Comparing Sediment Trap Data With Erosion Models for Evaluation of Forest Haul Road Stream Crossing Approaches
(AMER SOC AGRICULTURAL & BIOLOGICAL ENGINEERS, 2017-01-01)Soil erosion and sediment delivery models have been developed to estimate the inherent complexities of soil erosion, but most models are not specifically modified for forest operation applications. Three erosion models, ... -
Mineral weathering and podzolization control acid neutralization and streamwater chemistry gradients in upland glaciated catchments, Northeastern United States
(2019-02-26)Headwater streams in the White Mountains, NH, United States have been shown to have downstream gradients of increasing pH and concentrations of base cations coupled with decreasing concentrations of aluminum. A two-stage ... -
Stream Runoff and Nitrate Recovery Times After Forest Disturbance in the USA and Japan
(American Geophysical Union, 2018-09-01)To understand mechanisms of long-term hydrological and biogeochemical recovery after forest disturbance, it is important to evaluate recovery times (i.e., time scales associated with the return to baseline or predisturbance ... -
Time-Varying Storage-Water Age Relationships in a Catchment With a Mediterranean Climate
(American Geophysical Union, 2018-06-01)Recent studies on the relationships between catchment storage and water ages using Travel Time Distributions (TTDs), Residence Time Distributions (RTDs), and StorAge Selection (SAS) functions have led to the hypothesis ... -
Modeling wet headwater stream networks across multiple flow conditions in the Appalachian Highlands
(Wiley, 2018-05-25)Despite the advancement of remote sensing and geospatial technology in recent decades, maps of headwater streams continue to have high uncertainty and fail to adequately characterize temporary streams that expand and ... -
Thermal and Hydrodynamic Changes under a Warmer Climate in a Variably Stratified Hypereutrophic Reservoir
(MDPI, 2018-09-19)We quantified effects of future climate warming on temperature and stability in a variably stratified, hypereutrophic reservoir with large fluctuations in water level by calibrating a 2-D model (CE-QUAL-W2, version 3.7.1, ... -
Integrating Climate Forecasts with the Soil and Water Assessment Tool (SWAT) for High-Resolution Hydrologic Simulations and Forecasts in the Southeastern U.S.
(MDPI, 2018-08-29)This study provides high-resolution modeling of daily water budget components at Hydrologic Unit Code (HUC)-12 resolution for 50 watersheds of the South Atlantic Gulf (SAG) region in the southeastern U.S. (SEUS) by ... -
The evolution of root-zone moisture capacities after deforestation: a step towards hydrological predictions under change?
(2016)The core component of many hydrological systems, the moisture storage capacity available to vegetation, is impossible to observe directly at the catchment scale and is typically treated as a calibration parameter or obtained ... -
Network analysis reveals multiscale controls on streamwater chemistry
(Natl Acad Sciences, 2014-05-13) -
Use of color maps and wavelet coherence to discern seasonal and interannual climate influences on streamflow variability in northern catchments
(Amer Geophysical Union, 2013-10-01)The higher midlatitudes of the northern hemisphere are particularly sensitive to change due to the important role the 0 degree C isotherm plays in the phase of precipitation and intermediate storage as snow. An international ... -
Temporal dynamics of catchment transit times from stable isotope data
(Amer Geophysical Union, 2015-06-01) -
Threshold changes in storm runoff generation at a till-mantled headwater catchment
(Amer Geophysical Union, 2010-07-20) -
Hydrological connectivity of hillslopes and streams: Characteristic time scales and nonlinearities
(Amer Geophysical Union, 2010-10-30) -
Cross-regional prediction of long-term trajectory of stream water DOC response to climate change
(Amer Geophysical Union, 2012-09-22)There is no scientific consensus about how dissolved organic carbon (DOC) in surface waters is regulated. Here we combine recent literature data from 49 catchments with detailed stream and catchment process information ... -
Network analysis reveals multiscale controls on streamwater chemistry

Searching for biogeochemical hot spots in three dimensions: Soil C and N cycling in hydropedologic settings in a northern hardwood forest
(Amer Geophysical Union, 2014-08-01)Understanding and predicting the extent, location, and function of biogeochemical hot spots at the watershed scale is a frontier in environmental science. We applied a hydropedologic approach to identify (1) biogeochemical ... -
Organizing groundwater regimes and response thresholds by soils: A framework for understanding runoff generation in a headwater catchment
