We also explored how porosity, permeability, and subsurface structure impact stream discharge and groundwater, so feel free to check out the paper for more details!

The Role of Snowmelt and Subsurface Heterogeneity in Headwater Hydrology of a Mountainous Catchment in Colorado: A Model‐Data Integration Approach
Slower snowmelt rates under evergreen forests delay peak streamflow and thereby the onset of baseflow in headwater streams
Lower subsurface permeability in upstream areas slows groundwater releas...

A lateral permeability transition in the subsurface forms a upstream “bathtub” that fills with snowmelt water until it overflows, releasing a second peak of groundwater later in the season.

Evergreen forests delay snowmelt relative to shrubs and grasslands, acting as a buffer that moderates runoff and sustains streamflow over longer periods.

By combining these observations with process-based models, we found that both snowmelt heterogeneity and subsurface structure critically shape headwater hydrology.

I had the luxury of working with the large, high-resolution dataset collected by colleagues in the Watershed Function Science Focus Area led by Berkeley Lab, which allowed us to constrain hydrologic processes far more rigorously than any single measurement type could.

In our recent work, we explored this question by bringing together multiple datasets that are rarely available in mountain headwaters: continuous snow depths from many locations, groundwater levels, stream discharge, and geophysical surveys.

Reply to the EOS highlight title: Beavers are Not Concerned About Groundwater, I guess beavers can also be concerned about groundwater, especially if their ponds are fed by it! We are now studying this in New England.

We found that beaver pond inundation can amplify groundwater recharge by an order of magnitude, yet the fate of that recharge depends critically on subsurface structure and flow pathways. With thick overlying soils, increased evapotranspiration may offset the gains in groundwater recharge.

In this work (agupubs.onlinelibrary.wiley.com/doi/10.1029/...), we addressed this question by combining in-situ hydrologic measurements, geophysics, and hydrologic modeling, and calibrating our model using a machine learning-based method, the neural density estimator.
