Abstract The intensive growth in the popularity of Remotely Piloted Aircraft Systems (RPAS) used for recreational, sporting and other purposes, may lead to an increase in accidents and incidents involving them. Therefore, it is advisable to raise the awareness of all users, related to safety issues, to harmonize standards and procedures applicable at international and national level. The article presents the legal conditions for unmanned operations and the risk assessment methods used in areas of human activity. On this basis, an original method of risk assessment in unmanned systems was proposed. The method can be part of the operating instructions of the RPAS operator. At the end, final conclusions were drawn up.

The paper provides genetic classification of lakes in the Czech Republic. We separate lakes to two groups - natural and anthropogenic origin. The genetic classification is based on the classification of lakes according to the way of origination of the lake basin while the geomorphologic viewpoint prevails: glacial lakes, fluvial lakes, karst lakes, lakes dammed-up by landslides, organogenous lakes and anthropogenic lakes. As the anthropogenic lakes we may regard all the water bodies which originated as a consequence of the human activity - mining of mineral resources.
