Abstract: Tenerife is the largest island of the Canarian archipel,
situated approximately 300 km west of Africa and 400 km north of the turning-point
of the cancer. Because of the influence of the passat-winds the island
is climatically subdivided into two parts. Precipitation of over 1000
mm/a are possible in the North, arid conditions prevail in the Southern
regions. Geologically and hydrogeologically the island is influenced by
a structural system from the Teide Pico Viejo complex and acting as the
main channel way for the magmas. Because of increased dike densities at
the center, this structural system also influences the hydrogeological
situation. Hydrogeologic models developed earlier show an interconnecting
aquifer system for the island. Recent studies, however, indicate a zonation
of the aquifer with clearly defined variations in permeabilities and hydraulic
storage coefficients.
During this study waterchemical analyses were performed and isotop-hydrological
profiles were established to show regional differences in aquifer behavior
and to establish recharge areas for known groundwater occurrences. It
was shown, that the groundwater in the north is recharged through overlaying
lithologies, while the south is recharged through more distant areas higher
elevations. Temperature calculations and age-determinations of the water
yielded hydraulic velocities and conductivities of the area, conforming
previous investigations of this study.
