Establishing the role of pedogenesis in changing soil hydraulic properties
Authors:S. M. Brooks  K. S. Richards
Abstract:Chronosequences provide suitable sources for the study of changes in soil hydraulic behaviour as a result of long-term pedogenesis. For a podsol chronosequence in the Scottish Highlands, data are presented to indicate the changes that have occurred over 13000 years in the saturated hydraulic conductivity (Ksat) in each horizon. As the soil profile has evolved into a differentiated sequence of three horizons, the resulting hydrological changes can be both measured and quantified by relating Ksat to textural properties and bulk density. The results are significant for interpretation of changing runoff processes and slope stability.
Keywords:Chronosequences  Saturated hydraulic conductivity (Ksat)  Pedogenesis
