- Hydraulic conductivity in layered saturated soils assessed through a novel physical model Eduardo Dulcey-Leal Fausto Molina Gómez Lenin Alexander Bulla-Cruz Ingeniería test seepage statistical analysis Equivalent permeability coefficient This paper introduces a novel physical model for measuring the hydraulic conductivity of granular materials in saturated conditions. An innovation in the location of the device’s piezometers allows the device to be used to assess the permeability of layered soils for both parallel and perpendicular flows. The model’s square section construction makes soil compaction easy. Design methodology took issues of construction, calibration and implementation into account. Permeability coefficients in directions parallel and perpendicular to soil stratification were measured, and Student’s t-test was performed for the relation of experimental results and existing numerical correlations. Analysis of the results shows that the physical model can replicate seepage in layered soils with parallel and perpendicular flows as occurs in field. Furthermore, it was found that it is possible to validate the experimental calibration data by use of statistical techniques. 2018 artículo científico 0012-7353 https://www.redalyc.org/articulo.oa?id=49657889015 https://www.redalyc.org/journal/496/49657889015/ https://www.redalyc.org/journal/496/49657889015/html/ https://www.redalyc.org/journal/496/49657889015/49657889015.epub https://www.redalyc.org/journal/496/49657889015/movil 10.15446/dyna.v85n205.64473 en http://www.redalyc.org/revista.oa?id=496 Dyna application/pdf Universidad Nacional de Colombia Dyna (Colombia) Num.205 Vol.85
