Soil quality - Determination of unsaturated hydraulic conductivity and water-retention characteristic - Wind's evaporation method (ISO 11275:2004)

ISO 11275:2004 specifies a laboratory method for the simultaneous determination in soils of the unsaturated hydraulic conductivity and of the soil water-retention characteristic. It is applicable only to measurement of the drying or desorption curve. Application of the method is restricted to soil samples which are, as far as possible, homogeneous. The method is not applicable to soils which shrink in the range of matric head 0 cm to -800 cm.
The range of the determination of the conductivity depends on the soil type. It lies between matric heads of approximately -50 cm and -700 cm.
The range of the determination of the water-retention characteristic lies between matric heads of approximately 0 cm and -800 cm.

Bodenbeschaffenheit - Bestimmung der ungesättigten hydraulischen Leitfähigkeit und des Wasserrückhaltevermögens - Verdunstungsverfahren nach Wind (ISO 11275:2004)

Diese Internationale Norm legt ein Laborverfahren für die simultane Bestimmung der ungesättigten hydraulischen Leitfähigkeit und des Wasserrückhaltevermögens eines Bodens fest. Sie ist nur für die Ermittlung der Trocknungs- bzw. der Desorptionskurve anwendbar. Die Anwendung ist auf Bodenproben beschränkt, die so weit wie möglich homogen sind. Sie ist nicht anwendbar auf Böden, die innerhalb der folgenden Matrixhöhen schrumpfen können: hm = 0 cm bis hm = –800 cm.
Der Bestimmungsbereich der Leitfähigkeit hängt von der Bodenart ab. Er liegt zwischen Matrixhöhen von etwa hm = –50 cm bis hm = –700 cm.
Der Bestimmungsbereich des Wasserrückhaltevermögens liegt etwa zwischen hm = 0 cm bis hm = –800 cm.
ANMERKUNG 1   Zur Bestimmung der hydraulischen Leitfähigkeit nahe dem gesättigten Bereich kann ein Infiltrometerverfahren angewendet werden.
ANMERKUNG 2   ISO 11274 enthält Verfahren zur Bestimmung des Wasserrückhaltevermögens bei Matrixhöhen zwischen 0 cm bis –15 000 cm.

Qualité du sol - Détermination de la conductivité hydraulique en milieu non saturé et de la caractéristique de rétention en eau - Méthode par évaporation de Wind (ISO 11275:2004)

L'ISO 11275:2004 spécifie une méthode de laboratoire pour la détermination simultanée de la conductivité hydraulique en milieu non saturé et de la caractéristique de rétention en eau du sol. Elle est applicable uniquement au mesurage de la courbe de dessèchement ou de désorption. L'application de cette méthode est limitée à des échantillons de sol qui sont, autant que possible, homogènes. Cette méthode n'est pas applicable aux sols présentant un retrait dans la plage de charge matricielle comprise entre 0 cm et moins 800 cm.
La plage de détermination de la conductivité dépend du type de sol. Elle se situe entre des charges matricielles comprises environ entre moins 50 cm et moins 700 cm.
La plage de détermination de la caractéristique de rétention en eau se situe environ entre 0 cm et moins 800 cm.

Kakovost tal - Določanje hidravlične prevodnosti in karakteristik zadrževanja vode v nenasičenih tleh - Metoda izhlapevanja po Windu (ISO 11275:2004)

Standard EN-ISO 11275 določa laboratorijsko metodo za hkratno določanje hidravlične prevodnosti in karakteristik zadrževanja vode v nenasičenih tleh. Uporablja se samo za merjenje sušilne ali desorpcijske krivulje. Uporaba te metode je omejena na vzorce tal, ki so, kolikor je le mogoče, homogeni. Razpon določanja prevodnosti je odvisen od vrste tal.
