The paper presents a forecast on how hazardous exogenous geological processes caused by whether natural or man-caused flooding may affect the condition of infrastructures. The authors propose using an integrated R-score, which is a linear combination of partial criteria R1, R2, R3, R4 of the weighting factor (the weight) ki; these criteria are determined by experts as a function of partial indicators or on the basis of foundation cracks and settlement observation data. Reducing the integrated R-score to nearly zero is what indicates a reduction in the emergency hazards by preventive and protective actions. To address this problem is imperative for cities, where the developed areas are non-homogeneous and vary in time and space. Such areas must be run in accordance with the fundamental principle of geological safety and reliability in the context of actual and potential flooding.
