THE PROGRAM OF MODELING THE RELIEF FORMATION AND ENVIRONMENTAL DISASTERS Vlad Dziuba Scientific advisors: Moturnak Eugene and Nikolaev Taras School №100, Dnepropetrovsk, Ukraine
Introduction Knowledge of erosion is an accumulative work of water flow necessary for the proper resolution of problems associated with water-power stations and construction of bridges, improvement of inland waterways, agricultural reclamation, and many other practical issues. In addition, the urgent environmental problem is the proliferation of harmful substances in the water or soil, so it is important to know where and how harmful substances are moved as a result of natural disasters, industrial accidents and to predict their effect on the environment. Creating a computer model will facilitate research on these issues.
Fig.2 Experimental model of progress As we can see at Fig.2, water rises up and lands along the flow of a riverbed. Also the left side of a river is has more active flow because there are mountains at the right side. It is obvious that the program predicts a trustful picture of dam bursting.
Method of the investigation For my research I use Ukrainian relief (Fig.1).
Fig.3 Landfall Also I conducted an experiment with a ground water of the landfall (Fig.3). Ability of water to transfer ground is the main power that provides changing of the relief. Fig.1 Ukrainian map
Conclusions
At the beginning the program requires the initial data concerning map, precipitation, materials and amount of control points. Then the program splits the map to control points. Every control point has its own set of layers of different material. The program calculates interaction between different layers at one control point and then between different control points by iteration progress.
The research problem was solved by writing a program. The initial data of the program is information about the terrain and precipitation, properties of the substances that are on the map, such as fluidity and density, the temperature of the environment. Using initial data the program models processes which takes place in real life, while the user can look at processes in different speed mode in two-dimensional or three-dimensional form by different angles and different scales. The program allows to generate computer reliefs as well as to download information about the real location. It allows you to this tool in practice to predict processes of terrain changing and proliferation of harmful substances in the event of accidents, catastrophes or natural disasters. As an example, I used hydroelectric cascade of the Dnieper River and the program predicts which areas will be overblown.
Every material in my program has its own properties. Different liquids have different fluidity, power of ability to transfer solid substances. Different solids have different portability, friability. Also the program allows choosing colors for each material. There are some additional programs. There are Material Editor and Maps Editor. These programs were created for easy opportunity to create new materials and maps.

My experiment is aimed to increase amount of precipitation at the surface of Ukraine and then observe the aftermath. This situation is the same with dam bursting in Kiev region.
