A comprehensive risk assessment of water systems Siberia using GIS technology

Reporter: Nichiporchuk V.V.

Various hydraulic objects, (for example, hydropower station, dams, etc.) have high potential danger. This danger is realized in case of accidents and natural disasters. The wave of the breakout is primary effects of hydrodynamic accidents, associated with the destruction of waterworks. The consequences of such accidents are catastrophic flooding of vast areas, towns and villages, and economic facilities, the loss of life and so on. So far, many safety aspects of hydrodynamic objects are understudied.
The solving of risk analysis problem for hydrodynamic accidents is the integrated use of GIS and WEB technology for ranking territory and objects to the degree of danger and decision support with the threat or emergency. Some attention is paid to this issue in Russia.
The results of many years of work on the assessment of risks of water systems on the example of the Krasnoyarsk Region and the Republic of Sakha (Yakutia) are presented. Studies conventionally are contains three blocks:
ranking areas on flood risk and the size of damage from floods according to many years of observation;
modeling zones of possible flooding in case of accidents at hydrotechnical constructions;
identification of sources and on-line monitoring of hydrological hazards using GIS technology and methods OLAP.
