Abstract

The aim of this study is to assess and to analyze the seasonal and interannual variability of the low flow indices in the Barlad River catchment area. The low flows and droughts have an important role in the river flow regime because they are significantly connected with the basic water resources. This analyse might provide an efficient management of the resources during the hydrological extremes, as well as an assistance in prevention and risk management strategies. The study is based on the use of the software package LFSTAT that enables the standardized calculation of low flow statistics, in order to provide the low flow indices. The times series of daily discharges at the nine hydrometric stations situated in the Barlad River catchment area for the period 1970-2014 have been used for this analysis. Also, the calculation was made for a hydrological year beginning from December 1st to November 30th. A stream-flow deficit analysis was performed using the threshold level method, where the 70th percentile from the duration curve was used as the threshold level. Based on this analysis of the low flow and drought characteristics, an assessment of the stream-flow deficit in the Barlad River Basin was highlighted.
