Temporal Dynamics of Groundwater Flow Direction in a Glaciated, Headwater Catchment
… groundwater flow in the critical zone of steep headwater mountain catchments is often assumed to mimic surface topography. However, groundwater flow is influenced by other variables, such as the elevation of the water table and subsurface hydraulic conductivity, which can result in temporal …

Effect of Spatial Scale on Hydrologic Modeling in a Headwater Catchment
… were applied to the mountainous Back Creek catchment, located in the headwaters of the Roanoke River in Southwest Virginia. The two models employed were HEC-1, an event based lumped model, and TOPMODEL, a continuous semi-distributed model. These models were used to investigate (a) the issue …

Measuring and Understanding Effects of Prescribed Fire in a Headwater Catchment
Headwater catchments play a large role in the storage and release of water and chemical constituents, thereby influencing downstream flows and water quality. Recent advances in water quality monitoring technologies have created an opportunity to better assess water chemistry variation by using high …

Velocity and celerity in a forested headwater catchment : a combined experimental and modelling approach
… scales, from soil column to hillslope, to a sub-catchment scale analysis in a forested headwater catchment characterised by fractured bedrock. Our field experiments proved the importance of bedrock cleavage orientation in controlling subsurface flow direction and demonstrated the importance of …

Susceptibility Of Headwater Catchment Hydrology To Persistent Droughts And Forest Structure Modification - A Plot To Catchment Scale Analysis
Headwater catchments across the Western United States are critical environments to natural ecosystems and are a vital component of water resources to many communities and industries and may be strongly affected by changing climate and altered disturbance regimes. To better quantify how these …

A Hydropedological Approach to Describing Runoff Generation, Lateral Podzolization, and Spatial and Temporal Patterns of DOC in a Headwater Catchment
… discharge and water chemistry among and within headwater catchments are not well understood. Developing a better understanding of the processes that control these variations is crucial to determining how headwater catchments will respond to changes in climate and land use. This dissertation …

Digital terrain analysis to predict soil spatial patterns at the Hubbard Brook Experimental Forest
… 1-10 m) soil and hydrological variability of headwater catchments may require higher-resolution data that has only recently become available, and both DEM accuracy and the effects of different high-resolution DEMs on topographic metrics are relatively unknown. This study has two principle …

Ecological Benefits of Mitigation on a Large River Mainstem in an Intensively Mined Appalachian Watershed
… Appalachians causes significant alteration of headwater catchments, and these impacts may be offset through implementation of stream restoration projects. As an example, several habitat enhancement structures (cross-vanes and j-hooks) were constructed along a 13.7 km section of the Little Coal …

Catchment Structure Regulates Hydrodynamic Drivers of Chemical Weathering in Shallow Forest Soils
… patterns in chemical weathering in a forested headwater catchment. In the first chapter, relationships between hydrologic behavior, fluxes of weathered elements, and the extent of soil elemental loss across landscape positions are established. The second chapter investigates what specific …

Capturing and Characterizing Soluble Organic Matter Dynamics in Soil Formation Processes
… of podzolization in a northeast glaciated headwater catchment. Findings from the resin study suggest that quaternary amine Cl- resins with a cross-linked polyacrylamide matrix and gel structure have the best suitability for in-situ sampling of DOM over time. While these resins only captured …

Analyzing and modelling of flow transmission processes in river-systems with a focus on semi-arid conditions
… discharge time series itself, was applied to a headwater catchment in Germany, in which runoff are induced by either convective rainfall during the summer or snow melt in the spring. The application showed the following important features: • the differences between runoff measurements were more …
