamictons indicate changes in the sediment
load and moisture discharge ratio during the late Holocene that may be associated with increassed human
population pressures in the area.
