Influence of stormwater control measures on watershed hydrology and biogeochemical cycling
… and nitrogen cycling throughout entire developed watersheds are lacking. First, this work addresses this gap in knowledge by empirically relating hydrologic regimes at sixteen urban watersheds in Charlotte, NC, USA to a series of metrics that describe the extent of urban development and mitigation …

Modeling the Cumulative Effects of Forest Fire on Watershed Hydrology: A Post-fire Application of the Distributed Hydrology-Soil-Vegetation Model (DHSVM)
The Distributed Hydrology-Soil-Vegetation Model (DHSVM) was applied to the Eightmile Creek watershed in western Montana. The purpose of this research was primarily to assess the applicability of the model as a cumulative effects assessment tool in the post-fire landscape of a forested watershed in …

Sensitivity and uncertainty analysis in hydrological modeling: a case study of South Chickamauga Creek watershed using BASINS/HSPF
… developed for simulating surface and sub-surface hydrology, and creek flows in the South Chickamauga Creek Watershed, TN. The HSPF model was calibrated against USGS observed data from January 2013 to December 2017 and was validated for the period January 2018 to October 2019. Parameter Sensitivity …

Vegetated Swales in Urban Stormwater Modeling and Management
… quality swales distributed among upstream sub-watersheds had on watershed hydrology. The study was also posed to determine how certain design parameters can be dimensioned to increase runoff reduction according to the following modeling scenarios: base, base check dam height, minimum check dam …

Hydrologic Modeling of Irregular Tile Drainage Systems
… of irregular tile networks on Midwestern watershed hydrology. Several issues were identified as pertinent to this specific task: solving the problem of flow to a single tile drain, addressing irregular tile networks at the watershed scale and integrating the dominant hydrologic processes. …

Snow Hydrology and Streamflow Response to Snowmelt: A Case Study on SWE Dataset Comparisons, Regional Water Balance, and Snowmelt-Induced Runoff within the Smith River Watershed, Montana
Seasonal snowpacks in snow-dominated watersheds across the western United States play a critical role in sustaining regional water resources by delaying runoff and regulating streamflow. This research examined snow hydrology in the Smith River Watershed, located in Montana, USA, over five water …

Fish and Habitat Relations at Multiple Spatial Scales in Cheyenne River Basin, South Dakota
… and diversity among 22 sites in four tributary watersheds (Cherry, Elk, Elm, and Plum basins). Distance to mainstem river (Cheyenne or Belle Fourche rivers) was the best model and overall parameter for fish species richness and diversity. The ratio of impoundment area to watershed area, an …

Utilization of the Distributed-Hydrology-Soil-Vegetation-Model (DHSVM) To Quantify Streamflow Changes and Slope Failure Probability Following the Snow-Talon Fire Near Lincoln Montana, USA
… weather and disturbances can influence the hydrology of a watershed. Understanding what is influencing changes in streamflow following fire can be difficult due to lack of data or models running at inappropriate resolution. In dealing with the large spatial extent of approximately 37,000 …

Biotic and abiotic responses to rural development and legacy agriculture by southern Appalachain streams
… at multiple scales throughout a streams' watershed using hydraulic modeling. The travel time required for water to drain from the watershed to a stream reach provided a continuous index to delimit watershed sub portions along a spatial continuum. Within travel time zones (TTZs), I consider …

The influence of urbanization on runoff generation and stream chemistry in Massachusetts watersheds
… in the United States and has implications for watershed hydrology and water quality. Here I evaluate the effect of integrated landscape features (e.g., percent residential or developed) and watershed-scale attributes influenced by urbanization on stream nutrient concentrations in headwater …

Modeling Intermittent and Perennial Headwater Stream Origins In North Carolina.
… the upland landscape and larger streams within a watershed, affect watershed hydrology. Yet current widely available maps inadequately depict headwater streams, underestimating channel length or omitting channels entirely. Intermittent and perennial headwater streams each provide unique habitat. …

Beaver moderated fire resistance in the North Cascades and potential for climate change adaptation
… more intense fires. Intense burns can alter watershed hydrology, increasing the potential for harmful channel incision, which impairs riparian ecosystem function by lowering the water table, disconnecting floodplains from aquatic environments. However, wetlands and functioning riparian zones …

Impacts of Stormwater Management Practices and Climate Change on Flow Regime and Channel Stability
… but increased intensity, will likely shift watershed hydrology towards a flashier regime, exacerbating channel erosion. To address these shortcomings, a multicriteria design approach for SCMs is required, considering local sediment transport capacity and the complexities of urban catchments …

The Varying Effects of Climate And Landscape Changes on Increased River Flows In Minnesota Watersheds
… climate studies have not considered the roles of watershed antecedent moisture conditions and runoff storage in their proxies of potential flood impact, nor explored any direct observational evidence of intense rain event links with flooding. Therefore, to better understand the relationships …
