Flume experiments on the alignment of transverse, oblique, and longitudinal dunes in directionally varying flows Flume experiments on the alignment of transverse, oblique, and longitudinal dunes in directionally varying flows
For more than a century geologists have wondered why some bedforms are orientated roughly transverse to flow, whereas others are parallel or oblique to flow. This problem of bedform alignment was studied experimentally using subaqueous dunes on a 3–6-m-diameter sand-covered turntable on the floor of a 4-m-wide flume. In each experiment, two flow directions (relative to the bed) were...

Origin, structure, and evolution of a reattachment bar, Colorado River, Grand Canyon, Arizona Origin, structure, and evolution of a reattachment bar, Colorado River, Grand Canyon, Arizona
In a channel expansion, flow can separate from the bank, creating a zone of relatively weak recirculating current. Bars that accumulate in this weak flow near the point where flow reattaches to the bank are called reattachment bars. As a reattachment bar evolves, the recirculation zone may fill with sediment and restrict flow from the main channel. The increasingly restricted flow over...

Field guide to sedimentary structures in the Navajo and Entrada sandstones in southern Utah and northern Arizona Field guide to sedimentary structures in the Navajo and Entrada sandstones in southern Utah and northern Arizona
This field-trip guide describes the common sedimentary structures that occur in eolian sands. The outcrops that are described occur in the Navajo and Entrada Sandstones between the areas of Page, Arizona and St. George, Utah (figure I), but the sedimentary structures of these two sandstones are typical of most eolian deposits. The main part of the guide discusses the geologic setting and...
