Features of Operation of Potable Water Supply Reservoirs
Unified results of the inspection of the technical state of 14 potable water supply reservoirs in Moscow after the prolonged period of operation are presented. The main causes of damages of reservoirs' enclosing and bearing structures (force impact, corrosion processes) are analyzed. The design defects causing the accumulation of damages in structures elements are revealed. A complex of measures aimed at the improvement of steadiness of facilities and reduction of expenditures for their maintenance is proposed.
Key words: reservoirs, potable water, ground water, corrosion, drainage, deformation, air-tightness.

Calculation of Module of Maximum Flow of Unexplored Rivers' Rainfall Floods
A dependence required for the evaluation of values of mo dules of maximum rainfall flow of unexplored rivers on the basis of available materials of observations of flow formation characteristics is presented. The examination of the dependence obtained for some regions makes it possible to recommend it for calculations in the case of lack of hydrometric observations.
Key words: rainfall flood, module of maximum rainfall flow, intensity of precipitation, evaporation, evaporability.
