The paper presents the particularities of accomplishing risk analyses with the purpose of establishing the safety distances � SD, between the pipes belonging to the natural gas national transmission system � NTS and facilities (people, animals, buildings, crops, orchards, forests etc.) placed in the their vicinity. In order to check if the distances between the National Gas Transportation Pipeline- NGTP and neighboring facilities are SD, the authors developed a procedure and a software for the risk assessment, which make use of a set of formulas validated by experimental results presented in the paper and information from the data base (built by the authors and presented briefly in our work) regarding the supervision of the technical state and recording of the accidents that took place in the last 19 years on the NGTP from NTS. Also, in the paper, one describes the way the technical solutions verified using the procedure and the software built by the authors can be selected and ranked (in view of implementation) by applying the ALARP principle and the cost � benefit analysis.

Abstract The work highlights the modeling of water flow in open channels using 1D mathematical model HEC-RAS in the area of interest Lopuchov village in eastern Slovakia. We created a digital model from a geodetic survey, which was used to show the area of inundation in ArcGIS software. We point out the modeling methodology with emphasis to collection of the data and their relevance for determination of boundary conditions in 3D model of the study area in GIS platform. The BIM objects can be exported to the defined model of the area. The obtained results were used for simulation of flooding. The results give to us clearly and distinctly defined areas of inundation, which we used in the processing of Cost benefit analysis. We used the developed model for stating the potential damages in flood vulnerable areas.
