NATURAL DISASTERS AND SURFACE AND SUBSURFACE WATER POLLUTION RISK ASSESSMENT FOR SOME REGIONS OF GEORGIA

摘要

In the present paper, some hydrological specifications of Georgian water resources are presented. The river Rioni's possible pollution by oil in a period of flooding is studied by numerical modelling. Some results of the investigation of pollution of Georgia's largest river, the River Kura, are also given. With the purpose of studying subsurface water pollution by oil in case of emergency spillage, the process of oil penetration into a soil with a flat surface containing pits are given and analyzed. Results of calculations have shown that the possibility of surface and subsurface water pollution due to accidents on oil pipelines or railway routes is high.
