In this work, the authors present a technology for riverside terrain model building that has been tested on a number of scientific projects to study the littoral area of tail race of the Irkutsk Hydroelectric Power Station and the Bratsk Reservoir. This model is used for forecasting changes in the reservoir shorelines associated with wastewater in the cascade of hydroelectric power stations. The technology described in the work was approved to solve a number of practical problems and showed its effectiveness. Specialized application software was developed and terrain data from various sources were used to specify and detail the end result.

In the year of Cheboksary hydroelectric power station’s anniversary, the authors of the article aim to investigate the issue of the waterworks facility’s formation in the early 40s of the last century. Based on the principles of historicism and objective analysis, the main stages of implementing the HPP construction plan are considered. The article presents archival documents which examine the problems of decision-making on the construction of the object. The issue of constructing hydroelectric power stations on the Volga, in particular in the territory of Chuvashia, was studied in the specially created Bureau «The Great Volga». Simultaneously with the construction of Cheboksary HPP, the construction of two more stations – Yaroslav­skaya and Balakhninskaya – was considered. The authors present comparative characteristics of the objects. Cheboksary hydroelectric power plant in terms of its performance significantly exceeded other structures. The article notes that prior to the construction of the station, a lot of preparatory and survey work was carried out, which was limited by a tight deadline. As a result of examining the scope of work, material resources and labor costs, the construction of the station was postponed to a later date. Scientists and engineers recognized the priority need to build less powerful stations. The materials of the article can be used for further research of this topic, as well as when writing regional natural history works.

ABSTRACT Cerrado is the second largest biome in Brazil and is classified as a biodiversity hotspot. The establishment of hydroelectric power stations in Brazil originated degraded areas due to the removal of soil for construction of dams, in which native vegetation sometimes fails to reestablish due to the bad soil conditions. Sheep excrete most of the nutrients they ingest, such as phosphorus, calcium, potassium and nitrogen. This study aimed at investigating whether sheep dung contributes to the improvement of soil quality and stimulates the process of ecological succession in areas affected by the construction of the hydroelectric power station of Ilha Solteira. Four areas were selected, located at the Experimental Farm of Unesp Ilha Solteira/SP, and ten plots of 1 m2 each were established. From October 2014 to December 2015, five replicates received 150 g fresh sheep dung every 15 days. In December 2015 soil sample from top 0.10 m was collected for the determination of soil attributes. Aboveground biomass was also collected, separated into four functional groups, oven-dried and weighed. Data were analysed to check the effect of dung addition upon soil and vegetation variables. Dung addition stimulated the development of several functional groups and changed soil nutrient concentrations in all four studied areas.

The article discusses the features of the linguistic expression of the concept of a hydroelectric power station (HPS). The material for the study is the data of etymological and encyclopedic dictionaries, special educational literature, as well as data obtained during interviews of workers of various Russian hydroelectric power stations, and data from a linguistic experiment. The process of research revealed and described: etymology of the name of the concept; conceptual features of the concept; figurative layer (through the analysis of metaphorical names); evaluation layer of the concept. It has been established that the concept of hydroelectric power station (HPS) refers to gestalt concepts, since it is a conceptual system that combines different types of concepts. The professional linguistic picture of the world of hydropower is characterized by the conceptualization of the conceptual categories of «living – nonliving», «simple – complex», «natural – man-made». The axiological layer of the professional concept is poorly expressed against the background of the conceptual and figurative layers.

Labudovo okno locality (50 m-84 m elevation) is situated in the south-eastern part of the edge of the Pannonian Plains, resting along the left bank of the Danube between 1982 km and 1078 km. The investigated locality is the result of rise of the Danube level after dam building of the hydroelectric power station Djerdap I. The vegetation comprises aquatic associations of the classes Hydrochari-Lemnetea Oberd. 1967 and Potametea Tx. et Prsg. 1942. The class Hydrochari-Lemnetea Oberd. 1967 includes the following phytocoenoses: Lemno-Spirodeletum W. Koch 1954, Salvinio-Spirodeletum polyrrhizae Slavnic 1956, Lemno minoris-Azolletum filiculoides Br.-Bl. 1952, Ceratophylletum demersi (So? 27) Hild 1956. The class Potametea Tx. et Prsg. 1942 includes the associations Myriophyllo-Potametum So? 1934, Nympaeetum albo-luteae Nowinski 1928, Trapetum natantis M?lleret G?rs 1960.

The article tells the story of the creation of the Nizhne-Tulomskaya hydroelectric power station (HPP). The main energy parameters of the hydroelectric power station, the layoutof the main structures of the station, and archival photos of the construction time are given. Data on the production and consumption of electricity for own needs, the cost of 1 kW·h during the great Patriotic war are shown. It is told about the reconstruction and current state of the station.
