Influence of Terrain, Vegetative, and Hydraulic Properties on Sediment and Microplastic Accumulation in the Stroubles Creek Floodplain
… were measured along a 1.25 km stretch of Stroubles Creek in Blacksburg, Virginia. Sediment accumulation was measured using tiles with a surface area of 144cm² at 75 locations. Tiles accumulated 4,782g over their two-year deployment. Microplastic accumulation was assessed by taking 15cm3 …

Thermal Evaluation of an Urbanized Watershed using SWMM and MINUHET: a Case Study of Stroubles Creek Watershed, Blacksburg, VA
… The watershed is 14.1 km², and is portion of Stroubles Creek located near downtown Blackburg, Virginia and the main campus of Virginia Tech. Streamflow, water temperature, and climate data were acquired from Virginia Tech StREAM Lab (Stream Research, Education, and Management) monitoring …

Comparison of Hydraulic Function and Channel-Floodplain Connectivity Between Actively and Passively Restored Reaches of Stroubles Creek 11 Years After Restoration
A hydraulic model was developed to determine differences in the hydraulic characteristics of three different reaches of an urban- and agriculturally-impacted stream in southwest Virginia. The three reaches all had cattle excluded from the channel in 2010. The farthest upstream, Treatment 1, was …

Rare Earth Elements as a Tracer to Understand Sediment Fate and Transport in Small Streams
… storm events. Two natural stream bank soils from Stroubles Creek in Virginia were labeled with the REEs lanthanum and ytterbium. The REEs adsorbed equally to both soils and had minimal desorption after several washes with stream water. This suggests that REEs form a dependable natural sediment …

Stream aufwuchs accumulation
… streams near Glen Lyn VA (Phase I) and in Stroubles Creek near Blacksburg VA (Phase II). Depopulation experiments carried out during Phase I supported my hypothesis that accumulation rates are greater in reference than in depopulated streams. The effects of depopulation on Aufwuchs biomass …

Simulation of Runoff and Pollutant Loss in Urbanizing Watersheds
… Virginia, including a subwatershed of Stroubles Creek and a large parking lot on the Virginia Tech campus with a dry pond at its outlet. The model predicted the hydrology and pollutant losses for the year 1999 from the Stroubles Creek watershed within 50% of the observed values after …

Life history and secondary production of Cheumatopsyche spp. in a small Appalachian stream with two different land uses on its watershed
… spp. (Trichoptera: Hydropsychidae) in Stroubles Creek, a 3rd order stream near Blacksburg, Virginia, in order to compare life histories and production dynamics in two reaches with different land-use in a watershed. The upstream section was influenced by urban and agricultural …

Terrestrial Laser Scanning for Quantifying Uncertainty in Fluvial Applications
… to the application of SRD. A streambank on Stroubles Creek in Blacksburg, VA was surveyed six times over two years to measure SBR. Both total station surveying and erosion pins overestimated total volumetric retreat compared to TLS by 32% and 17%, respectively. The error in SBR using …

Evaluation of Rainwater Harvesting on Residential Housing on Virginia Tech Campus
… relates to the management and improvement of the Stroubles Creek watershed in which the majority of the campus sits. Additionally, RWH implementation would benefit sustainable initiatives and provide Virginia Tech additional opportunities for conservation incentives and environmental stewardship …

Stormwater Treatment by Two Retrofit Infiltration Practices
… to water quality and quantity issues within the Stroubles Creek watershed, the Town of Blacksburg and Virginia Tech designed and constructed two innovative stormwater best management practices (BMPs). The goal of this project was to evaluate the effectiveness of a bioretention cell and a …

Impacts of inundation and season on greenhouse gas fluxes from a low-order floodplain
… mesocosms were installed on the floodplain of Stroubles Creek in southwest Virginia. A flood event was simulated in half of these mesocosms in both early spring and mid-summer, which represent extremes in soil moisture and primary productivity on the floodplain. Headspace gases were monitored …

Nutrient release potential during floodplain reconnection: Comparison of conventional and ecological stream restoration approaches
… in the floodplain of a 550-meter reach of Stroubles Creek in the Valley and Ridge province near Blacksburg, VA, to evaluate potential for flushable DOC, TDN, NO3-, NH4+, and SRP content. In addition, an inundation model was developed to evaluate the extent of flooding under the two …

Modeling Channel Degradation at the Watershed Scale: A Comparison of GWLF, SWAT, and CONCEPTS
… used to calculate the estimated mass loading to Stroubles Creek from channel degradation. Two watershed models and one reach-scale model were developed to predict sediment loading to the stream channel from channel degradation. The Generalized Watershed Loading Function (GWLF) was selected to …

Evaluating the Long-Term Morphological Response of a Headwater Stream to Three Restoration Techniques
… project was completed along 1.3 km of Stroubles Creek in 2010. The study site provides a unique opportunity to compare the use of three restoration treatments with different intensities of restoration actions. Following exclusion of cattle from all three sites, the first treatment reach …

Stream Discharge Measurement Using A Large-Scale Paticle Image Velocimetry Prototype
… were taken with each measuring device at Stroubles Creek and Crab Creek. The discharges measured ranged from 0.12 to 63 cfs, which corresponded to a large range of velocities, with both simple and complex flow patterns. Problems were encountered from surface glare reducing image quality at …
