Matthew Miller
Matt Miller is a Research Hydrologist with the Earth Systems Modeling Branch of the Integrated Modeling and Prediction Division in Boulder, Colorado.
His current research focuses on developing integrated approaches for assessing water availability, including novel approaches for interpreting large data sets to quantify the relationships between water quality, hydrology, land use, and climate at watershed, regional, and national scales. A major theme of Matt’s research is improving process-level understanding of groundwater-surface water interaction and incorporating this understanding into water budget and water quality models. Matt is currently the Project Manager for an Integrated Water Availability Assessment (IWAAs) project in the Upper Colorado River Basin. This project aims to provide insight into how past, present, and future snow conditions – including amount, timing, melt, and transitions from snow- to rain-dominated systems – impact water supply (quantity and quality) and the ability to meet demand.

The influence of reservoirs, climate, land use and hydrologic conditions on loads and chemical quality of dissolved organic carbon in the Colorado River
Longitudinal patterns in dissolved organic carbon (DOC) loads and chemical quality were identified in the Colorado River from the headwaters in the Rocky Mountains to the United States-Mexico border from 1994 to 2011. Watershed- and reach-scale climate, land use, river discharge and hydrologic modification conditions that contribute to patterns in DOC were also identified. Principal components anaAuthorsMatthew P. MillerFreshwater DOM quantity and quality from a two-component model of UV absorbance
We present a model that considers UV-absorbing dissolved organic matter (DOM) to consist of two components (A and B), each with a distinct and constant spectrum. Component A absorbs UV light strongly, and is therefore presumed to possess aromatic chromophores and hydrophobic character, whereas B absorbs weakly and can be assumed hydrophilic. We parameterised the model with dissolved organic carbonAuthorsHeather T. Carter, Edward Tipping, Jean-Francois Koprivnjak, Matthew P. Miller, Brenda Cookson, John Hamilton-TaylorTemporal trends in algae, benthic invertebrate, and fish assemblages in streams and rivers draining basins of varying land use in the south-central United States, 1993-2007
Site-specific temporal trends in algae, benthic invertebrate, and fish assemblages were investigated in 15 streams and rivers draining basins of varying land use in the south-central United States from 1993–2007. A multivariate approach was used to identify sites with statistically significant trends in aquatic assemblages which were then tested for correlations with assemblage metrics and abioticAuthorsMatthew P.

MizeWater quality of the Chokosna, Gilahina, Lakina Rivers, and Long Lake watershed along McCarthy Road, Wrangell-St. Elias National Park and Preserve, Alaska, 2007-08
The Chokosna, Gilahina, and Lakina River basins, and the Long Lake watershed are located along McCarthy Road in Wrangell–St. Elias National Park and Preserve. The rivers and lake support a large run of sockeye (red) salmon that is important to the commercial and recreational fisheries in the larger Copper River. To gain a better understanding of the water quality conditions of these watersheds, thAuthorsTimothy P. Brabets, Robert T. Ourso, Matthew P. Miller, Anne M. D. BrasherDifferences in macroinvertebrate community structure in streams and rivers with different hydrologic regimes in the semi-arid Colorado Plateau
Aquatic macroinvertebrates are sensitive to changes in their chemical and physical environment, and as such, serve as excellent indicators of overall ecosystem health. Moreover, temporal and spatial differences in macroinvertebrate community structure can be used to investigate broad issues in aquatic science, such as the hypothesis that changes in climate are likely to have disproportionately larAuthorsMatthew P. Miller, Anne M.D. BrasherHyporheic exchange and fulvic acid redox reactions in an alpine stream/wetland ecosystem, Colorado front range
The influence of hyporheic zone interactions on the redox state of fulvic acids and other redox active species was investigated in an alpine stream and adjacent wetland, which is a more reducing environment. A tracer injection experiment using bromide (Br-) was conducted in the stream system. Simulations with a transport model showed that rates of exchange between the stream and hyporheic zone werAuthorsMatthew P. Miller, Diane M. McKnight, R.M. Cory, Mark W. Williams, Robert L.
