Radon‐222 as an Effective Tracer to Distinguish Groundwater Circulation Patterns in the Deep Fault‐Controlled Geothermal System

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract Groundwater flow regulated by deep faults remains challenging to trace due to structural complexity. This study applies the noble gas tracer 222Rn combined with hydrochemistry and stable isotopes (δ2H, δ18O) to distinguish circulation patterns of geothermal springs along a major fault in the Tibetan Plateau.

Research on the diagnosis of leakage hazards in a karst reservoir based on integrated electrical method and geological method

Frontiers in Earth Science
ObjectiveDue to the dual influence of karst features in the dam site area and the unique characteristics of the dam soil, leakage issues in the dam body and dam foundation of a certain reservoir have persisted, limiting the effectiveness of the reservoir.

Modelling spring discharge and solute transport in conduits by coupling CFPv2 to an epikarst reservoir for a karst aquifer

, 2019
Karst aquifers differ from unconsolidated granular aquifers with respect to their groundwater flow behavior because of the dual-permeability characteristics (discrete conduit network coupled to a fissured matrix), the duality of recharge (point vs ...
