Concentration-discharge (C-Q) relationships have been widely applied to infer integrated hydrologic and biogeochemical processes at the catchment-scale. Apart from event hysteresis or comparisons between catchments, relatively little attention has been given to the “noise” within long-term C-Q patterns. We analyze over two decades of historic data from 10 streams in...

Wastewater reuse is a growing application in many areas of the world as water scarcity is becoming a major issue due to climate change and exponential population growth. In Colorado, water reuse is becoming more viable because of drought and increased water demand. However, chemical contamination from industrial and domestic...

Many hydrologic features in the polar regions will be impacted by increasing temperatures because of climate change. One of these such features is Aufeis (also known as Icings) which are large sheets of ice that form in river channels that can stay frozen well into summer. These features can be...

Nearly 80% of the United States’ freshwater originates in forested landscapes at risk of wildfires (United States Geological Survey (USGS), 2018), which influence both the terrestrial landscape and hydrologic regime by introducing a heterogeneous spectrum of thermally altered carbon compounds, known as pyrogenic carbon (PyC) (Bird et al., 2015). Given...

The Ganges-Brahmaputra-Meghna (GBM) rivers carry a massive sediment load that feeds the world’s largest depositional system: the GBM megadelta. The mass of sediment transported annually by the GBM rivers has not been well constrained; previous estimates range between 0.5 and 2.4 BT/year. The present study attempts to resolve the sediment...

This presentation reveals the Colorado River Basin (CRB) Robustness Analysis web application. Robustness analysis is the process of simulating management alternatives in an ensemble of plausible future States of the World (SOW), then using statistical functions, called robustness metrics, to quantify the performance of each alternative when “stress-tested” in the...

Reservoirs are typically considered too young and dynamic to validate paleolimnological analysis (Filstrup et al. 2010). Using biological and mineralogical proxies, three shifts were identified in the history of Possum Kingdom Lake, successfully demonstrating the application of paleolimnology in reservoirs. The trends documented may provide insight into the factors driving...

The drought conditions in the Navajo Nation are severe to exceptional, and observed across the more than 70,000 square kilometers. The Navajo Nation is the largest land-based tribe in the United States that experiences impacts brought on by subtle changes in precipitation. Evaluation of precipitation from 2002 to 2015 water...

In forested basins, the amount of snow that accumulates on the ground depends on how much snowfall is intercepted in the forest canopy and the subsequent partitioning of canopy snow into sublimation, unloading, and melt drip. However, the amount of precipitation intercepted in forest canopies is rarely measured, and existing...

Given the importance of groundwater in sustaining Upper Colorado River Basin (UCRB) streamflow (over 50% of streamflow originates as baseflow), effective management of water resources in the basin requires estimates of how baseflow may change under projected climatic changes. We applied projections of future climate to a calibrated hybrid statistical-deterministic...
