Sanford et al. dissolved gas tracer method
Sampling of 3H and 4He environmental tracers from screened groundwater wells to constrain groundwater age distributions and validate numerical model predictions of mixing between modern and pre-modern...
Coupled ParFlow-CLM EcoSLIM groundwater age modeling with matrix diffusion
Coupled integrated hydrologic and particle tracking modeling approach that simulates groundwater flow using ParFlow-CLM and age distributions using EcoSLIM, with matrix diffusion effects incorporated ...
Bayesian MCMC groundwater residence time inference
Bayesian framework using Markov-chain Monte Carlo to infer groundwater residence time distributions from environmental tracer observations while quantifying parameter uncertainties.
Dissolved noble gas groundwater sampling
Collection of dissolved noble gases from groundwater wells using copper tubes with down-hole pumps and back-pressure valves to prevent degassing during sample collection.
