Four altitudes, between 150 m and 250 m, mark the relief of Bacău, being located on most of the locality, on the second terrace 160-165 m. The low meadow terrace is demolished, but it rises in the common area of Bistrita with Siret. Bistrita's major white is predominant in the range of the settlement, through the ponds, constituting a real reservoir for the accumulation of groundwater. The backyard also has an advantage by positioning it in close proximity to the subcarpathian dislocation line. The backyard is located on flat or slightly leaning terraces with an eastern and south-east exhibition, in stabilized slopes, with good drainage and a rich canal. The marshes and terraces nearby are widely used for the cultivation of fruit trees, grapevine and grain.
