ABSTRACT
A connection between the airport and railway network is planned as part of the improvement to the transport infrastructure in the Bratislava Region. One section should be built in an underground tunnel along the Carpathian Mountains and it will affect the groundwater flow regime. This was the rationale behind a 2-D finite element numerical model for evaluating the impact of the railway tunnel on the groundwater level regime as well as for introducing technical measures to minimise the impacts. This model was developed and the results show the analysis and prognosis as well as the options for controlling the groundwater level regime in the aquifer affected by the tunnel construction.
