RESEARCH ON BEHAVIOR OF TORRENTIAL CORRECTION WORKS IN THE ANIEȘ HYDROGRAPHIC BASIN
Abstract
In Anieș basin, first torrential correction works were carried out in 1988, on Butucilor Stream, with waiver of narrow gauge forest railways and open forest road Anieș. This work consisted of two thresholds in performance with a height of 2 meters, connected together by trapezoidal drains and the upstream side of a dam with a height of 6 feet with 2 drain holes that could close using metal gates. The works were made ​​of stone masonry with cement mortar. In the next phase, the years 1988-1997 were executed torrential correction works upstream the Butucilor Stream, on the streams Deluțului, Brazilor and Lupilor, consisting of a dam with a height of 3 meters and a channel connection. These works were well behaved, but after repeated floods in the basin, silt transported have exhausted retention capacity and currently works cross some channels are clogged drain, sometimes being destroyed masonry, is even installing vegetation on the shoulders dams. Currently, due to dynamic torrential processes, torrential correction action on Anieș basin, continuous, Mihăiasa Valley is a complex process of restoration and is running a number of 5 dams with heights between 2 and 3.5 meters, from which 2 filterable, 6 thresholds and 9 sleepers.
