Ingeniería Naturalística para prevención de riesgos en dos taludes del sur de Quito

(Received: 2013/11/01 - Accepted: 2013/12/12) Naturalistic engineering is a technical-scientific modern science cobining civil, environmental and geotechnical engineerings. It studies and uses building materials, plants, organic and synthetic materials for holding slopes. San Luis de Chillogallo and El Recreo are located in the South of Quito, where two projects for erosion control, containment and environmental recovery, have been implemented. These are pilot interventions that allow applying strategies and capabilities of estimation and reduction of risks from disasters. To implement the works, the ground was shifted, the organic and inorganic matter was wiped out, and unstable parts of the slope were removed, reshaping the slope through land exclusion and relocation. Subsequently, depending on the shape of each slope, specific techniques where designed and implemented. Double Wall Crib and Latin Triangular Branching techniques were used in San Luis de Chillogallo. Live Grating and Latino Triangular Branching techniques were used in El Recreo. Plants such as: Alder, Alnus glutinosa; paper tree, Polylepis sp.; chilca, Baccharis latifolia; lechero Euphorbia lactiflua and Tilo, Tilia platyphyllos; have been used in these projects. These plants are fast growing species and they have adapted successfully on the two slopes intervened.
