Groundwater flooding in Ukraine: what kind of management does it require?

摘要

The development of the groundwater "slow" flooding phenomenon in an area takes place together with the groundwater table rising up to the soil surface. The phenomenon appears in groundwater discharge areas in the form of soils moistening, swamping and flooding. The various causes of groundwater flooding can be grouped as natural (climate, geomorphologic and geological processes) and artificial, which are provoked by human activities. Groundwater flooding facilitates aquifers pollution, soil subsidence and landslides. The phenomenon-related emergency events entail property damaging and technical failures, and rare fatal accidents. Generally such events follow unfavourable climatic anomalies; however, in accordance with long-term observations in the Ukraine the risk of disastrous groundwater flooding tends to stably increase (Jakovlev et al., 2002).
