Editing River Afan (section)

==Course==
The Afan rises on the northern slopes of [[Mynydd Llangeinwyr]] to the east of [[Blaengwynfi]], and flows in a generally south-westerly direction roughly parallel to the [[River Neath]] with which it shares its western [[drainage divide|watershed]].

The river passes the [[Afan Forest Park|Afan Argoed Country Park]] in its middle reaches. It converges with the river Pelenna at [[Pontrhydyfen]]. From here it turns southward towards Port Talbot.

To aid the construction of the docks at Port Talbot, the river was impounded and a diversion channel built that now forms the lower reaches of this river. There are two weirs in this final tidal reach of the Afan; Greenpark Weir at the upstream tidal limit, which has been reconstructed in 2017 and provides headwaters for the dock feeder channel that approximately follows the river's original route, and Newbridge Weir, which is the most downstream weir, presents a barrier to fish passage and is in a poor state of repair.

A [[motte and bailey castle]] stood on the banks of the river as it passed through [[Aberavon]] during the [[medieval]] period. No remains are now visible above ground, but the site of the castle is commemorated in local street names.
