The article considers the flooding potential of various urban areas, with a particular focus on Kishinev (the capital city of Moldova). The latter, it relates, is constructed on loessic (clastic, predominantly silt-sized sediment) layers and Sarmatian clays, with its territory subject to regular inundation. The critique notes that researches and engineering studies have been conducted on the residential areas of the city, which has been subject to serious deluges in the past. These documents, the paper says, have attributed the regularity of flooding to its loessic thickness and powdery nature, lithological structure, bedding and distribution conditions, and drainage capacity (all passive factors). These included Kishinev’s geological structure, geomorphology and relief, as well as the lithological structure of its loessic layers. Other factors, the commentary said, comprised its loessic thickness, draining potential and hydrogeological conditions. The study maintains that the municipality’s active flooding factors have inevitably hindered the city’s construction and developmental projects. Subsequently, the research paper turns its focus to different factors – including loessic thickness, draining capacity and submerged water level – that have contributed to the deluge potential of the municipality. The blueprint, in conclusion, covers the weight-coefficients that have influenced various natural factors affecting the flooding speed, with these analogies also relied on to predict the probability of flood recessions.
