Article
One of the most significant current discussions in fluid transport industry is how to prolong the service life of a metallic pipeline system under severe physical and chemical conditions. Electrochemical corrosion is a persistent problem, causing material degradation and sometimes resulting in serious consequences. Here more than 150 three-point be...

Hydrogeology-related research activities cover a wide spectrum of research areas at EU and national levels. The KINDRA project (Knowledge Inventory for hydrogeology research, Grant Agreement No. 642047) seeks to create a critical mass for scientific knowledge exchange of hydrogeological research, to ensure wide applicability of research results - i...

Mining and mineral processing operations are usually generating huge amount of tailings. These tailings often gives lots of maintenance work in order to protect environmental resources from heavy metals slowly leaching out of tailing are due to Acid Rock Drainage (ARD) process. Handling leakage could be active or passive such as using of Permeable...

Ground water is a source for drinking and industrial water supply and pollution created by active industrial sites which often cause social, health, and environmental problems. This groundwater eventually drains into adjacent water sources. Filtration Materials for Groundwater: A Guide to Good Practice presents the up-to-date technology of purifica...
Article
The region of the Tokaj-Mountains can be found in North-East Hungary. Although there were some mineral prospecting projects in the 1960s and 1970s the regional water budget and the groundwater flow systems were not known before the complex hydrogeological investigations carried out in the framework. A special prospecting methodology involving geolo...

The Institute of Environmental Management at the University of Miskolc, as a major Hungarian research entity in groundwater management, is dedicated to finding solutions to regional issues of global sustainable water resource management challenges, thus further developing its scope of groundwater management competence. WELLaHEAD is an EU-funded fun...
Article
Pesticides, chlorinated organic compounds and hydrocarbons are among the most threatening soil and groundwater contaminants because of their mobility and persistence in the subsurface, their widespread use, and their health effects. Hazardous chemicals getting into underground medium can be especially dangerous because they may remain persistently...

Recharging from open-surface water resources is investigated as a method for remediation of over-produced and contaminated aquifers. The hydraulic and contaminant modeling using the Modflow-2000 and MT3DMS simulation software are resorted for evaluation of the available options. Methodology is developed and illustrated for reviewing the alternative...
Conference Paper
Full-text available
A complex hydrogeological study was carried out in the framework of the CIVAQUA program organized by the Trans-Tisza Region Environmental and Water Authority to provide the multifunctional artificial recharge of Great-Forest in Debrecen, East-Hungary. Due to several decades of overproduction of groundwater resources, the groundwater heads below the...

This paper illustrates how sensitivity analysis and a worst-case scenario analysis can be useful tools in risk assessment of groundwater pollution. The approach is applied to a study area in Hungary with several known groundwater pollution sources and nearby drinking water production wells. The main concern is whether the contamination sources thre...
Article
The inversion methods should gain more practical applications in the different fields of hydrogeology. Based on the so-called response equations, the parameters of the hydrogeological models are determined during the solution of the inverse problem. Some new inversion algorithms connected to well hydraulics, geohydrology and groundwater flow modeli...

Comparative risk assessment is a natural tool for decision making regarding transboundary environmental issues. A workgroup of environmental experts met during the NATO Workshop over three days and addressed the state of the practice of comparative risk assessment and its applicability in an international context. Discussion of the application of c...

During past decades, several million tons of aluminum industry wastes have been dumped, without a bottom lining system, right on the shore of the Danube River in northwest Hungary. The resulting red sludge ponds pose two major threats to the environment: drinking water resources could be polluted by infiltration, and wind erosion contaminated surro...
Article
A projekt célja a telített és telítetlen közegbeli szivárgás és szennyeződés terjedés vizsgálata volt. Mivel a probléma legkritikusabb része a számítások adatigényének megfelelő szintű kielégítése, ezért a kutatás során az anyag és transzportjellemzők meghatározásának automatizálása felé fordultunk. Ebből a célból egy automatikus szemcseméret elosz...

A kutatási munka során a következő feladatokat oldottuk meg: - Egy új kockázstelemzési módszert dolgoztunk ki a hulladéklerakók veszélyeztető potenciáljának a meghatározására, amely alkalmas a bezárandó lerakók prioritási listájának az összeállításához, és az esetleges alternatív lezárási lehetőségek megítéléséhez - Megadtuk a meglévő lerakók végle...
Article
A kutatás keretében lehetőség volt olyan vizsgálatok, elemzések és módszerfejlesztések elvégzésére, amelyek segítségével a determinisztikus megközelítés és leírás helyett a valószínűségelméleti és geostatisztikai alapú modellszemlélet erősíthető a hidrogeológiában és a hidrogeológiai modellezésben. A különböző hidrogeológiai modellekben a modellpar...

CHPM2030 aims to develop a novel and potentially disruptive technological solution that can help satisfy the European needs for sustainable energy and strategic metals in a single interlinked process. Working at the frontiers of geothermal resources development, minerals extraction and electro-hydrometallurgy the project aims at converting ultra-deep metallic mineral formations into an “orebody-enhanced geothermal system” (EGS) that will serve as a basis for the development of a new type of facility for “Combined Heat, Power and Metal extraction” (CHPM). In the technology envisioned the metal-bearing geological formation will be manipulated in a way that the co-production of energy and metals will be possible, and may be optimised according to the market demands at any given moment in the future. The work plan has been set up in a way to provide proof-of-concept for the following hypotheses: 1. The composition and structure of orebodies have certain characteristics that could be used to our advantage when developing an EGS; 2. Metals can be leached from the orebodies in high concentrations over a prolonged period of time and may substantially influence the economics of the EGS by increasing the overall energy output per well and creating new revenue streams from metal sales; 3. The continuous leaching of metals will increase the performance of the system over time in a controlled way and without having to use high-pressure reservoir stimulation, minimizing potential detrimental impacts of both heat and metal extraction, as well as of the environment. The horizontal aim is to provide new impetus to geothermal development in Europe by investigating previously unexplored technology pathways at low-TRL. This will be achieved by developing a Roadmap in support of the pilot implementation of such system before 2025, and full-scale commercial implementation before 2030.
