摘要: Investigation of the 2007 flows from Chalala and Coquena, Purmamarca, Jujuy Province. This work presents results investigation mudflows Quebrada de Coquena 7 March, 29 March same year. These stream basins are tributary to Purmamarca located in Cordillera Oriental, Province, Argentina. The studies focussed on classification type mass flow quantification magnitude these events. Flow velocity was calculated using two different equations. Both methods produced similar results. volu- me measured directly field. relationship between total discharge (V) peak (Q p ) estimated by equations for geotechnical literature.
