GARCIA F., Willman; DELFIN S., Mirko; LEDEZMA P., Mauricio  y  AREVALO S., Boris. Integrating methods for assessing the risks of landslides and floods in the Tunari basins and the Alto Cochabamba area. RevActaNova. [online]. 2021, vol.10, n.1, pp.61-95. ISSN 1683-0789.

The study emphasized a risk assessment in two pilot basins in the Tunari mountain range (K'hora in Tiquipaya and Kaquerama in Sacaba) and in the Alto Cochabamba area. Three comprehensive methods were used: i) Participatory evaluation (qualitative and quantitative) of risk, ii) Mapping of landslide vulnerabilities with GIS and iii) Run of two-dimensional hydrological and hydrodynamic models for flood simulation. There is a high degree of risk of forest fires and mazamorras; medium risk of floods and landslides, with highly exposed vulnerable elements (urbanizations) in the streams of both basins and in the Alto Cochabamba area. There is evidence of a lack of maintenance of structural works to reduce risks and very low implementation of new works. The simulations show that there is a wide range of flooding mainly in the middle and lower part of the basin affecting established populations, basic services and livelihoods in general.
