Riesgo geológico en un valle interandino colombiano por la eventual construcción de una presa

Autor: Muñoz, V.
Otros Autores: Rodríguez, C.
Tema(s):
Resumen: In: Hermelín A., Michel, ed. Memorias. Medellín, Antioquia. Universidad EAFIT, Jul. 1992. v.1. v.1. Presentado en: Simposio Latinoamericano de Riesgo Geológico Urbano, 2; Conferencia Colombiana de Geología Ambiental, 2; Pereira, 15-18 jul. 1992. Cauca River northward between Central Cordillera and Western Cordillera of the Colombian Andes. The construction of the Cañafisto Dam has been projected in the middle valley, in the Antioquia Department Southwestern region. Once the hydroelectric dam will start working, the river will increase its erosional capacity downsteram, principally as bank degardation of the Quaternary alluvial and colluvial deposits which contain of fine particles. There are knickpoints like hard rocks or boulder and coarse grain deposits which armor the bottom of the river channel; hence, it is not likely that vertical erosion willoccur in the bed of the river. The following engineering works will be threatened: Sucre-Liborina road, Paso Real bridge, Medellín Turbo road, Los Halcones airstrip and many buildings in the Olaya town and in the San Nicolas Village (AU).
