The Tague EcoHydrology lab focuses on watershed research, addressing the feedbacks among terrestrial vegetation, surface hydrological processes, and atmospheric conditions. We use a variety of techniques to examine the impact of changes in climate and land use on ecosystem health and water resources.

All are welcome to attend our weekly lab meetings and take part in presentations and scientific discussions. See our Lab meeting schedule & events page for information on each week’s topic or presenter. Meetings are held in the Bren hall lab wing, room 1005.
The goal of this study was to characterise spatial variation in shallow soil moisture at the plot scale by relating the mean of measurements collected in a plot to the standard deviation, as spatial variation of soil moisture over very small areas (<100 m2) can have nonlinear impacts on cycling and flux rates.

In this new publication, RHESSys is used to explore the mechanisms that control the change in water yield following a beetle outbreak. Results indicate that the response to beetle-caused tree mortality is nonlinear – the direction of water yield change was location specific & driven by inter-annual climate variability, .

In this new publication, research revealed fundamental differences in water-use patterns and niche-partitioning of soil water resources among the phylogenetic groups of trees co-occurring in widespread forests around the Mediterranean. RHESSys model simulations show that this partitioning has an important role in the higher productivity of the mixed forest compared to monoculture forests.

In this new Ecosphere publication, fire spread and fire effects are integrated with ecohydrology in the new RHESSys-WMFire model and used to explore contrasting short- and long-term climate effects on fire in the Sierra Nevada.

Last week Naomi Tague presented ‘The Tight Coupling Between Forests and Water – And Why This Matters’ as part of the Oregon State University/Portland State University/USGS hydrology seminar series for the Water Resource Graduate Program‘s Spring 2021 seminar series.
In this publication, RHESSys was used to analyze long‐term changes and annual and seasonal trends in streamflow & transpiration following management strategies of abandoned cropland areas in the Mediterranean basin.

The study in this new publication used the RHESSys model to explore different treatment options after cropland abandonment – illustrating the need to take plant succession and hydrological dynamics into account when designing land management strategies to preserve water resources in Mediterranean mountain areas.
