RESUME

S. Tweed est une chercheuse en hydrogéologie, spécialisé dans l’utilisation des traceurs environnementaux pour étudier les processus hydro(géo)logiques, avec des applications pour la protection des ressources en eaux en termes de qualité et de quantité. Ses recherches se sont déclinées sur plusieurs types d’hydrosystèmes (aquifères poreux et fracturés, rivières, lacs) dans une variété de contextes climatiques (tempéré, semi-aride, aride et tropical sec et humide) avec des enjeux portant sur la quantité et la qualité des ressources en eau. Ses recherches ont également porté sur plusieurs composantes du cycle de l'eau : recharge et décharge des aquifères, voies de circulation souterraines, et interactions entre les eaux souterraines et les eaux de surface. Depuis 1998, elle utilise l'hydrochimie comme méthode pour étudier les ressources en eau en Australie, au Sénégal, au Maroc, en France, au Cambodge et au Vietnam.
