dc.description.abstractA groundwater flow model in La Aldea ravine lower part (Gran Canaria) has been developed. The zone has been tridimensionally discretized as cells of 50 x 50 m considering 3 layers. The superficial layer is formed by sedimentary and volcanic materials (Alluvial, screes and altered basalts) and the intermediate and lower layers are basalts. The model has been developed in stationary state for the average hydrologic year 1991/92 and in transitory state for the period of 1991/92-1998/99. The North, South and East limits have been defined as null flow boundary conditions, the coast line has been defined as constant level and the ravine bed at the east has been defined as a constant flow, representing the contribution from the upper ravine basin. Recharge is a result of rainfall, irrigation returns, supply network leaks and inflow from the intra-caldera zone. Discharge takes place by pumping wells and flows towards the sea. The bottom surface is defined as a null flow condition in the limit between altered and unaltered basalts. A drain condition has been imposed in the ravine and the pumping wells extraction has been located. The simulation results indicate that the transmisivities obtained in previous works present the same order of magnitude than the obtained in the model and the calculated levels are in good agreement with the observed levels measurements.en_US
