Probabilistic Models for Droughts: Applications in Trigger Identification, Predictor Selection and Index Development
… a hard classification of droughts using various hydrologic variables. However, this method does not yield model uncertainty, and is very limited for forecasting upcoming droughts. The primary goal of this thesis is to develop and implement methods that incorporate uncertainty estimation into …

Calibration of Snowmaking Equipment for Efficient Use on Virginia's Smart Road
… presented herein addresses the hydraulic and hydrologic variables and design methodology to implement efficient snowmaking at a transportation research facility. Design variables include nozzle configuration, water pressure and flowrate, compressed air pressure and flowrate, tower orientation, …

Improving Turbidity-Based Estimates of Suspended Sediment Concentrations and Loads
… that contribute to SSC-estimation variance and hydrologic variables that contribute to variance in those physical properties. Results indicated that the inclusion of any of the measured physical properties, which included grain-size distributions, specific surface-area, and organic carbon, in …

EFFECTS OF FLOW REGIME ON FISHES AND FISHERIES: FROM LIFE HISTORIES TO ECOSYSTEM SERVICES
… results suggest that, due to collinearity of hydrologic variables, effects of sampling gear, and scale of analysis, applying and operationalizing the predictions of the TLHM in terms of hydrology may not be straightforward. here is a continued need to match high-quality biological data with …

Snowmelt and rainfall runoff in burned and unburned catchments at the intermittent-persistent snow transition, Colorado Front Range
… Front Range, and wildfire can greatly affect the hydrologic regime through which these inputs are delivered to the stream. However, the specific changes to the hydrologic processes that drive runoff production made by wildfire are not clearly understood. This research examines how wildfire affects …

Trends and interannual variability in snowpack and spring season hydroclimatology in the southwestern United States
… large-scale interactions of land surface hydrologic variables. With additional quantification of how the land surface behaves under changing climate conditions, we may be better able to anticipate future land surface variability and feedbacks and assess model projections with a better …

Satellite-based estimates of net radiation and modeling the role of topography and vegetation on inter-annual hydro-climatology
… modeling impacts of climate change related to hydrologic cycle. The Surface Radiation Budget (SRB) is an important component in the study of land surface processes. Existing SRB retrieval algorithms generally suffer from two major shortcomings: difficulty in dealing with cloudy sky conditions …

The distribution and diversity of an entire assemblage of Plecoptera (stoneflies) inhabiting Indiana, USA
… HUC8 drainage richness was predicted using nine variables, reduced from 116 and subjected to AICc Importance and Hierarchical Partitioning. AICc Importance revealed four variables associated with Plecoptera species richness, topographic wetness index, HUC8 area, percent soil hydrologic group C/D, …

Restoration and Water Management in the Atchafalaya River Basin, Louisiana
… among 12 ecosystem services and related variables in the ARB. Results from Indicators of Hydrologic Alteration were reduced to four management-relevant hydrologic variables using principal components analysis. Multiple regression was used to determine flow-ecology relationships and …

Ecohydrology of Natural and Restored Wetlands in a Glacial Plain
… natural wetlands. Considering that unexpected ecohydrologic behaviors such as drought have been reported as a main cause of unsuccessful restoration over the U.S., understanding and quantifying water movement within the local seeing is imperative to future wetland restoration. </p> <p>From an …
