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 review article presents the main results of the activity of JSC TC “Tatmelioratsiya” and “Tatmeliovodkhoz” administration on the land-reclamation work in the Republic of Tatarstan. These works included the repair, reconstruction of dams and ponds, the restoration and construction of new irrigation systems, commissioning and start-up of new fuel-efficient sprinklers. At January 1, 2011 a complete inventory of the technical condition of existing hydraulic structures was carried out by the JSC TC “Tatmelioratsiya”. There are 298 waterworks, that require repair and reconstruction in the Republic of Tatarstan. At the same time, it should be noted, because of the intensive use of constructed facilities at different time of natural disasters, the 52 dams was partially destroyed and require urgent measures to restore them. Among the emergency, the greatest danger in case of emergencies during the flood were 18 waterworks, where in case of emergency there is a real threat of flooding populated areas and economic facilities located in the flooded areas. The government of the Republic had provided funding for the anti-flood measures in 2011 in the amount of 40 million rubles, moreover, a republican target program for 2012- 2014 on the repair and reconstruction of hydraulic structures for the prolongation until 2017 was developed and adopted. The programs, passed by the Russian government and the Republic of Tatarstan, allow to strength food security and reduce import substitution of basic foods that will eventually contribute to the development of their own agricultural sector.

Системы обеспечивают регистрацию сейсмических событий интенсивностью выше двух баллов по шкале MSK64 на плотине и плановопериодическую регистрацию микросейсмических колебаний плотины в режиме штатной эксплуатации оборудования. The purpose of this study is to create information system for seismometric monitoring of the technical condition of hydroelectric dams. To achieve this, the authors of the article used modern methods and principles for designing software and technical systems. The methodological basis of this system is the engineeringseismometric method. The registered vibrations determine the dynamic and elastic characteristics of the structure. Analyzing their variations and taking into account the influence of factors of external influences, it is possible to estimate the technical condition of the structure. The authors provide a survey of seismometric monitoring systems for buildings and structures, defined main technical and functional requirements, which a monitoring system should provide. A model and a structure of the information system for seismometric monitoring of hydroelectric dams were developed using structural analysis technique. The paper describes the processes of collecting, processing, storing and analyzing data for seismic events recording and monitoring the technical condition. Based on the system model and the technology for seismometric monitoring data, automated systems for seismometric monitoring for the dams of Krasnoyarsk and Zeya hydroelectric stations were developed and put into operation. The systems provide registration of seismic events with an intensity of more than 2 points on the MSK64 scale on the dam and scheduled periodic recording of microseismic dam oscillations in the normal operation of equipment for monitoring the technical condition.

The main method of steel hull protection from corrosion is sacrificial protection. Today the performance assessment of the sacrificial protection is difficult and laborious problem which demands substantial costs and application of job-dedicated machinery. In the article the possibility of the exception of expensive visual inspection to control cathodic protection systems of steel hulls is proved. It allows reducing the complexity of control and the costs of its implementation. Measurements the potential of the ship's hull and the strength of protection current running on a reference electrode in six control points have been carried out to determine the technical condition of cathodic protection systems in the studied vessels. Measurements of control parameters were performed three times; precision of measurements is confirmed by mathematical and statistical methods.
