ABSTRACT

Situation distance control after flood and inundation is one of the main problem to be solved by space monitoring of emergency situations, developed in Kazakhstan since 2001 y. It is connected with annual emergency situation which is developed in every region of water bodies representing potential or real imminence. During last three years there were heavy floods passed in Kazakhstan, especially in Akmola, Pavlodar, Karaganda regions. There is an acute security issue during spring time inundation, till nowadays there is no science-based methodology for predicting and modeling of flood and inundation using modern methods of GIS- projecting and update remote sensing datas. The ongoing development of own space remote sensing system, usage of KazEOSat -1,2 space craft datas for inundation modeling and predicting, authenticity models studing and DEM construction are the basis for scientific research in hydrological modeling of inundation. With a high resolution DEM, for example, from images shot from unmanned aerial vehicles or laser scanning of a terrain the developed program allows to conduct a more detailed study of the dynamics of terrain flooding and the identification of areas for evacuating the population and moving cattle. The developed program allows to identify the irregularities of cultivated fields surfaces for the use of precision farming methods.

Keywords: flood, inundation, DEM, predicting and modeling, space monitoring
