Sistema de classificação dos solos baseado na estrutura do espaço poroso
… pore space structure and takes into account the water retention curve. SPSCS was designed according to the textural classification system and it conceives a structural triangle equivalent to the textural triangle. Nine Orders and four Suborders were proposed, resulting in 36 structural Families …

Estimating scale dependence of saturated hydraulic conductivity in soils
… the K_sat at the large scale from the soil water retention curve and K_sat measured at the small scale. We find the root mean square log-transformed error (RMSLE) values 0.45, 0.77, 1.9, and 2.05 (cm/day) for sites Jyndevad, Tylstrup, Silstrup, and Estrup, respectively. Results show that the …

Étude des recouvrements avec effet de barrière capillaire pour minimiser les infiltrations d'eau dans les sites d'enfouissement de matières résiduelles
… an efficient control to the infiltration of water into the landfill, thereby reducing the amount of leachate produced. Given its water retention characteristics, DBP can also help to control biogas emissions. An experimental cell at Saint-Tite-des-Caps landfill, Québec, was designed to be a …

Quantification of wildfire-induced perturbations to soil-water retention curves and their impact on rainfall runoff
… rates into unsaturated soils. The soil-water retention curve (SWRC), also called the soil-water characteristic curve, is the relationship between matric suction and soil-water content and determines many critical unsaturated soil properties such as unsaturated hydraulic conductivity. The …

Development and Use of Moisture-Suction Relationships for Geosynthetic Clay Liners
… tests, and relative humidity tests, then fitting water retention curves (WRCs) to the data. WRCs were determined for wetting processes and drying processes in terms of gravimetric moisture content and volumetric moisture content.</p> <p>The effects of GCL type, hydration solution, wet-dry cycles, …

Measurement of Soil and Water-Quality Parameters to Understand Subsurface Transport Processes
… as excess rainfall and/or draught cycles on saltwater intrusion processes with a focus on managing freshwater resources in island aquifers. As part of this effort, we used a combination of laboratory experiments and numerical simulations to study the impacts of changes in rainfall patterns on …

Moisture transport and fixation in porous materials at high moisture levels
… were calculated from the relation between the water sorption coefficients and the initial water content. The method is based on Boltzmann transformation. Knowledge of moisture storage capacity over the hygroscopic range is essential when calculating the moisture content. Generally storage …

Experimental and numerical analysis of behaviour of the myxospermous seeds of Capsella bursa-pastoris (L.) Medik. (shepherd’s purse) in soil
… which are capable of absorbing large volumes of water and it has been shown to be of significant ecological importance in terms of seed dormancy, germination and dispersion. However, the effects of the mucilage on the physical properties of soil have not been examined. In this thesis, the …
