Types of tasks carried out

• Simulation of groundwater flow
  Groundwater flow models are assembled within various types of tasks. In most cases, these models deal with water balance in a certain area, be it with regard to the usability of the area for drinking water sources or for the purpose of identifying the presumed abstracted volumes that are necessary for drying the space of… Read more: Simulation of groundwater flow
• Transport simulation of the so-called contamination solutes, using oxidation-reduction processes
  These tasks are mostly carried out in relation to the removal of various environmental disasters or old environmental liabilities. These usually are simulations of the transport of solutes of some organic (fuels, solvents, oils or residues from various industrial production) or inorganic contaminants (usually heavy metals), which interact with the aquifer environment thereby affecting the… Read more: Transport simulation of the so-called contamination solutes, using oxidation-reduction processes
• Transport simulation of multiphase systems
  Another field of tasks we address is the travel of contaminants with limited solubility and different bulk density compared with fresh groundwater. Apart from NAPL (Non-Aqueous Phase Liquid), this group includes heavy, highly concentrated brine of various origin.

Tasks carried out

• Balance flow models for the purposes of mining companies
  A bottom line of all these groundwater flow models was the required calculation of the amount of water that flows into the opencast or deep mines in all stages of their existence, including the water inflow after the mine gets closed down. Simulation of water level onset upon the termination of mining was in virtually… Read more: Balance flow models for the purposes of mining companies
• The balance groundwater flow models for the purposes of calculation of the water balance in hydrogeological regions
  CZECH GEOLOGICAL SERVICE, RE-BALANCE OF GROUNDWATER RESERVES IN SELECTED AREAS OF THE CZECH REPUBLIC The objective of the project was to re-evaluate the natural sources of groundwater in 56 selected hydrogeological regions which – combined – account for approximately one third of the area of the Czech Republic. The project comprised 11 activities in total,… Read more: The balance groundwater flow models for the purposes of calculation of the water balance in hydrogeological regions
• Groundwater flow models, including the modelling of an unsaturated zone as a significant part of the project
  Průmyslová zóna Mošnov (Ostrava-Mošnov development area), AZ-Geo s.r.o. – the objective of the mathematical modelling was to evaluate the options of the disposal of rainwater into the groundwater, to examine the interaction of the existing and newly emerging seepage, to examine the impact of seepage on the remediated old environmental burden in the area of Železniční… Read more: Groundwater flow models, including the modelling of an unsaturated zone as a significant part of the project
• OSTRAMO, Landfill (so-called lagoons) and former oil refinery
  The paraffin (lamp oil) and heavy fuel oil refinery was established in 1888. During the Second World War it was converted into a raw mineral oil refinery for military purposes. From the end of the war till the late 1970s it produced and processed a wide range of refinery products, e.g. paste lubricants, oils, asphalt,… Read more: OSTRAMO, Landfill (so-called lagoons) and former oil refinery
• Other transport models for solutes
  SAPREF – Tara Road, Moore Spence Jones (Pty) Ltd – spread of contamination of petrol-based light petroleum hydrocarbons from the pipeline leak at Durban, South Africa. In June 2001 a huge fuel leak was detected at the SAPREF medium pipeline between the harbour and the refinery in Durban. Immediately after the accident, disaster mitigating measures… Read more: Other transport models for solutes
• Transport model for multi-phase systems
  TNPA, New Multi Products Pipeline Project – spread of light non-aqueous phase liquids in the storage area of Durban Harbour, KwaZulu-Natal, South Africa. The subject of modelling was the examination of the possibility of LNAPL spread into the space of the foundation pit being drained. The problem was addressed at two stages: (1) assembly of… Read more: Transport model for multi-phase systems
