“…The Triwaco program [8] was used for numerical simulation of the groundwater flow. This simulation package for groundwater is a program system for a quasi-threedimensional simulation of groundwater flow, based on the Finite Element Method (FEM) [9], [10]. The differential equations of filtration plane groundwater flow follow from Darcy's Law and from the continuity equation [11], [12].…”

The new proposed railway network in the city of Bratislava, which is supposed to be connected to the airport, is an integral part of Trans-European Network for Transport .Certain section of the planned railway should be constructed along Carpathian Mountains through underground tunnels. However, the construction of this underground tunnel will adversely affect the groundwater flow regime. Therefore, it was necessary to establish a 2D finite element numerical model to evaluate the implementation of this railway tunnel on the groundwater regime as well as means of technical measures to reduce the impacts. The paper presents the model result, analyses, prognosis as well as possible methods to control the groundwater level regime in the aquifer that could be affected by the railway tunnel construction.

“…This method is used in practice [27]. The importance of evaluating dewatering data is clear: a better knowledge helps to find a safe method for the water supply [28], it can contribute to the numerical modeling, [29] which is also an effective tool to investigate aquifers, and last but not least, it helps to preserve our underground water resource.…”

The forty years of intensive mine dewatering in the Transdanubian Range contributed to getting high quality and large amount of data about the karstified aquifers, which could not be gained in any other way. In addition to providing the claimed depression to the safety mining under the original karst water level, the scientific investigation of the processes was emphasized. Although the mines were abandoned the data sets could be a great base of additional investigation about the karstified aquifers. This paper presents the evaluation of dewatering data as pumping test data by using many methods.

“…The stream intersecting the central part of the modeled area has these parameters ( Table II). In case of the RIV module simulation it is needed to perform a surface water level simulation in an external application [14] Suitable applications include the U.S. Army Corps of Engineers, Hydrologic Engineering Center's River Analysis System (HEC-RAS) model and Danish Hydraulic Institute (DHI) Mike 11 model. Mike 11 is a 1-dimensional unsteady flow hydraulic model used for the simulation of flow in rivers [15].…”

The aim of this article is the comparison of input options of river boundary condition of MODFLOW-three-dimensional numerical simulation model of groundwater flow. The water level in stream flowing through territory of hydrogeological layer can be computed via three built-in modules: River, Stream and Streamflow-Routing. In this study the code MODFLOW is used to simulate idealized aquifer and stream. The differences between computed groundwater table showed to be minimal, thus in case of modules Stream and Streamflow-Routing they are equally usable as using module River with external one or two-dimensional simulation of surface water flow, which is more time-consuming process. However, this applies only to idealized, simplified conditions of the modeled environment. For more complex simulation of flow in streams with irregular structure of the streambed is necessary to use either an external simulation or use the Streamflow-Routing module, which includes the possibility to enter more complex hydraulic flow parameters in the model.
