风力产生的波浪影响阿拉斯加中东部的育空地区河的迁移。在阿拉斯加-加拿大边界下游125英里处的圆环，育空地区河进入育空地区平原的东端，这是一个20-75英里宽，近200英里长的冲积盆地。平地包括一个低地，其中包括育空地区山谷和下游支流山谷。从北部流入的支流有豪猪河、辛杰克河、克里斯蒂安河、霍扎纳河、哈德温齐茨河和达尔河。从南面进入的是桦树溪和海狸溪。在史蒂文斯下面七英里处，河流通过一个狭窄的峡谷离开平原。从环形到育空地区堡，育空地区的河道是N 450 W，它是复杂的编织。从育空地区堡到比弗下游的一个点，河流改道至S 750 W，流入一条宽阔的主河道，从主河道中弓形脱落分支并重新进入。沿着北岸，河道被众多的大西洋豪猪河的支流所复杂化。在史蒂文斯附近，育空地区被限制在一条宽阔的水道中，该水道在当地分支成多达三到四条较小的水道。
Wind-generated waves influence the migration of the Yukon River in east-central Alaska. At Circle, 125 miles downstream from the Alaska-Canada boundary, the Yukon River enters the eastern end of the Yukon Flats, an alluvial basin 20-75 miles wide and nearly 200 miles long. The Flats comprise a lowland that includes the Yukon Valley and lower p. arts of tributary valleys. Tributaries entering from the north are Porcupine, Sheenjek, Christian, Chandalar, Hodzana, Hadweenzic, and Dall rivers. Those entering from the south are Birch and Beaver creeks. Seven miles below Stevens, the river leaves the Flats through a narrow canyon.From Circle to Fort Yukon the course of the Yukon is N 450 W and it is complexly braided. From Fort Yukon to a point downstream from Beaver the river changes its course to S 750 W and flows in a wide main channel, from which bow-shaped sloughs branch and re-enter. Along the north bank the channel is complicated by numerous distributaries of the Chand-alar afid Porcupine-rivers. Near Stevens the Yukon is confined to one broad watercourse that locally branches into as many as three or four smaller channels.
