...Figure 1 Nebraska map showing the Niobrara, North Loup, and Calamus rivers. The localities where samples were taken on each river—Taylor, NE (“T”, North Loup River), Niobrara State Park (“NSP”, Niobrara River), and Burwell, NE (“B”, Calamus River)—are indicated by small boxes. A) Aerial...

... the Calamus and Mississippi Rivers. Furthermore, it is well known that dune height can be related approximately to formative flow depth. Although prediction of flow depth from cross-set thickness and dune height is imprecise, it provides a useful complement to other methods of estimating flow depth from...

This dataset includes measurements of particle diameter and flow depth from the North Loup, Niobrara, and Calamus rivers in Nebraska, U.S.A. ( Fig. 2 ). The data contain 28 sediment...

... style, which can be tested by examining channel patterns over the larger area of the exposure, which will be the focus of our future studies. The most prominent facies Sf in this study are mostly found in modern low-sinuosity and braided systems. The Calamus river (Nebraska) is an analog of a low...

... for the calamus; a portion of the upper right vane came off during excavation and was not recovered. The rachis is mostly pyritized, with some portions still having a black, apparently carbonized film covering, possibly the cortex. The vanes on the pennaceous portion of the feather have a closed-pennaceous...

... ). Inclined bar-accretion surfaces show apparent northward dips in 29 instances and apparent southward dips in three instances, in accord with the predominantly downstream dip of accretion surfaces in many GPR profiles of sandbed rivers (e.g., Calamus River: Bridge et al. 1998 ). Where trough cross-sets can...

Thick multistoried complex from other parts of the Siwalik basin (Swie-Djin and Hussain, 1981; Behrensmeyer and Tauxe, 1982 and Johnson et al. 1983) have also been interpreted as deposits of large-scale braided river systems with rapid avulsion...
