The Floods Directive has brought a common denominator of flood problem affairs management to the EU but does allow differences in its implementation in the Member States, as they have different geographical, social, and economic conditions. The common goal is a transparent assessment of the situation and reduction or management of flood risks, wherein the Member States can independently and differently select the return periods of high water and the level of risk, which leads to different legal regimes in fl ood areas. Therefore, the spatial placement is typical of individual areas of the river basin (in a Member State, Federal State); different legal regulation may also occur in the placement of interventions in the space on the adjacent banks of an interstate watercourse, which will be shown on the border stretch of the Mura River.
