Despite the high geoheritage value of caves and karsts, northern Ethiopia’s largest cave at Zeyi (13.5586°N, 39.1454°E) in the Dogu’a Tembien district has received little attention so far. We have studied its geological, geomorphic, socio-cultural and historical dimensions in a holistic way. The basal member of the Antalo Limestone, in which the Ze...
L’association française de Karstologie est présentée à travers son organisation, sa vie administrative et ses activités. Celles-ci sont essentiellement l’activité éditoriale, l’organisation de rencontres annuelles de terrain et de colloques. Après quarante années d’existence, l’association a organisé 43 excursions de terrain (dont 13 à l’étranger),...
Sur l'exemple du futur Tribunal de Grande Instance de Paris, IGH venant s'inscrire dans des terrains minés par le karst gypseux Antéludien, cette étude montre comment les paramètres de foration des sondages destructifs peuvent être un outil adapté à la définition et au dimensionnement des fondations dans un contexte de terrains présentant un compor...
During a flood event over a karst watershed, the connections between surface and ground waters appear to be complex ones. The karst may attenuate surface floods by absorbing water or contribute to the surface flood by direct contribution of karst waters in the rivers (perennial and overflowing springs) and by diffuse resurgence along the hillslopes...

It is proposed to construct a dam across the Geba River, Ethiopia. The paper reports the engineering geological investigations undertaken, including mapping, discontinuity surveys, core drilling, water absorption testing and sampling for laboratory tests. The complexity of the site, with limestones and interbedded limestone-shale horizons, is indic...
