“…As they spill out of the basin, they cause the dam to collapse and spill downstream, generating a mudflow that rapidly covers distances from a few to many kilometers, sometimes with considerable velocity that does not allow the population to be alerted (see Table 3). Not only is this scenario consistent with the mudflow in the Stava Valley (Chandler and Tosatti, 1995), it is also evident in the earlier disasters.…”

“…Analyses revealed that the geotechnical characteristics of the materials (Chandler and Tosatti, 1995) taken from the impoundment dams were remarkably homogeneous: the range of the shear strength angle was between 33 • and 37 • ; the cohesion was zero (the Atterberg limits were either not determinable or gave consistency indices (CI) between −0.4 the official map before the collapse. Red lines show failure and the path of the mudflow (courtesy of Fondazione Stava 1985).…”

“…As a consequence, the mining industry has recently experienced several significant dam failures, with important examples in South Africa (Blight et al 1981;Van Niekerk and Viljoen 2005); Guyana (Vick 1996); Spain (Ayala-Carcedo 2004;Gens and Alonso 2006); Romania (UNEP/OCHA 2000); Italy (Genevois and Tecca 1993;Chandler and Tosatti 1995); Chile (Dobry and Alvarez 1967); and Sweden (Holmgren 2000;Göransson et al 2001). Rico et al (2008b) documented 147 cases of dam tailings failures worldwide, triggered by 16 different factors, including management operations, seismic liquefaction, rises in the phreatic surface, slope instability, fluvial undermining, inadequate/insufficient beach or free board, piping/seepage, dam overtopping/overflowing, foundation failure, snowmelt, inadequate decant pipe construction, unusual rainfall events, insufficient efficiency of the filter drain, incorrect prediction of mine subsidence, and structural failure.…”

“…The new version of RASH 3D has then been used to simulate the well documented case of a pair of tailings dams whose failure, on 19 July 1985, generated a catastrophic flood in the area of Stava, Northern Italy (Berti et al 1988;Chandler and Tosatti 1995).…”

“…As summarized by Blight and Fourie (2003), if for any reason the dam wall breaks, there is the danger that the settled tailings can escape the impoundment, causing mass movements and/or a flow failure, which commonly results in serious socioeconomic and environmental consequences. Several dam failures have occurred during the past century, with key examples studied in South Africa (Blight et al, 1981;Van Nierkirk and Vlijoen, 2005), Spain (AyalaCarcedo, 2004;Gens and Alonso, 2006), Italy (Genevois and Tecca, 1993;Chandler and Tosatti, 1995;Berti et al, 1997), and Chile (Dobry and Alvarez, 1967). Sammarco (2004) grouped dam breakouts into two categories: (i) failures in which water flows over the tailings causing erosion and transportation of the material progressively deposited downstream (overtopping) and (ii) failures in which liquefaction of the tailings and/or breakout of the dam produces a highly hazardous flow that rushes downhill.…”
