dc.description.abstract The Zagros Mountains Range is an important structural unit in south western Iran and accommodates a significant portion of the 2.5 cm/year convergence between Arabia and Eurasia. This structural unit includes folds, thrusts, strike-slip faults and salt diapirs. There is evidence of past failures in the area, probably some 11,000 years ago. In the order of 30 million cubic metres of rock debris was moved from the Kabir Kuh Anticline as well as rock failures from the Ravandi Anticline. Investigations indicated 4.5 m of landslide/rock fall debris underlying about 28 m of lake deposits and 5.5 m of recent river alluvium upstream of the Seymareh Dam area. The direction of the Seymareh River bed was displaced by about 1,000 m to the northeast, forming a sharp river meander near the entrance to the gorge of the Ravandi Anticline where the Seymareh Dam is being constructed. The paper reports the rock slope instability modelling, kinematic analysis of slope faces and landslide hazard zoning undertaken. en_ZA
dc.description.abstract La chaîne du Zagros est une unité structurale importante du sud-ouest de l’Iran. Elle enregistre une partie importante des 2,5 cm/an de convergence entre l’Arabie et l’Eurasie. Cette unité structurale présente des plis, des chevauchements, des failles de décrochement et des diapirs de sel. Il existe des preuves de jeux de failles dans la région, il y a 11 000 ans probablement. Environ 30 millions de mètres cubes de matériaux rocheux se sont détachés de l’anticlinal de Kabir Kuh, de même que des glissements rocheux ont eu lieu à partir de l’anticlinal de Ravandi. Des reconnaissances de terrain ont montré que 4,5 m de débris issus de glissements de terrain et de chutes de blocs se trouvaient sous environ 28 m de dépôts lacustres et 5,5 m d’alluvions récentes en amont de la zone du barrage de Seymareh. Le lit de la rivière Seymareh a été déplacé d’environ 1000 m vers le nord-est, formant un méandre serré à l’entrée de la gorge de l’anticlinal de Ravandi où le barrage de Seymareh est en train d’être construit. L’article présente la modélisation des instabilités des pentes rocheuses, l’analyse des conditions de stabilité des versants et le zonage des risques de glissements de terrain. en_ZA
