Wind-tunnel modelling & development of emergency software
 Chaloupecká, Hana ; Kluková, Zuzana ; Jakubcová, Michala ; Kellnerová, Radka ; Jurčáková, Klára
The report describes the procedure of work on the two-year project TACR TJ01000383.\nIn the year 2018, relations between characteristics of short-term and long-term gas leakages for an urban area were searched utilizing the database COST ES1006. Then, releases of short-term and long-term gases for a rural area were studied. A dimensionless database I. was created from the data.\nIn the year 2019, the dispersion of short-term and long-term gas releases in an industrial area was studied. The measured data were analysed and the dimensionless database II. was created. The databases I. and II. were utilized for the validation of the model. We developed software as the main goal of the project.

Core of emergency model for urban canopy & Experiments of gas leakages for rural area
 Chaloupecká, Hana ; Jakubcová, Michala ; Kellnerová, Radka ; Jurčáková, Klára
The report consists of two parts.\nThe first part copes with the development of an emergency model core for short-term gas leakages for urban canopy. It is explained a procedure in the development of the model, in which after recording input data describing a gas leakage as an output probability density functions for individual puff characteristics and exposed places are obtained. From the output, one can see for example the most probable puff characteristics, which can occur during an accident as well as extreme cases. This is the biggest difference in comparison with the usually used emergency models, in which only mean puff contours and concentration fields are the output. \nIn the second part, experiments of gas leakages for rural area are described. Fulfilment of similarity criterions in wind-tunnel modelling as well as the experiments themselves and the database development is showed.\n
