GONZALEZ, Michael Álvarez; GIL, Lamberto Álvarez  and  RODRIGUEZ, Romel Vázquez. Risk assessment and modeling of technical solutions for filtrations earth dams. Enfoque UTE [online]. 2017, vol.8, n.5, pp.26-36. ISSN 1390-6542.

The paper presents the evaluation and the analysis of three types of filter geometry to evaluate the filtration risk in Zaza Reservoir, taking as starting point the historic characteristics of the fluctuation of water levels inside the earth dam. The work is based on the experience of a multidisciplinary team and previous research with bi-dimensional models, using the Finite Elements Method for the solution of basic engineering problems. Also, the results of the installation of a new filter system with a geospatial index are evaluated (under criteria of threats, vulnerability, and risk) with spatial visualization data in a Geographical Information System for thematic maps generation, that represent how much the water level varies inside the dam according to the different filters evaluated.

Keywords : earth dam; finite element method; risk analysis; geographic information system; geospatial index..
