60 Remus PravalieFig. 1. Vidraru dam lake location (Source: Cadastral Map For RomanianWaters, 1992; Spatial data sets www geo-spatial.org).Along with the dam, the hydroelectric power plant in Cetăţuia or Corbeni-Argeşwas built as the first underground hydroelectric power plant in Romania located toa depth of 104 meters below the Argeş riverbed. It has a total usable power of220 MW.Copyright © Editura Academiei Oamenilor de Știință din România, 2011Watermark Protected
General Considerations Regardingthe Impact of the Vidraru Lake Hydro Facilities on the Environment 61The water passing through the hydroelectric turbines flows into the Oesti Lake,downstream from it [2].The Vidraru Lake, together with the lakes on the bank of the Dâmboviţa River(e.g. Pecineagu, Sătic), is part of the Bucharest water supply system [11].2. Physical-geographical characteristicsIn terms of lithology, the Vidraru Dam is built mostly on crystalline rocks, namelygneiss (the Cozia gneisses), paragneiss, and hard rocks, that are resistant andwater-repellent.By its geographical position, the terrain of the drainage basin of the Vidraru Lakeis characteristic of the high mountain area (Moldoveanu Peak, 8,346 ft., andNegoiu Peak, 6,713 ft.), with a crystalline structure affected by the quaternaryglaciation that left glacial cirques at the top source of those two tributaries, Capraand Buda, harbouring the homonymous glacial lakes [6].The lake basin is mostly based on Loviştea Depression, in its eastern extension,where the heights are below 4,921 ft. (Lăcşor Peak, 4,829 ft., Haţeganu Peak,4,396 ft.), and the lower part is located on the southern alignment of the FăgăraşMassif (Ghiţu Peak, 5,321 ft., in the east, and Frunţi Peak, 5,032 ft., in the west)[10] (fig. 2.).The climate is influenced and determined by the movement of air masses, altitudeand configuration of the terrain, but also by the existence of the Vidraru Lake thatdetermines a topoclimate characterized by moderate temperatures, high humidityand a local air circulation in the form of local mountain – valley winds.The average annual temperature is 6.0 o C, the lowest value being recorded inJanuary (-2.4 o C), and the highest in July (16.1 o C).Thus, the winter months (December, January and February) show temperaturesbelow 0 o C. The average annual depth of precipitation is 770 mm.The average annual wind speed is 0.9 m/s, the highest one being in March(1.2 m/s) and the lowest one in December (0.6 m/s). The number of days withsnow cover is 101, with a maximum in January (27 days), followed by February(24 days), March (17 days) and fewer days in April, November and December,and the largest thickness is recorded in January and February, i.e. 15 to 20 cm[13].The lake-related hydrographic network is represented by two main tributaries:Buda (22.6 km) and Capra (20 km) that interflow in the upper part of the lakewith the top source in the homonymous glacial lakes [8].Other tributaries of the lake are Cumpăna, Valea lui Stan, Oticul, Valea cu Peşti.Copyright © Editura Academiei Oamenilor de Știință din România, 2011Watermark Protected
