The River Mellte is a river in south Wales. It is formed by the confluence of the Afon Llia and the Afon Dringarth. It then flows south through the village of Ystradfellte to Pontneddfechan where it joins with the Nedd Fechan to become the River Neath.

The Nedd Fechan is a river almost wholly within the county of Powys, Wales, currently administered as part of the unitary authority of Powys. It rises on the eastern slopes of Fan Gyhirych in the Fforest Fawr section of the Brecon Beacons National Park and flows south for 7 miles (12 km) to join with the Afon Mellte at Pontneddfechan, their combined waters continuing as the River Neath to the sea near Swansea. The only significant tributary of the Nedd Fechan is the Afon Pyrddin which joins it at Pwll Du ar Byrddin. Downstream of this confluence it forms the boundary between Powys to its east and Neath Port Talbot to its west.

The Tanat Valley is a large valley in northern Powys, Wales, formed by the course of the Afon Tanat and its tributaries. Situated south of the Berwyn range, the valley forms from at Llangynog from the merger of two narrow valleys, the Cwm Pennant and Cwm Rhiwarth. Various historic sites, including the Iron Age hillfort Llwyn Bryn-Dinas and the medieval St Melangell's Church are located along the valley. Largely agrarian, sheep farming has formed a major industry in the region for several centuries. Large-scale slate and lead mining in the region lasted from the 16th to late 20th century, although earlier mines possibly existed during the Iron Age.
