Influencia de la presión del aire en el goteo de una estalactita. Caso de la Cueva del Agua (Iznalloz, Granada)

Abstract

The time series analysis of a drip rate and electric conductivity of a stalactite in Cueva del Agua (Granada) during five hydrological years, has allowed to characterize several themes of the vadose infiltration. The increase of air pressure variations is one of the main factors of drip rate non-linearity (cave air pressure oscillation of 10 ± 3.7 mbar induce a drip rate variation of 0.5 ± 0.2 mm/h). This air pressure increase provoke a rise of air phase thickness inside drip to the detriment of the water phase, decreasing so the stalactite drip rate
