Groundwater flooding risk in the cities of Ukraine: assessment and management

摘要

Development of the GWF phenomenon in an area takes place with the rising of the groundwater table up to the soil surface. The phenomenon appears in groundwater discharge areas in the forms of soils moistening, swamping, and flooding. In the urban areas of Ukraine it is often developed to a hazardous scale under the impact of a set of various causes and factors, and it results in complex changes in environmental conditions (Jakovlev et al. 2002). Local characteristics of urban development and geology determine the degree of GWF hazard related to an object (area or construction), and the vulnerability of the object to the hazardous impact. Assessment of GWF risk in urban areas might be useful for decision making to ensure geological safety, and during the process of development national and local actions plans (Chebanov and Konoplia 2010).
