Abstract
The problem of prevention and elimination of emergencies remains very urgent. The prediction of area flooding as a result of seasonal floods, or due to emergency situations is important and is solved on the basis of various technologies. Computer modeling methods based on direct hydrodynamic calculations of surface water dynamics seem to be an effective direction. Of particular interest is modeling the dynamics of filling of hydraulic structures in mountainous terrain. In this article, features of destruction of hydraulic structures in emergency situations on water bodies. The article also mentions the methods of monitoring water levels in the reservoirs. A description of flood monitoring technology is given, the results of its practical use in some regions are discussed, and directions for further development are outlined. This information is subsequently used to predict the emergency situation.
