“…The differential equations of filtration plane groundwater flow follow from Darcy's Law and from the continuity equation [11], [12]. On the basis of the Dupuit-Forchheimer assumption, the equation for steady groundwater flow for each aquifer or its part can be written in the following form [13], [14]:…”

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.

“…The retention capacity and potential of water in the soil affects the water regime of the landscape (Tall and Gomboš, 2013). Retention soil capacity and soil water availability for the crops is different in various soil types (Červeňanská et al, 2016;Červeňanská et al, 2018;Šoltész and Baroková, 2011;Constantin, 2016). Soil types are defined by texture.…”

The results of authors of submitted article are based on knowledge that soil retention capacity and soil water availability for plants is different in various soil types. Soil types are defined by texture. It is expected that different retention capacity of soil and different availability of soil water for plants is reflected in changes of moisture regime in space and time. Moisture regime monitoring results captures these changes. Changes can be statistically and graphically analysed and interpreted. The results gained from three localities of East Slovakian Lowland (ESL) of the year 2015 extreme drought period were selected for presentation. Examined localities differs by texture compound. Localities are representing the heaviest clay soils, lighter clay-loam-silty soils and the lightest loam soils. Soil volume humidity was monitored into the depth of 1.00 m by layers of 0.10 m. All samples were taken in the same day in examined localities. Descriptive statistics method was used for data processing. Graphical representation is processed in form of chronoizophlets, line and column graphs. Different monitoring results of volume moisture and water storage in different soil types are quantified in the article. Winter water refill of soil profile, soil water storage, vertical scatter of soil profile moisture volume, temporal and spatial moisture regime changes and availability of soil water for plant cover was analysed within this quantification. The results of analysis and interpretation of moisture regime in different soil environments are necessary for water management of the country and for the design of adaptive measures for the periods of soil drought.

Modelling hazards impacting the flow regime in the Hranice Karst due to the proposed Skalička Dam

Abstract. This study examines hydrogeological risks associated with the construction of the proposed Skalička Dam in the vicinity of the Hranice Karst. Prompted by the catastrophic floods in 1997, the design of the dam aims to mitigate floods along the Bečva River downstream of the reservoir. However, concerns have been raised regarding the potential disturbance of the natural groundwater regime in the Hranice Karst and the source of mineral waters for the Teplice spa. This is particularly due to the dam's location in an area with limestone outcrops potentially susceptible to surface water infiltration. Previous studies have also highlighted the strong correlation between the water level in the Bečva River and the water level in karst formations such as the Hranice Abyss, Zbrašov Aragonite Caves, and other caves in the locality. To address these concerns, a nonlinear reservoir-pipe groundwater flow model was employed to simulate the behaviour of the Hranice Karst aquifer, and specifically the effects of the dam reservoir's impoundment. The study concluded that the lateral variant of the dam would have a practically negligible impact on the karst water system, with the rise in water level being only a few centimetres. The through-flow variant was found to have a more significant potential impact on water levels and the outflow of mineral water in the spa, with a piezometric rise of about 1 m and an increase in the karst water discharge to the Bečva River of more than 50 %. Based on these results, recommendations for further investigations concerning the design of the dam and its eventual construction were formulated to reduce geological uncertainties and minimise the potential impact of the hydraulic scheme on the hydrogeology of the karstic system.
