Small hydroelectric power generation is attractive from both an environmental and economic point of view. Technological innovations mitigation measures are making small plants inexpensive viable source renewable energy which can be generated independently. They contribute not only to protection, but also reduce human dependence on fossil fuels. This study dedicated finding solutions based techn...

The paper presents the results of field measurements and numerical modeling influence various factors on formation coherent structures in confluence zone Sylva Chusovaya rivers, which are dammed by Kamskaya Hydroelectric Power Station (HPS). A characteristic feature measured parameters under study is that they experience both seasonal fluctuations much higher frequency associated with intraday ...

Abstract The aim of the work is to develop theoretical and methodological foundations for predicting likelihood fires in premises hydroelectric power plants, as well compiling algorithms monitoring fire safety system, “Serviceability control” technological process “Fire” process. In course work, studies methods assessing generating enterprises “man -machine -environment” system ways occurrence ...

In the summer of 2021, full-scale studies river level regime were carried out on Volga River section in lower reaches Nizhny Novgorod hydroelectric power station. For this purpose, six temporary water measuring posts equipped throughout site, according to which levels measured during daylight hours. According results study, main characteristics release wave formed daily regulation runoff at sta...

The use of hydroelectric pump-storage system at large scale, MW-size systems, is already widespread around the world. Designed for large scale applications, pump-storage station can be scaled-down for small, remote residential applications. Given the cost and complexity associated with installing a substation further than 100 miles from the main transmission lines, a remote, independent and sel...

The construction of dams usually changes the composition of the fauna within their areas of influence. In the area where the Rosal hydroelectric power station has been installed, in the States of Espírito Santo and Rio de Janeiro, changes to the abundance of anophelinae, planorbidae and phlebotominae were evaluated before (1998-2000) and after (2000-2005) the damming. Nine sample collection poi...

A cusp catastrophe model is developed for slip-buckling slope by catastrophe theory, and the formulations of the necessary and su1⁄2cient conditions for instability of the slope are presented. It is found that di ̈erent regions (II, III and IV in Fig. 4) in the control space divided by the bifurcation set correspond well to the primary, secondary and tertiary creep phases. The corresponding disc...

The present work studied the prevalence and histopathology of Neoechinorhynchus curemai Noronha, 1973 (Acanthocephala; Neoechinorhynchidae) from curimbatá, Prochilodus lineatus Valenciennes, 1836. Eighteen fishes with averages of 46.7 +/- 1.1 cm length and 1,674.8 +/- 75.6 g weight were collected with net, bimonthly from December 1995 thru December 1996 in the hydroelectric power station of Vol...
