Wind and wave regimes of the Kiev pumped-storage station reservoir

Abstract

in the air." This is caused by the fact that the ends of the embedded parts cannot be kept at the design elevation (deviations in the dimensions, welds, spacers, and other factors have an effect)~ If the end of the embedded part is located above the design elevation and is deflected toward the upper pool, then the design point on the axis of the working surface is not accessible for sighting and exact measurement of the distance, i.e., it becomes impossible to set up a beacon.As a consequence of this, during the entire time of assembly an observer is needed at the theodolite, ~ systematically checking the correspondence of the embedded part being assembled to the design angle and distance.As regards the effect of displacements of the dam on the accuracy of assembly, this problem is not completely solved in the described method but is to a considerable extent, since the initial markers are located in the dam, are transferred upward as the dam grows (the higher, the more frequently), and move together with the dam and tracks~ The reservoirs of a pumped-storage station (PSS) operate in a regime of daily regulation of the volumes and levels of the water. WIND ~ND WAVE REGIMES OF THEThis gives rise to certain characteristics (compared with seasonal and carryover reservoirs) of the effect of the wind and wave regime on the dike slopes, as is seen from the experience of operating the reservoir of the Kiev PSS [I, 2].The size of the reservoir in plan is 1450 • 450 m, the length of the dike is 4.7 km, the depth at the normal pool level (NPL) is 8 m and at the dead storage level (DSL) 2 m. The 3.7 million m ~ useful storage is filled with water from the Kiev hydroelectric station reservoir.
