Определение абсолютного возраста оврагов Предгорного Крыма по средней скорости отступания крутых склонов

Аннотация

The introduced method is based on the notion of parallel retreat of steep slopes of young ravins. The retreat rate is measured using dendrochronology and assumed constant during the whole time interval of the gully development. In Order to define the gully's age a hypsometric cross-profile is plotted (crossing the broadest part of the gully), the slopes steepness and distance between the slopes upper edges being marked. The values are included into age calculating formula together with the denudation rate. The method has been checked for 6 Holocene gullies dissecting Upper Cretaceous marls and Pleistocene loams at the Crimean Inner celesta ridge. The values obtained are in good agreement with age interval defined (in some cases) by archeological data.
