https://doi.org/10.4467/2353737XCT.15.222.4608The article describes an urban environment and the anthropogenic factors that influence groundwater and soil conditions. Deep building foundations impact on changes in both groundwater flow and soil consistency, which may occur due to filtration phenomena. Suffusion and internal erosion were described, determining the criteria applied for assessment of soil susceptibility to these phenomena. The results of numerical modelling executed with Visual Modflow software are presented. It is stated that the creation of deep building foundations in an extensively urban area may influence the groundwater and soil conditions.

This paper presents the results and the process of numerical analysis of a selected section of the concrete dam in Roinów. The calculations were carried out for two different variants: the gravity section and the buttress section. The effects of the geometry on the temperature distribution inside the section, and the effect of the temperature on displacements, were examined.

https://doi.org/10.4467/2353737XCT.15.231.4617This paper presents an analysis of possible uses of contemporary data acquiring methods for elaborating hydrotechnical object numerical models. The subject is considered in two aspects – preparation of a geometrical model based on the results of a geodetic survey of the structure as well as subsoil parameters, and data acquisition for building material characteristics. The results presented for non-invasive measurements of hydrotechnical concrete parameters and geometry of the modelled object are based on the example of Rożnów Dam. The research uses data obtained by terrestrial laser scan and sclerometer tests (taken with a S chmidt hammer).
