RISK PHENOMENA IN THE HYDROGRAPHIC BASIN BIZDIDEL (2000-2007)
O. Murărescu, R. Ţurloiu
ABSTRACT. – Artery Hydrographic Bizdidel is placed in the Sub-Carpathians area in Ialomiţa basin, being tributary of the river Ialomiţa. It falls within the small watershed, by precipitation liquid and solid. Annual regime of fluid leakage is influenced by food sources, the annual average flow rate being around 1 m3/s, with a space-time variability influenced by food sources. On a multiannual basis, since the flow varied during the period examined in our study, between 0.1 m3/s (in 2000) and 240 m3/s (2001). Between the years 2000-2007 there were a number of special events such as water floods, flash floods can be classified as type “arrow”, the flows recorded in the 24-72 h fluctuated between 180-240 m3/s. Hydrographic artery produced flash floods that led to a series of changes in landscape Bizdidel basin and also have been lateral erosion that led to discontinuation in a short period of observations at hydrometric station located before the confluence with the river Ialomita which required the determination of flows through “limnimetric key in red”. In the same context, it appeared to still needing a location upstream hydrometric station in the right side of Bezdead locality, in order to follow developments on this artery hydrographic liquid leakage.
Keywords: Bizdidel, liquid leakage, flood, hydrological risk, 2000-2007.
