Abstract

The Republic of Sakha (Yakutia) having a vast territory located in various climatic zones and a developed network of water bodies exposed to a wide range of natural emergency. The spring-summer floods are the most characteristic. They cause extensive flooding of territories, facilities and infrastructure. This article draws attention to one of the main problems of the natural emergency in the Republic of Sakha (Yakutia). At ice drift on some parts of the river ice gorge is formed and causes flooding of nearby settlements and this brings huge social and material damages to the population and economy of the Republic. The use of satellite information and GIS in emergency situations (ES) allows to perform cartographic modeling of dangerous situation conditions. Cartographic modeling is necessary as a tool to visualize the situation and to simulate its changes. Using satellite images of Landsat 8, the zones of a settlement flooding are revealed and according to them the map of zones of the district subject to spring flood is created in the ArcGis program. Damage calculation is performed with the use of the «Guideline on the assessment of damage caused by large-scale flooding in the regions of the Far Eastern Federal district», approved by the Ministry of emergency situations in Russia. The decree of the Russian Federation Government on prevention and liquidation of emergency situations and consequences of natural disasters is used to compensate the damage caused to the victims of floods
