Fault‐Mediated Groundwater‐Surface Water Mixing Amplifies Hydrochemical/Hydrological Dynamics in a Semi‐Arid Volcanic Lake Basin

open access: yesHydrological Processes, Volume 40, Issue 5, May 2026.
Isotopes data help to understand the GW‐SW connectivity, the recharge elevations, and evaporation in a volcanic lake basin. ABSTRACT Understanding groundwater (GW) to surface water (SW) connectivity (i.e., the exchange of water and solutes between aquifers and surface bodies) is increasingly important under changing climate conditions, where ...

Effects of model complexity on karst catchment runoff modeling for flood warning systems

open access: yesJournal of Hydrology X
Severe flood events are deemed more frequent in the near future with a changing climate. Headwater catchments, especially when karstified, exhibit a pronounced susceptibility to swift and substantial responses to precipitation events, leading to flooding.

Hydrogeological investigations of the Palmerston North region : a thesis presented in partial fulfilment of the requirements for the degree of Masters of Science with Honours in Earth Science at Massey University [PDF]

open access: yes, 1990
The Lower Manawatu River Valley and its major tributary the Pohangina River Valley are incised within the marine strata of the South Wanganui Basin. Lining each valley are a flight of both aggradational and degradational terraces.

Hydromagnesite Precipitation in an Ultramafic‐Hosted Alkaline Lake: Insights From Lake Salda for Jezero Crater, Mars

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 5, May 2026.
Abstract Lake Salda (SW Turkey) is one of the most compelling terrestrial analogs for Jezero Crater on Mars due to its highly alkaline, Mg‐rich waters and hydromagnesite‐forming microbialites. This study integrates hydrochemical measurements, saturation‐index modeling, SEM–TEM imaging, and X‐ray diffraction (XRD) analysis to disentangle the biotic and ...

Monitoring of Polychlorinated Biphenyls in the Transboundary Ile River and Characteristics of Its Transformations Along the River’s Discharge

open access: yesApplied Sciences
This study presents the level of polychlorinated biphenyl (PCB) pollution in the transboundary Ile River in 2015, 2018, 2019, 2023, and 2024. PCB contamination of water, as well as the presence of a large number of individual congeners, including ...

Hydrochemistry types of the Bauru Aquifer System in the State of São Paulo

open access: yesRevista Águas Subterrâneas, 2016
Groundwater is used for public supply in 55% of Brazilian municipalities. In the state of São Paulo approximately 72% of the cities, with an estimated population of 5.5 million inhabitants, are fully or partially supplied by groundwater, being Bauru ...

Tubular microfossils from ∼2.8 to 2.7Ga-old lacustrine deposits of South Africa: A sign for early origin of eukaryotes? [PDF]

open access: yes, 2016
Unequivocal evidence for Archean eukaryotic life has been long sought for and is a matter of lively debate. In the absence of unambiguous fossils this debate has focused on biogeochemical signatures and molecular phylogenies.

Using Environmental Tracers to Reduce Uncertainty in Natural Flood Management Modeling

open access: yesWater Resources Research, Volume 62, Issue 5, -Not available-.
Abstract Natural flood management (NFM) is a nature‐based solution that has grown in importance within flood risk policy and management over the last two decades. There is limited evidence on nature‐based solutions' effectiveness, and no accepted best practice on forecasting their performance. To explore NFM effectiveness, we built a hydrological model

Beyond Rock Glaciers: Investigating Meltwater Contribution and Water Quality in High‐Mountain Springs From Different Landforms

open access: yesHydrological Processes, Volume 40, Issue 4, April 2026.
We investigated the water chemistry of springs from different landforms in high‐elevation Alpine catchments. Only in predisposing lithological settings, springs from landforms most likely influenced by ice had a poor water quality with high dissolved concentrations of metals.

Hydrogeochemical Dynamics and Response of Karst Catchment to Rainstorms in a Critical Zone Observatory (CZO), Southwest China

open access: yesFrontiers in Water, 2020
Karst water is vital for local drinking and irrigation but is susceptible to contamination. Hydrochemistry, which is highly related to carbonate weathering in karst catchments, can affect water quality and respond rapidly to climate change.
