“…Pore wa ter pres sure val ues mea sured in the soil just be hind the cone tip can be dis tin guished from the pore wa ter pres sure in hy drostatic stress con di tions. An ex pla na tion of this ef fect can be given fol low ing Van Baars and Van de Graaf (2007). In a piezocone test, the sur round ing soil is com pressed by the pene tra tion of the cone tip, which cre ates ex cess pore wa ter pressure.…”

As so ci ate Ed i tor: Szymon Uoecinowicz This study iden ti fies zones with sig nif i cant changes in pore wa ter pres sure in flu enced by land slide pro cesses. Mea surements were taken in the near-sur face strata of the Carpathian flysch, in col lu vium of the Siercza land slide, near Kraków. Mea sure ment of pore wa ter pres sure in flysch de pos its is com pli cated due to the strongly heterogeneous prop er ties of the me dium and by vari able wa ter con di tions, which are strongly in flu enced by rain fall in ten sity. Pore pres sure pro fil ing was performed in six se ries us ing a cone pen e tra tion test with a NOVA Acous tic cone. The tests were car ried out in the col lu vium to a depth of ~6.0 m un der vary ing wa ter con di tions. The cone pore pres sure re sults were com pared to re sults of in cli nom e ter mea sure ments in the re search area. Five zones with sig nif i cant dif fer ences in pore pres sure have been iden ti fied. Changes in both cone pore pres sure and in cli nom e ter dis place ment are ev i dent at a depth range from 1.5 to 2.5 m. Two slip sur faces are likely pres ent in this sec tion. Such in for ma tion can be used in en gi neer ing prac tice for more re li able as sess ment of slope sta bil ity in the Carpathian flysch.

“…Hydraulic permeability Can only be estimated with a CPTu, for a saturated medium, thanks to the interstitial pressure values. Van Baars and Van De Graaf [2007] propose the estimation of compressible soils' hydraulic permeability using a piezocone. Robertson and Cabal [2010] propose a permeability estimation using the Soil Behaviour Type (SBT).…”
