Abstract

Pucioasa Lake, located upstream from the town of that name, was put into operation in 1975. The initial volume was 10.764 million m3, but the main problem is alluvial intense because most retain strong flow Ialomiţa brought this river and its tributaries. This led to an intense clogging with reduced volume of water retained, so that in 2006 the amount calculated at a height of 418 m was of 6.47 million m3, with a sink situation after floods in 2005 washed relatively and 2006, generated escape maneuvers. After the years 2007 and 2008 when there were no floods, so no washing, only massive deposition, in 2009 the volume of water at 418 I was 3.59 million m3, resulting in clogging of approx. 63% of original volume. Causes of clogging situation are: changing the slope of the upstream rivers, raising river erosion, location downstream of the confluence with Ialomicioara Laotei with basin developed largely deforested in the Carpathian foothills, made up of easily eroded materials.
