The sediment movement on a river plays a crucial role in safe navigation and economic activities on navigable channels. Environmental changes in time are given by the morphological characteristics of the riverbed during seasonal water variation on the Danube River. This study presents a comprehensive assessment of the Danube River's velocity and current characteristics based on Acoustic Doppler Current Profiler measurements. The correlation between flow velocities and depths helps to understand the factors that influence sediment patterns and provides insights into the sustainable management of the river system. The study was conducted along a 71-kilometer length of the Sulina Branch from the Danube River, where ADCP measurements were collected at multiple locations and over periods. The data collected included water depth, flow velocity, and current direction. By clustering the column depth cell velocities it revealed significant spatial and temporal variations in the velocity and current patterns, influenced by factors such as river morphology, discharge, and seasonal changes.
