AN INVESTIGATION OF SOIL WATER MOVEMENT ON DRAINED AND UNDRAINED CLAY GRASSLAND IN SOUTH WEST ENGLAND
… and to consider implications for solute movement under natural and drained conditions. Research was conducted on a heavy clay grassland soil in an area of high rainfall (1053 mm a ˉ¹) in South West England. A combined hydrometric and tensiometric study was undertaken within a nested …

Hillslope and watershed scale hydrological processes and grazing management in a Dartmoor catchment, Southwest England
… on the impacts of moorland management on the soils and hydrology of a catchment on Dartmoor. Soil moisture was measured gridwise using TDR on 19 occasions. At 23 sites within this grid, physical properties of the topsoil were obtained. At three locations, tensiometer nests were installed, …

Field and laboratory characterization of soil water desorption properties and comparison of plant available water for two Virginia soils
Soil water movement and desorption studies were conducted on two agriculturally important soil series. The soils selected were the Norfolk soil (a fine loamy, siliceous, thermic, Typic Paleudult) and the Cecil soil (a clayey, kaolinitic, thermic, Typic Hapludult). Water desorption properties were …

TREE ROOT ENCROACHMENT ON LEVEE DRAINAGE SYSTEM
… were tested in v clear columns filled with soil and/or gravel to simulate six different drainage designs. Two New Mexican plants, Rio Grande cottonwood (Populus deltoides ssp. wislizeni) and coyote willow (Salix exigua), were selected, and planted in columns. The results showed roots of both …

THE EFFECTS OF WHOLE TREE HARVESTING ON SITE HYDROLOGY AND SOIL STRUCTURE AT BEDDGELERT FOREST, N. WALES, UK
The ITE biogeochemistry group monitoring solute movement at Beddgelert Forest provided an opportunity to study the hydrology of a steep section of hillslope in a high rainfall environment. The aim of the experiment was to characterise and compare the hillslope hydrologies of one forested and one …

Thermal gradients and water transfer in unsaturated soil.
An investigation into the flux of soil water under the influence of a thermal gradient was conducted in closed soil systems in the laboratory. A thermal gradient was imposed across the sandy loam soil columns and measured continuously for the duration of the experiment. The movement of soil water …

THE HYDROLOGIC CONTROL ON SHALLOW LANDSLIDE TRIGGERING: EMPIRICAL AND MONTE CARLO PYSICALLY-BASED APPROACHES
… by rainfall infiltration, combined with a water table recession (WTR) model that computes the initial water table height to consider in simulating rainfall events with TRIGRS. The Monte Carlo simulator has been applied to the Loco catchment in the Peloritani Mountains in northeastern Sicily …
