Water chemistry and chemical denudation in relation to local
environmental conditions were investigated in a drainage basin of
approximately 9 km(2) in northernmost Swedish Lapland (Latnjavagge).
Discharge and surface water electric conductivity were measured over the
summer of 2001 at selected sites. The chemical investigations show
differences between sub-areas and changes over the season as well as
overall rates of chemical denudation. Transects within the catchment
using a radio-magnetotelluric geophysical method describe regolith
thickness and ground frost conditions at the time of measurement. This
combination of methods obtains information on the influence of regolith
thickness and ground frost upon sub-surface drainage and chemical
denudation, not only along the profiles but also, by extension, on areas
further upslope. In this paper the techniques are outlined and the
approach demonstrated for three sub-areas with different regolith
thicknesses and thaw development. Copyright (C) 2003 John Wiley Sons,
