Modeling and Forecasting flooded areas by means of geoinformation technologies

The use of modern methods of spatial analysis based on geo-information technologies (GIT) makes it possible to solve problems of accumulation, storage, updating and analysis of any spatial and/or temporal information, including hydrological, hydrogeological and engineering-geological. Possessing the ability to process such information, modern GIS allow building predictive models, creating scenarios of possible situations for quick and scientifically based decision making.The scientific rationale of geoinformation modeling and flood development forecasting to mitigate their negative impact using GIT is presented. The possibilities are presented and the main directions of the use of geo-information modeling in forecasting and visualization of flooding areas are shown.The use of ArcGIS software in algorithms of geoprocessing models for solving problems of flood forecasting as a tool for quick and visual express analysis is described.
