RESEARCH REGARDING WITH HYDROLOGICAL REGIME OF TORRENT FLOODS AT STREIULUI UPPER WATERSHED

摘要

The hydrological characteristically regime to pouring freshet from any watershed is in interrelation with precipitation regime. The dimensions which present a characteristic importance for the hydrological regime to pouring freshet are: the high of maximum precipitation batch in 24 hour; the pouring rains with these parameters: the quantity of fallen precipitation, the duration, intensity and frequency, all correlated with spreading area in studied territory, distribution in the course of year and the force of pouring freshet resulted; the annual average number of pouring rains attend to resulted pouring. The hydrological pouring freshet regime was studied in the classical conditions: in case of transformed torrential watersheds trough hydro-technical executed works on these thread. It was observed immediately after the hydro technical works executed transverse, the value of maximum capacity it was reduced to 50-70 %, while the duration of trickling is reduced to 40-60 %. The hydrographs form is upset according to the abstention of a remarkable pouring upstream of works.
