Hybrid off-river augmentation system as an alternative raw water resource: the hydrogeochemistry of abandoned mining ponds [PDF]

, 2016
The use of water from abandoned mining ponds under a hybrid off-river augmentation system (HORAS) has been initiated as an alternative water resource for raw water. However, it raises the questions over the safety of the use of such waters. In this study,

Antecedent Hydrologic Conditions Reflected in Stream Lithium Isotope Ratios During Storms

Geophysical Research Letters, Volume 51, Issue 17, 16 September 2024.
Abstract Antecedent hydrological conditions are recorded through the evolution of dissolved lithium isotope signatures (δ7 ${\delta }^{7}$Li) by juxtaposing two storm events in an upland watershed subject to a Mediterranean climate. Discharge and δ7 ${\delta }^{7}$Li are negatively correlated in both events, but mean δ7 ${\delta }^{7}$Li ratios and ...

DILSTORE software for ecological status assessment of lakes based on benthic diatoms [PDF]

, 2009
Until recently, only few diatom indices were developed for monitoring littoral zones of lakes. The available indices are not applicable for all lake types because species lists and environmental constraints’ ranges are different.

Water Geochemistry and Stable Isotope Changes Record Groundwater Mixing After a Regional Earthquake in Northeast India

Geochemistry, Geophysics, Geosystems, Volume 25, Issue 7, July 2024.
Abstract Recorded earthquake‐induced changes in hydrogeological systems date back over 2,000 years. As a part of our ongoing hydrogeochemical monitoring effort to study such changes, we collected 406 groundwater samples twice a week between February 2021 and July 2023 from two bore wells in the Kopili fault zone of Northeast India.

Hydrogeochemistry of the Caribou-Poker Creeks Research Watershed [PDF]

, 1982
Bedrock of the Caribou-Poker Creeks Research Watershed dissolves incongruently with a first-order rate constant of about 5 x 10-6 day-1 at 5° C. The resulting solution is potassium-calcium-magnesium rich.
