Analysis of roof and grass drainage on the Beznovci chicken house

The thesis analyses the stormwater drainage system in the example of the Beznovci Chicken House. The main objective of the thesis is to compare the actual sewerage system with a theoretical calculation based on professional sizing literature and to highlight the importance of correct sizing for flood prevention during extreme rainfall events.

The research includes an analysis of the constructed roof and grassland drainage system and a comparison with the theoretical calculation of the rainfall volume. The objectives include the determination of the minimum pipe diameter, the checking of the influence of different surfaces on the volume of water, and the study of different types of pipes and drainage methods.

The research methods used include a descriptive and analytical approach and analysis of project documents and theoretical calculations. The work also presents leading companies in the field of stormwater drainage, with a special focus on Hauraton.

The thesis focuses on the analysis of the impact of stormwater on urban areas. Stormwater is a key factor in urban hydrology, as it affects the quality and quantity of water flowing over surfaces such as roofs, roads, and car parks.

A key challenge in managing stormwater in urban environments is to maintain its quality and quantity to minimize negative impacts on the environment and human life. One of the main aspects of stormwater analysis is the determination of the amount of rainfall that flows from areas called catchments.

Contributing surfaces include all surfaces from which rainwater flows and are crucial in calculating the amount of water that enters the sewerage system or runs off into the environment. The rainfall intensity, the geometry of the surfaces, and the runoff and delay coefficients are important parameters in the determination of rainfall.

Various methods and models based on hydrological principles are used in rainfall quantity determination. Among the most common methods are the Curve Number Method, the Rational Formula, and the Rainfall Distribution Method.

These methods allow the estimation of rainfall based on various parameters such as surface roughness, surface slope, and soil type. In addition to the determination of rainfall, it is also important to consider the influence of the urban environment on the quality of stormwater.

In urban areas, stormwater can quickly become contaminated with substances such as oils, salts, heavy metals, and pesticides, which poses an additional challenge for stormwater management.
