horisontaalne või subhorisontaalne pind oru veerul, mida jõe poolt piirab astang, mille kõrgus sõltub konkreetsetest tingimustest, elongated, relatively level stripe of land on the side of a valley that is separated from the flood plain or other terrace by an escarpment. Fluvial terraces are the remnants of earlier floodplains and have formed due to the graduated downcutting of rivers while lower landforms are gradually younger. Fluvial terraces can appear on both slopes of the valley but not necessarily. Due to their geological setting terraces can be devided as alluvial or accumulative terraces, erosional terraces and core or kernel terraces.
