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

open access: yesGroundwater, 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.

Groundwater recharge potential zone modeling in the Wadi Al-Lith Basin, Saudi Arabia

open access: yesApplied Water Science
The management of groundwater resources is crucial in arid and semi-arid regions such as Al-Lith Basin, and therefore, the identification of suitable areas for groundwater recharge is important in solving the problem of water scarcity and ensuring the ...

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

open access: yesGroundwater, 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.

Using CFCs and SF6 for groundwater dating : a SWOT analysis [PDF]

open access: yes, 2010
A knowledge of the residence time of groundwater is of importance in understanding key issues in the evolution of water quality. Chlorofluorocarbons (CFCs) and sulphur hexafluoride (SF6) offer a convenient way of dating waters up to ~60 yrs old.
