Abstract
Abstract. The timeliness of using modern computer programs for modelling flood zones, the consequences of hydraulic accidents, dam breakthroughs, flood and flood forecasting in a complex system of rivers and channels for the prevention of hydro meteorological emergencies is beyond doubt. The use of BIM technologies will make it possible to move from point-based flood risk assessments to areal ones, which will significantly improve the reliability of planned measures to prevent natural and anthropogenic emergencies.The purpose - to perform works on modelling of hydrodynamic accident and forecast of its development by the example of tailings dumps in concentration plant in East Kazakhstan. As the initial data - digital model for the area of work, technical reports on engineering-hydrographical survey, topographic-geodetic works, engineering-geological survey, high-resolution satellite images in a panchromatic survey mode. On the basis of geoinformation modelling methods with use of initial and remote sensing data, final digital terrain model was built in Digital software. The method based on direct hydrodynamic modelling of area flooding was used to calculate hydrodynamic accidents, to model the dynamics of area flooding because of tailings dam break in several levels. The practical result is numerical hydrodynamic modelling of dynamics flooding area because of partial destruction, erosion of embankment dam of tailings concentrator, total area and extent of flooding, as well as the area and depth of partially flooded buildings of residential development was estimated, thematic maps of flooded area were created, as well as maps of water passage with flow velocities during the hydrodynamic accident.Thus, the application of advanced space imagery, GIS technologies in full measure allow for simulating the occurrence, development of hydrodynamic accidents in structures, to determine area, time of flooding.
Highlights
As the world experience shows, the probability of accidents at hydraulic structures has increased over the last 15 years, which is primarily associated with the passage of floods exceeding the design water levels
Hydrodynamic accidents take one of the first places according to the value of consequences and economic damage; using modern computer programs for modeling flood zones, consequences of hydro technical accidents, dam breaks, floods and forecasts for the purposes of emergency prevention is of topical importance
Nowadays there are 643 HS located on the territory of the Republic of Kazakhstan among which 340 structures are used directly for industrial and economic purposes including 270 large and small reservoirs with complexes of hydraulic structures where 62 and 208 reservoirs are of republican and local significance correspondingly
Summary
As the world experience shows, the probability of accidents at hydraulic structures has increased over the last 15 years, which is primarily associated with the passage of floods exceeding the design water levels. Hydrodynamic accidents take one of the first places according to the value of consequences and economic damage; using modern computer programs for modeling flood zones, consequences of hydro technical accidents, dam breaks, floods and forecasts for the purposes of emergency prevention is of topical importance. Complex use of modern computer systems, remote sensing materials and modeling methods allows approaching the predicted model to the real one, taking into account all factors affecting the development process, assessing the scale of consequences and taking preventive measures to prevent accidents in advance. In addition to solving environmental problems, modern remote sensing methods are able to solve a whole range of tasks for mining enterprises, such as the creation and maintenance of databases of cartographic, analytical, situational and managerial information
