HYDROLOGICAL MODELING OF THE TAZLAU RIVER BASIN USING MODERN TECHNOLOGIES

The manifestation of hydrological events, sometimes catastrophic, recorded over the years in the Tazlu hydrographic basin with particular damages from an economic point of view and loss of human life imposes the need to know as deeply as possible its characteristics and especially its reaction to different amounts of precipitation for a management with a preventive role.This study has as its main objective the simulation of different scenarios of hydrological events based on which to develop large water management strategies.For the Tazlu hydrographic basin, the model calibration was carried out on the event recorded in the period 11-14 July 2005 (Qmax of 1556 mc/s on 13.07.2005 at 00:00 at the Helegiu hydrometric station), and the validation was done on the event recorded in the period 02.06-05.062016 (Qmax of 1418 mc/s on 03.06.2016 at 00:00 at the Helegiu hydrometric station).As inputs, in addition to the data series recorded on rainfall and flow, a numerical land model with a resolution of 5 m and the Corine Land Cover and Soil database from 2018 were used, and the Loss-SCS-CN method was chosen as the method.
