Upstream Population Gradient Drives Freshwater Salinization in the Occoquan Watershed
… was found to be dependent upon overland hydrologic flowpaths which connect urban areas to stream networks. The analysis was then broadened to Multiple Linear Regression models of urban and climatological drivers to statistically quantify each driver's relative influence on in-stream …

Digital terrain analysis to predict soil spatial patterns at the Hubbard Brook Experimental Forest
… models (DEMs) has become commonplace in soil and hydrologic modeling and analysis and there has been considerable assessment of the effects of grid resolution on topographic metrics using DEMs of 10 m resolution or coarser. However, examining fine-scale (i.e., 1-10 m) soil and hydrological …

Using Electrical Resistivity Imaging to Relate Surface Coal Mining Valley Fill Characteristics to Effluent Stream Quality
… the interior subsurface structure and hydrologic flowpaths within a series of valley fills and relating that to valley fill characteristics such as age and construction method. We used electrical resistivity imaging (ERI) to investigate the subsurface structure of four valley fills in …

River-Floodplain Connectivity and Sediment Transport Potential: Applications to Sediment Dynamics on Floodplains and Juvenile Freshwater Mussel Settling in Rivers
… channels are supply limited under the current hydrologic regime and identified as net erosional. On the South River floodplain in Virginia, incorporating hydrologic flowpaths as an explicit measure of river-floodplain connectivity can improve predictions of floodplain sediment deposition. Three …

Hydrochemical Dynamics Under Differing Winter Climate Regimes at the Hubbard Brook Experiment Forest
… were largely determined by changes in hydrologic flow, increasing during snowmelt events. The DOC concentration varied among the watersheds and was highly correlated to the winter climate variables for each of the watersheds.</p> <p>End-member mixing analysis (EMMA) revealed differences …

Weathering and soil properties on catenary sequences in forest and alpine ecosystems of the central Rocky Mountains
… along catenary sequences—soil sequences that are hydrologically and topographically connected along hillslopes from higher elevation to lower elevation. Using the catena model, I investigated the manifestation of soil forming factors in conditioning weathering and soil development in the Mountain …
