Description
The article considers the mathematical task of calculating the transient flow of water in the regulation of concentrated releases of water discharges on stream flows in lower tails of spillway waterworks. An algorithm, analytical solutions based on hydraulic calculations of the process of propagation and transformation of long waves described by Saint-Venant equations are constituted. These equations are nonlinear and have no exact solutions. To obtain approximate solutions these equations are linearized. The efficiency of spillways depends on how accurately hydraulic processes characteristics are measured. Control and direct measurement of characteristics of hydraulic processes in natural conditions is difficult, which requires applying methods of mathematical modeling and simulation studies of transient processes, which are based on the algorithms of functioning of transient hydraulic processes control. Introduction of the developed method for hydraulic calculation of discharge releases to streams, diverting the water from water discharge structures, allows optimize idle and non-technological discharges of water from reservoirs. Considering the highly dynamic nature of the water flow in the lower tails of the dams at concentrated releases of water discharges from reservoirs, development of new methods of hydraulic calculation of extreme discharges and water depths at the critical sections of watercourses with transient regime of water flow is an important task

SEISM SAFETY OF PRESSURE HEAD HYDRAULIC ENGINEERING CONSTRUCTIONS
DescriptionExperience of supervision of safety of the hydraulic engineering constructions, operating in our country since 1971, and the first 15 years of the Federal law of the Russian Federation No. 117-FZ from 21.07.1997 “About safety of hydraulic engineering constructions”, when persons under surveillance of GTS steel of power, the industry and a water economic complex is given. The majority (97 %) potentially dangerous GTS of the Russian Federation treat the IV class of solidity with service life from 40 to 50 and more years where, as a rule, is absent or the operation service, insufficient quantity of instrumentation is small. Monitoring of a technical condition of similar GTS is possible with use of the mobile, mobile complexes equipped with the modern equipment (hydrological, geophysical, geodetic, mechanical, etc.). Safety of GTS is in many respects caused by a skill level of the operational personnel. For the solution of questions of increase of their safety amending the current legislation is necessary
