RESPONSE OF THE KARST PHREATIC ZONE TO FLOOD EVENTS IN A MAJOR RIVER (BOHEMIAN KARST, CZECH REPUBLIC) AND ITS IMPLICATION FOR CAVE GENESIS

Popis výsledku v původním jazyce

Hydraulic and hydrochemical relationships between a medium gradient river and a karst aquifer were studied by water level and temperature logging combined with water geochemistry and delta C-13. The cave lakes are separated from the river by a floodplainup to 150 m wide formed by a gravel and sand layer up to 13 m thick covered with fine-grained floodplain sediments. During minor discharge peaks (water level in the river < 1.5 m above the normal river stage), a water level oscillation in the cave lakessituated 40 to 190 m away from river is induced by the river level oscillation, but the river water does not enter any of the lakes. The groundwater chemistry in the cave lakes differs from that of the river water. Low bicarbonate content and high deltaC-13 values indicate that some of cave lakes' waters have undergone CO2 degassing and calcite precipitation. During a major flood (recurrence interval > 100 years, level rising 7 m above the normal stage), the river water rapidly flooded
