River flash floods and floods are natural events, which are part of the normal regime of the water leakage of a fluvial organism. Depending on the generating causes, they have a different size and a certain frequency of occurrence in time. The target area of the present study is the Sireasa area in the Danube Delta. In that place, a breakage may occur any time in the defensive dam surrounding the enclosure. This is due to the phenomenon of settlement traveled over time, or due to the possibility of occurrence of t...

The article presents practical problems related to the application of REACH and LCA standards in the construction sector. Chemicals are an essential factor in assessing and managing of all kinds of risk due to their importance as components of materials and their various effects, such as: adverse and beneficial, biophysical and socio-economic. The process of reducing of adverse environmental impact of construction sector on the environment is a subject of increasing attention of scientists and companies. It should...

Throughout the last few years, there has been a global trend to preserve protected green areas. Each nation is responsible for ensuring that such areas are not potentially destroyed by faulty social management and development. Therefore, a sustainable future can only be built with sufficient care for green infrastructure, which once destroyed is almost impossible to restore. Communities should thus actively participate towards protecting their local biodiversity and natural habitats, thereby improving their collec...

An important problem of modern civilization is the aging of societies. The effect of this phenomenon is and will be limited access of enterprises to young and middle-aged employees. This problem also applies to coal mine. First and foremost, young and middle-aged employees work in them. Therefore it will be necessary to undertake actions aimed at stopping already working workers and employing older people in the case of shortages. Extending the employment time in mining enterprises requires a proper approach to th...

Technologies based on photogrammetric and remote sensing sensors represent the usual way for obtaining digital height and position data. This paper is dedicated to LiDAR data filtering for a DEM generation. The main purpose is presentation of a semi-automated method of filtering using mathematical and statistical algorithms for a valid data set. The method involves point cloud data filtering and interpolation. The principle of it is to validate an error free data set and construct the DSM from the last pulse refle...

Spatial information became ordinary for everyday use hidden in different kinds of both paper and web maps, navigation, and map applications. People perceive more than 85% of the information by eyesight. Also, the majority of maps is produced for reading with eyes. Visually impaired including blind people perceive the world differently and have the insufficient amount of possible ways how to investigate the surroundings. Also, creating a particular map for blind people is conceptually different, more expensive and ...
