- Modelling deep-seated slope failures in semi-arid southern Spain Irasema Alcántara Ayala Ciencias de la Tierra deep semi arid hydrology southern Spain The aim of this research was to investigate the possible scenarios of occurrence of deep-seated failures under semi-aridMediterranean and mountainous conditions, triggered by water-table shifts caused by changes in the precipitation regimen in anarea of Andalucía, Spain. The methodology involved the combination of three different models calibrated with field data. Themodels were applied in a cascade analysis. The input of the soil water budget model was provided by rainfall, supplying the upperboundary for the seepage model, which was then used for conventional slope stability analysis. Modelling results indicated thatlarge water-table and pressure head fluctuations would occur and affect slope stability when percolation rates reach 20% of themean rainfall value. These conditions could be the result of the presence of extreme events, a change in the climate regime or theremoval of the vegetation cover. 1999 artículo científico 0016-7169 https://www.redalyc.org/articulo.oa?id=56838106 en http://www.redalyc.org/revista.oa?id=568 Geofísica Internacional application/pdf Universidad Nacional Autónoma de México Geofísica Internacional (México) Num.1 Vol.38
