Abstract

The authors of the article analyzed the technique of geoinformation modeling of flooded areas of the river valley. There has been created an animated GIS model of flooding of the object under study - a section of the river valley Yesil near Petropavlovsk (North Kazakhstan region), which is subject to annual intense flooding. The scenario was modeled on the basis of hydrological characteristics, information on water rises levels for a certain period, as well as relief data using the tools of ArcGIS|ArcScene. The authors used such methods as comparative geographical, cartographic, observation, field methods, and GIS technologies. The study consists of several stages, which include such tasks as the collection and generalization of analytical data on the hydrological regime, spring flood, and flood phenomena on the Yesil river, the creation of a digital relief model based on SRTM data, the creation of a forecast model of flooding near Petropavlovsk. The results obtained can be useful for planning and carrying out measures to prevent emergencies related to flood events on the river.
