In considered article the results are presented of the carried out researches on high-mountainous lakes of the Tashkent area. Visual inspection of a modern condition of natural dams of considered high-mountainous lakes of the Tashkent oblast is carried out. On the basis of the analysis of visual inspection it is possible to note, that the common technical condition of natural dams of the submitted high-mountainous lakes safe and does not represent danger to downstream situated territories. It was carried out the modeling of occurrence of emergency situation on high-mountainous lakes of the Tashkent oblast in case of full or partial destruction of natural dams. By an available calculation method of flooding waves are determined its key parameters, height of a wave, speed of distribution of a wave of break on the certain distances and reaching time the given wave up to the certain distances. On the basis of calculation method have been calculated and put on cross-sections of the rivers Pskem and Kocy zones of possible flooding in full and partial destruction of dams of high-mountainous lakes. Results of the carried out calculations have been put on the digital map, created on platform ArcView 3.2a.

The aim of the work is to develop theoretical and methodological foundations for predicting the likelihood of fires in the premises of hydroelectric power plants, as well as compiling algorithms for monitoring the fire safety system, the “Serviceability control” technological process and the “Fire” technological process. In the course of the work, theoretical studies of methods for assessing the safety of power generating enterprises in the “man -machine -environment” system and ways of occurrence of emergency situations at power plants were carried out. The analysis of methods for assessing the safety of power plants in the “man -machine -environment” system is considered and the analysis of the ways of occurrence of emergency situations at power plants, as well as the types of fires and the peculiarities of their detection in the premises of the hydroelectric power plant. And an attempt is made to solve the problem of super-early detection of fires and fires in the system under consideration. The theoretical and methodological foundations for predicting the probability of fires depending on the operating modes of systems, devices and equipment and a compiled model of a fire hazard monitoring system are given.
