Associated with the analysis of the effective rainfall (groundwater recharge) in this site and the flow in the cave, the Electrical Resistivity Tomography monitoring using a pole-dipole array has identified a zone which probably stores water in relation with the cave.

It is in accordance with regard to the administrative instructions, which privilege the maximal conservation to secure the integrity of art discovered recently in this extraordinary prehistorical sanctuary. This determination connected with technical statements of archaeologists, help us to understand that many red hand paintings drawn with the palm of the right hand of a man and of a woman or adolescent, were made from one unique paint pot and the mode of retouch of black charcoal drawings.

By choosing different models (one-dimensional, three-dimensional, etc.), it was possible to calculate the required variables (temperature, moisture levels, speeds, etc.) at all points inside the cave, to locate zones of high water vapour concentration and to understand the nature of the airflow. The simulations described here provide the first general data on the airflow within the cave and its hygrothermic behaviour. The temperature fields result from natural convection phenomena, which are influenced by the climate outside the cave. From the point of view of air dynamics, we can observe the presence of an overall airflow that starts in the Machine Room (containing the air conditioning system installed in 1958), runs along the ground to the end of each of the branches of the cave, and returns along the cave vault to its starting point. This slow-moving phenomenon suggests the possibility of passive control of the ambient air from the Machine Room. There are localized risk areas where condensation of water vapour can occur, resulting in rapid deterioration of the limestone. Several of these areas are therefore monitored using condensation indicators placed on the cave walls or by visual observation of painted areas. The higher air speeds detected in some areas of the cave result in decay of the prehistoric paintings. The numerical modelling results, confirmed by observations and measurements in situ, should be taken into consideration when managing the conditions within the cave.

Investigation of groundwater behavior in response to oceanic tide and hydrodynamic assessment of coastal aquifers

Recordings were made in the well located at 1318 m from the coast, where the two aquifers are in direct contact. This investigation was subdivided into two periods of 4 months each. Results showed a tidal influence on water table level within the well during semi-diurnal and monthly periods. Water table fluctuation periods were equal to 12 h 25 min identical to oceanic tide propagation period, while time lag between water levels was equal to 3 h 24 min. Moreover, results allowed aquifer diffusivity calculation through a confined aquifer model, which was equal to 6.20 m(2) s(-1) calculated from average value of water amplitude and to 40.6 m(2) s(-1) calculated from average value of time lag. In addition, tidal wave amplitude attenuation occurred exponentially with distance from ocean, which disappeared completely after 2000 m from coast.
