Abstract

Three parameters derived from air photo interpretations namely: lithology, lineament index and drainage index have been employed to compute a ground-water site evaluation index (GWSEI).

The GWSEI values are then used as a basis to evaluate the groundwater potentials of borehole sites.

Results from the study show that high GWSEI values are consistet with high borehole yield values.

Évaluation de sites de pompage à l'aide de la photo-interprétation

Résumé

Trois paramètres sont définis à partir de l'interprétation des photographies aériennes: la lithologie, les linéaments, le drainage, caractérisés par des «indices».

Ces derniers servent de base à une évaluation des nappes souterraines (indice GWSEI: «ground-water site evaluation index»).

Les valeurs de cet indice permettent d'estimer les potentialités des sites de pompage.

L'étude montre que les valeurs élevées du «GWSEI» correspondent effectivement à des débits élevés sur les sites.
