Climate change threatens water resources in snowmelt‐dependent regions by altering the
fraction of snow and rain and spurring an earlier snowmelt season. The bulk of hydrological …

Drainages are important features of semiarid landscapes because they are areas where
surface water, groundwater, and terrestrial and aquatic ecosystems converge. Management …

Abstract The Pajarito Plateau is an important source of abundant potable groundwater for
Los Alamos National Laboratory (LANL) and the communities of Los Alamos and White …

Reduction of toxic Cr (VI) to less toxic Cr (III) is an important process for attenuating Cr (VI)
transport in groundwater. This process results in immobilization of chromium as Cr (III) and …

We estimate the travel time of percolating water through a deep vadose zone at the regional
scale using a transfer function model and a physical based conceptual flow model (Hydrus …

A generalized dual porosity method (GDPM) has been developed to incorporate sub-grid
scale heterogeneity into large-scale flow and transport simulations. The method is spatially …

Abstract Study Region This study focuses on the headwaters of the Upper Rio Grande basin,
the Pajarito Plateau, northern New Mexico, USA. Study Focus Our work examines 2050s …

A series of calculations and model predictions were used to evaluate the controls on
perched-water conditions and constraints on perching occurrence, persistence, and …

For sites with a contaminant source located in the vadose zone, the nature and extent of
groundwater contaminant plumes are a function of the contaminant flux from the vadose …

A conceptual model is developed to better understand vadose zone vapor‐phase diffusion
within the mesas of the Pajarito Plateau at Los Alamos National Laboratory. We focus on 1 …
