An interesting and useful topic that can be addressed within the European Union is the issue of transboundary aquifers. Groundwater is often used as an important water resource on both sides of a common state border and can therefore be affected by cross-border waters.
This article is focused on evolution of baseflow from part of the Bohemian-Moravian Highlands. This is a topical issue and, given the current situation, is also often discussed. The problem of groundwater and its recharge is an important (not only) hydrogeological problem, as climatic conditions in recent years, especially low precipitation, have a negative impact on groundwater recharge.
The article describes hydrological and hydrogeological conditions in a small part of the Lišanský stream catchment near Rakovník. Natural conditions of this area have been influenced by human activity from the 15th century.
Many professionals deal with water quality monitoring in the Czech Republic with various goals and various quality of gathered information. The Czech Hydrometeorological Institute (CHMI) has built and developed a unified longterm monitoring system providing comparable high quality data at a nation- al scale.
During 2011–2015 we have studied water springs remaining in big cities. The main objective was verifying the possibility of using local springs as local sources of water in risk situations as failures of water or energy supply systems.
The article deals with the influence of barometric pressure changes on water levels in monitoring wells and other groundwater observation boreholes. An analysis of the problems involved in measuring the groundwater level was performed.
