Modeling hydrologic processes associated with soil saturation and debris flow initiation during the September 2013 storm, Colorado Front Range
… slopes (SFS). A few previously-published soil moisture observations suggest that SFS were wetter than north-facing slopes (NFS) during the event, which would contrast with soil moisture patterns observed during dry conditions. Various causes have been hypothesized for the preferential …

Evaluation of sampling techniques to characterize topographically-dependent variability for soil moisture downscaling
Soil moisture patterns are an important consideration in many catchment-scale hydrologic applications. Unfortunately, estimating soil moisture patterns at resolutions that are appropriate for these applications (e.g., grid cells with a linear dimension of 10 to 50 m) is difficult. Downscaling …

Use of global datasets for downscaling soil moisture with the EMT+VS model
… models provide coarse-resolution (9-40 km) soil moisture estimates, but various applications require fine-resolution (10-30 m) soil moisture patterns. The Equilibrium Moisture from Topography, Vegetation, and Soil (EMT+VS) model downscales soil moisture using fine-resolution topography, …

The effect of altered rainfall seasonality on post-fire recovery of Fynbos and Renosterveld shrublands in the Cape Floristic Region
Shifting climate patterns are a cause for concern for natural ecosystems globally. Of particular concern is the effect of climate change on fire-prone, Mediterranean-type shrublands globally because of the heightened sensitivity of post-fire vegetation to environmental conditions. In this thesis, I …

The role of soil moisture and weather patterns for flood occurrence and characteristics at the river basin scale
… River basin as an example, a classification of soil moisture, a key variable of pre-event conditions, is developed and a probabilistic link between patterns of soil moisture and flood occurrence is established. The soil moisture classification is applied to continuously simulated soil moisture …

Enhanced Soil Moisture and Streamflow Estimation in Ungauged or Data-Scarce Watersheds
… particularly in semi-distributed frameworks like Soil and Water Assessment Tool (SWAT). Clear conceptualization is critical to realize adequate representation of internal hydrologic processes, particularly in saturated excess runoff dominated watersheds where the spatio-temporal dynamics of …

Growth and Physiology of Several Urban Tree Species in Soils Disturbed by Construction Fill or Compaction
… to determine the effects of applying fill soil around existing trees and mechanisms for species tolerance to soil compaction, both common site disturbances in urban forestry. Groups of 22-year-old white oak (Quercus alba) and 13-year-old sweetgum (Liquidambar styraciflua) were subjected to …

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, …

Soil moisture dynamics and soil moisture controlled runoff processes at different spatial scales : from observation to modelling
Soil moisture is a key state variable that controls runoff formation, infiltration and partitioning of radiation into latent and sensible heat. However, the experimental characterisation of near surface soil moisture patterns and their controls on runoff formation remains a challenge. This subject …

SOIL MOISTURE VARIABILITY: IMPLICATIONS FOR THE HYDROLOGY, EROSION AND MANAGEMENT OF GULLIED CATCHMENTS IN CENTRAL SPAIN
… in the physical and hydrological properties of soils. Heterogeneity within the soil's physical and hydrological properties can result in pronounced differences in infiltration and soil moisture. The hydrological response of semi-arid landscapes to rainfall events may therefore be spatially …

Budget and fluxes of nitrogen in mountainous agroecosystems in a summer monsoonal climate under intensive land use
… approaches we identified fertilizer N as well as soil Nmin as the dominant N input sources. As fertilizer N application was the major N input source (>50%), its reduction is the major scope of action for N savings at the field scale. A closely linked action is the synchronization of fertilizer N …
