courses, which deepens existing landforms such as meanders [2m]. Although rejuvenated rivers maintain a winding course, their meanders are deepened by cutting into the old floodplains floor. These are referred to as incised meanders [2m]. Features of river rejuvenation can be found in the paired terraces of the River Nore, Co. Kilkenny [2m]. Incised meanders can be found in the River Moy [2m].
