The aim of this bachelor thesis is the analysis of the subsurface water level regime in the Abrod area. The analysis is based on graphs. They show the progress of the subsurface water level in the probes, rainfall totals and water states. The analysis consists of comparation of these data and sears for the correlation between water states, rainfall and subsurface water level totals. All these data were observed for the period of 2001 -- 2013 years. In the chapters, the Abrod area is observed, its location, structure and environmental conditions. The paper contains large information about subsurface water, the usage of subsurface waters their location, the factors influencing subsurface water and the areas where it is measured and the methods of exploring its location.
