The water-absorption behavior of cement pastes (w/c=0.30) containing varying concentrations (i.e., 0, 0.2, and 5%) of a shrinkage-reducing admixture (SRA) was measured. Moisture ingress was monitored using X-ray absorption. A decrease in both the depth of ...
The paper presents the results of a comprehensive experimental programme aimed to characterize the retention properties of a compacted scaly clay by determining the retention curves in terms of main wetting and main drying branches at different values of v ...
The main goal of the 3rd Rhône Correction project in Switzerland is to improve the flood protection in the Upper Rhone River basin. In this framework, the MINERVE project contributes to the flow control during flood events by preventive turbine and bottom ...
This paper deals with the definition and determination methods of the soil-water retention surface (SWRS), which is the tool used to present the hydromechanical behaviour of soils to highlight both the effect of suction on the change in water and total vol ...
A recent method based on a specific power-law relationship between the matric potential head and the Boltzmann variable was presented by Prevedello et. al. (2008). Here, this relationship was generalized to a range of powers, and the solution extended to i ...
We present the first testate amoeba-based palaeohydrological reconstruction from the Swiss Alps, and the first depth to the water table (DWT) calibration data-set for this region. Compared to existing models, our new calibration data set performs well (RMS ...
The water content dynamics in the upper soil surface during evaporation is a key element in land–atmosphere exchanges. Previous experimental studies have suggested that the soil water content increases at the depth of 5 to 15 cm below the soil surface duri ...
In this paper, we consider the problem of monitoring soil moisture evolution using a wireless network of in situ sensors. Continuously sampling moisture levels with these sensors incurs high-maintenance and energy consumption costs, which are particularly ...
Shallow landslides in Alpine regions frequently occur during heavy precipitation events or extremely fast snow melting processes. Early-warning is mostly based on simple empirical rainfall intensity and duration curves indicating probable critical climatic ...
Nitrogen (N) from atmospheric deposition has been shown to be mainly retained in the organic soil layers of temperate forest ecosystems, but the mechanisms and the physico-chemical fractions involved are still poorly defined. We performed a hot-acid hydrol ...
