Integration of a Shallow Soda Lake into the Groundwater Flow System by Using Hydraulic Evaluation and Environmental Tracers

Autor: Petra Baják, Katalin Hegedűs-Csondor, Mia Tiljander, Kirsti Korkka-Niemi, Heinz Surbeck, Bálint Izsák, Márta Vargha, Ákos Horváth, Tamás Pándics, Anita Erőss

Publikováno v: Water, Vol 14, Iss 6, p 951 (2022)

Lake Velence is a shallow soda lake whose water level and water quality show a severely deteriorating tendency in recent years. Until recently, the groundwater component in the lake’s water budget has not been taken into consideration. To integrate

Investigation of the contribution of groundwater to the water budget of a shallow soda lake in Hungary by using stable and radioactive isotopes as natural tracers

Autor: Petra Baják, Katalin Hegedűs-Csondor, Mia Tiljander, Kirsti Korkka-Niemi, Bálint Izsák, Márta Vargha, Tamás Pándics, Ákos Horváth, Anita Erőss

Lake Velence is a shallow soda lake in Hungary that is located in a tectonic subsidence in the southern foreland of the Velence Hills. Since the lake is semi-astatic (the volume and level of water in the lake fluctuates frequently), climate has a ser

Metal anomalies in till in the Sarvlaxviken area, Lovisa, southern Finland

Autor: Kirsti Korkka-Niemi, M. Valkama, Krister Sundblad

Geochemical investigations of till is a widely used method in metal exploration as the till commonly inherits the geochemical signature (including the metal contents) of the parent bedrock. In this investigation, over 2000 till samples were collected

Hydrogeological Characterization Of Crystalline Bedrock Using Borehole Magnetic Resonance At A Mining Development Site, Northern Finland

Autor: Salla Talvikki Eeva, Emilia Koivisto, Kirsti Korkka-Niemi, Anne Rautio, Ryan Gee

Publikováno v: University of Helsinki

The Borehole Magnetic Resonance (BMR) method was tested for measuring porosity and estimating groundwater flow parameters required for hydrogeological modelling in a crystalline rock setting at the Sakatti Ni‐Cu‐PGE mining project site in Norther

Three-dimensional hydrostratigraphy and groundwater flow models in complex Quaternary deposits and weathered/fractured bedrock : evaluating increasing model complexity

Autor: Kirsti Korkka-Niemi, Susanne Charlotta Åberg, Annika Åberg

Greater complexity in three-dimensional (3D) model structures yields more plausible groundwater recharge/discharge patterns, especially in groundwater/surface-water interactions. The construction of a 3D hydrostratigraphic model prior to flow modelli

Autor: Susanne Charlotta Åberg, Annika Åberg, Kirsti Korkka-Niemi

Central Lapland Greenstone Belt is highly prospective for gold and Ni-Cu-PGE deposits. The study area in Sodankylä, in northern Finland, has been glaciated during last ice ages forming complex sedimentary succession with low conductivity till and hi
