This master's thesis deals with the analysis of the requirements placed on the technical support information system which should be used in the software developing company. The basic functions of this system are the collecting of information about all kinds of work which the company employees concentrate on and the possibility of statistics generating. Moreover, it is also possible to implement further extensions to the system which will not only enable other functions, that are not related to the primary goal of the system, to be integrated; but also to define new user roles, for which various limited parts of the system will be accessible.

Flood risk assessment in urban areas necessitates the utilization of advanced modeling strategies to accurately depict inundation patterns and potential impacts on communities and infrastructure. This study investigates the impacts of varying 2D modeling strategies on flood risk assessment in the context of the Garonne River flood risk prevention plan. The research focuses on building 2D hydraulic models for the Garonne and Ariège rivers using Telemac 2D, supplemented by models for their tributaries on HEC-RAS. Following calibration, the 1875 reference flood event is simulated, sensitivity analyses were conducted on downstream boundary conditions, Strickler coefficient for the floodplain, and discharge parameters. The results reveal significant impacts of these parameters on the final hazard maps, underscoring the importance of thoughtful consideration in model calibration and parameter selection. It also questions the strategy to base the assessment on an extreme historical flood event with little data to back up the accuracy of the results, or favoring a less extreme event that will lead more accurate results, but with maybe less security.  The study highlights the critical role of high precision topography, particularly in flat and urban areas, where traditional discharge data may be lacking, and precipitation-based methods may prove less effective. The choice of modeling software also emerges as a key factor influencing the accuracy of flood hazard assessments, with variations in parameters and computation methods yielding differing outcomes.  Overall, this research underscores the complex interplay between modeling strategies, parameter selection, and topographic characteristics in urban flood risk assessment. It emphasizes the need for a nuanced approach in choosing flood events for modeling, balancing the availability of data with the accuracy and reliability of results. / Riskbedömning av översvämningar i stadsområden kräver användning av avancerade modelleringsstrategier för att korrekt beskriva översvämningsmönster och potentiella effekter på samhällen och infrastruktur. I denna studie undersöks effekterna av olika 2D- modelleringsstrategier på bedömningen av översvämningsrisker i samband med planen för förebyggande av översvämningsrisker i Garonnefloden. Forskningen fokuserar på att bygga hydrauliska 2D-modeller för floderna Garonne och Ariège med Telemac 2D, kompletterat med modeller för deras bifloder i HEC-RAS.  Efter kalibrering simuleras 1875 års referensflöde, känslighetsanalyser utförs på nedströms gränsvillkor, Strickler-koefficienten för översvämningsslätten och flödesparametrar. Resultaten visar att dessa parametrar har en betydande inverkan på de slutliga riskkartorna, vilket understryker vikten av noggranna överväganden vid modellkalibrering och val av parametrar.  Studien belyser den kritiska roll som högupplöst topografi spelar, särskilt i platta och urbana områden, där traditionella flödesdata kan saknas och nederbördsbaserade metoder kan vara mindre effektiva. Valet av modelleringsprogramvara framstår också som en nyckelfaktor som påverkar noggrannheten i bedömningen av översvämningsrisker, med variationer i parametrar och beräkningsmetoder som ger olika resultat.  Sammantaget understryker denna forskning det komplexa samspelet mellan modelleringsstrategier, val av parametrar och topografiska egenskaper vid riskbedömning av översvämningar i städer.  Den betonar behovet av ett nyanserat tillvägagångssätt när man väljer översvämningshändelser för modellering, och balanserar tillgången på data med resultatens noggrannhet och tillförlitlighet.

The topic Modern Approaches to Designing Electrical Equipment with a Focus on Railway Construction responds to the decision of the Government of the Czech Republic to introduce the BIM method for government over-the-counter contracts from 1 January 2022. The government evaluated the BIM method as an effective tool for digitizing the construction industry. The diploma thesis deals with the method of designing high-current equipment, technologies and distribution on railways according to this new method. The work summarizes information about the present method of design, used high-current electrical equipment on the railway, the near and distant future of railway operation, the organization of administration and maintenance of equipment. It discusses the principle of the BIM method and basic software solutions supporting design activities according to this new method. The Promis.e software published by Bentley is also described in detail, which supports the design of electrical equipment for linear structures according to this method. The BIM method is a means of fulfilling the essence of Construction 4.0. It uses uniform data formats, a common data environment, working with non-graphic information. In the second part of the diploma thesis, the drawing documentation for the sample project of high-current distribution of the railway station was prepared. It was first created using AutoCAD software. After that, the sample project demonstrates the basic principles of the BIM method using Promis.e software. Furthermore, this project is evaluated, both methods of design are compared. The procedure of introducing the BIM method for the design of electrical equipment in a specific design company is proposed and other possible steps in working with the Promis.e software are discussed. The way of creating a and adding element libraries is described. At the end of the diploma thesis it is stated that to successfully master the design work according to the BIM method, it is necessary to have experience with design work in the field, know the principles of the BIM method, choose a suitable software solution, continuously and thoroughly manage these tools and train staff. Under these conditions, it will be possible to make full use of the potential of the BIM method.
