DIFFERENTIATION OF SEDIMENTS IN THE SUCHEDNIÓW WATER RESERVOIR (ŚWIĘTOKRZYSKIE VOIVODESHIP, POLAND)

Abstract

The Suchedniów water reservoir was built in 1974 in the middle section of Kamionka river (Świętokrzyskie voivodeship in Poland) in the area of earlier industrial water reservoirs existing here during the Old Polish Industrial District time. Research carried out after drainage of this reservoir in 2017 showed that the pond has preserved forms and sediments documenting contemporary anthropogenic activity (fireproof clay layer, inland fan delta), historical marks (lacustrine sediments of older reservoirs), as well as traces of catastrophic event (sandy mega ripple marks formed after suddenly drainage caused by dam breaking in 1974). Field and laboratory analysis allowed to gather information on the grain size differentiation of sediments in the reservoir area.
