Abstract

Schmidt-hammer exposure-age dating (SHD) was applied to 3 flood berms in upper Vetlestølsdalen, southern Norway, using a local, high-precision calibration curve that takes account of the colluvial origin of fluvial boulders in the youngest berm, which was deposited during the August 1979 flood. Precision of SHD dating for this berm was estimated as 210 years. The dated berms indicate a return period of 1000–1500 years for floods of the magnitude of the 1979 flood event in the upper catchment. Thus, the long-term persistence of flood boulder berms in the landscape has potential for reconstructing Holocene flood history and palaeohydrology from the geomorphic legacy of the most extreme Holocene floods
