Groundwater flow models: these are computer simulations that help predict the reactions that may occur in groundwater depending on time and external influences, created on the scale of the geological environment containing groundwater. Quantitative and qualitative properties related to groundwater are revealed as a result of modeling. It produces data with the desired accuracy for decision-makers in projects such as investigating the effects of mining, environmental or civil activities, ensuring the sustainability of groundwater use. Mitto Consultancy works with hydrogeologists and academics specializing in groundwater modeling projects. It uses the leading software and technology infrastructure offered by the day.”
