Using synthetic models to understand the detecting ability of ground‐penetrating radar for water‐conducting structures in the bedrock of formerly glaciated site

Near Surface Geophysics, EarlyView.
Abstract Utilizing synthetic models for the interpretation of ground‐penetrating radar (GPR) profiles can aid in the detection of hydrogeological structures by identifying their signatures. In this study, finite difference (FD) forward modelling was used to understand the detection ability of 50 MHz GPR for (1) the quaternary deposit–bedrock contact ...

SATURATED HYDRAULIC CONDUCTIVITY MEASUREMENTS OF SOIL SAMPLES AT LABORATORY SCALE

, 2013
Saturated hydraulic conductivity (Ks) is one of the most important hydraulic properties affecting water flow in soils/sediments. The objective of this investigation is comparison of different methods for Ks determination. Empirical methods using grain size analysis, ROSETTA pedotransfer function model using grain size analysis and bulk density, as well

Patterns and environmental drivers of root traits across hydrological gradients in old growth boreal forests

Oikos, EarlyView.
Many key ecosystem functions are affected by plant roots and their traits. However, understanding of the patterns in, and drivers of, root traits lags far behind equivalent knowledge of above‐ground tissues, particularly in boreal old growth forests. We surveyed community‐level root traits across 11 old growth forests spanning a wide latitudinal range ...

Estimate of areal average infiltration through an equivalent saturated hydraulic conductivity

, 2000
A simple semi-empirical model for areal average infiltration at slope scale is proposed. It involves the estimate of an equivalent saturated hydraulic conductivity, Kse, which enables us to reduce infiltration into a randomly varying field of saturated ...
