THE DEBITS STUDY OF TĂRCĂIŢA VALLEY IN ORDER OF HYDROENERGETICAL VALORIFICATION PUBLISHEDCălin Ioan Iovan, Călin Gheorghe Păşcuţ
Measuring debits of a water course is the first step in a broader study of their profitable purposes in various ways, in this case is an energy valorification. This study is based on measurements made in 2008 and 2009, the results give a clear picture of the debits variation of Tărcaia Valley in the summer, when they are severely affected by drought, but if this valley is not about a significant variation. The study was realised on the watercourse Tărcaia Valley located on the north-eastern side Codru-Moma Mountains on the hydrological basin's Crişul Negru river and is based on measuring debits in three sections of the surface float method used in determining current and water and measuring method using hydrometric ratchet. Water is being held in a mountain area, hydroenergetical valorification can bring many benefits, in the sense that the production of a certain quantity of electricity can perform various productive activities (animal breeding, trout, woodworking, etc.) or unproductive (agritourism or supply isolated villages). Energy that can be produced this way is a renewable and clean, so should be viewed with the current focus on reducing fossil fuels and the increasingly intense attempts to reduce pollution from their use. Considering measurement errors that can occur for debits determined on each section of the watercourse have been identified as the minimum to avoid other errors in the calculation of powers available and because of this in certain areas of karst structures that can cause large variations of this debits (through underground infiltrations). General trend of variation of debits is a slight decrease. The work was carried out with the wish to present one of many alternative energy generation using natural resources (water) in mountain areas through a method that is without environmental damage.
