Abstract

The dams along with the accumulation lakes formed behind them are man-made water reservoirs for efficient use of the planet's water resources. The dams are big hydrotechnical structures in particular represents construction with very long duration of life and achieve their financial efforts imply particularly important. Over time, changes of external environmental factors may occur, which will influence the behavior of the dam. The environmentally aggressive conditions can be changed in relation to the material from which the construction is performed, natural cataclysms, earthquakes, floods, winds or extraordinary snow can occur. All these changes can influence the strength and stability of the construction, which can lead to the destruction of the building and sometimes to catastrophes.Their monitoring during exploatation represents the guarantee of their safety and prevent accidents that could become catastrophic. One of the best method of monitoring dams is the geodethic measurements. Analysis deformation of vertical and horizontal displacement vector of the dam can give us information regarding dam behavior and it can allow owners to take action early to prevent catastrophic events. This paper analysis the in real displacements vectors during 1973-2019 of the dam of Valea de Pesti, Hunedoara, Romania because of the special characteristics they pose. Valea de Pesti Dam is located on River Valea de pesti, 500 m upstream of its confluence with the Jiul de Vest river. The dam provides a reservoir with a volume of 4 500 000 cubic meters of water supply in order to Lupeni Petrosani area.
