PEST++IES How Many Iterations and Realizations, Finding the Point of Diminishing Returns

Groundwater, EarlyView.
Abstract PEST++IES (White 2018; White et al. 2020) is widely used in the groundwater modeling community for its ability to perform computationally efficient history matching and uncertainty analysis in a highly parameterized context. One primary advantage of using an iterative ensemble smoother is that the number of model runs required per iteration ...

A Categorical Machine Learning Approach to Predicting Areas of Shallow Coastal Groundwater

Groundwater, EarlyView.
Abstract Coastal lowlands are increasingly vulnerable to threats from sea‐level and associated groundwater rise. This study introduces a categorical modeling framework that redefines groundwater depth estimation as a classification problem rather than a continuous prediction task. By dividing groundwater occurrence into multiple depth thresholds (0.9–2.

Aquitardifer: A New Hydrogeologic Term for Geologic Materials with both Aquitard and Aquifer Properties

Groundwater, EarlyView.
Abstract We propose that a new term, aquitardifer, be added to the hydrogeologic nomenclature. Aquitardifer, a blend of the terms aquitard and aquifer, accounts for geologic materials that have properties of both as traditionally defined. Several examples of aquitardifers are provided, as is justification for and applicability of the term.

A Regional Model Comparison between MODPATH and MT3D of Groundwater Travel Time Distributions

Groundwater, EarlyView.
Abstract Groundwater quality changes in wells and streams lag behind changes to land use due to groundwater travel times. Two contaminant transport methods were compared to assess differences in their simulated travel time distributions (TTDs) to streams and wells in the Wisconsin Central Sands.

Analysis of the assessment of the prospects for the burial of CO2 in unexplored aquifer complexes on the example of a facility in the Perm Region

Записки Горного института
One of the most important problems of our time is the annual increase in greenhouse gas emissions into the atmosphere. It is possible to combat this phenomenon by reducing emissions or developing and applying technologies for capturing, storing, using ...
