A series of water-inflow tests and water electrical conductivity analyses were carried out in an area of the foundation of an arch dam. Detailed three-dimensional (3D) numerical models developed for the analyses of the test data in two foundation areas are presented. Results of rock mass permeability tests and areas where seepage paths cross each drain, identified with both water-inflow tests and water electrical conductivity analyses, were taken into account. Models were validated against flow rates and water pressures recorded in situ. By examining water-inflow tests using numerical models, the main flow processes are identified and quantified. Test results and conclusions drawn from the detailed 3D models were used to elaborate a global model of the foundation. The present study shows that borehole water-inflow tests add valuable information to the usual monitoring data, which improves our ability to analyse the behaviour of concrete dam foundations. It is also concluded that although discontinuum models provide a more natural representation of flow in jointed rock masses, equivalent continuum models can still be used successfully to study both global and local hydraulic behaviour of dam foundations.<\/jats:p>","DOI":"10.1139\/t10-052","type":"journal-article","created":{"date-parts":[[2010,12,17]],"date-time":"2010-12-17T19:07:57Z","timestamp":1292612877000},"page":"72-88","source":"Crossref","is-referenced-by-count":10,"title":["Numerical modelling of borehole water-inflow tests in the foundation of the Alqueva arch dam"],"prefix":"10.1139","volume":"48","author":[{"given":"M.
