Abstract
Quantitative Interpretation of Sedimentary Structures Formed by River Dunes
Suzanne F. Leclair, John S. Bridge
ABSTRACT
New experimental data
from
a range of flumes and rivers have been used to test and develop a theoretical model for the thickness of sets of cross strata formed by the
migration
of subaqueous dunes. The distribution of dune height can be calculated directly
from
the distribution of cross-set thickness, and vice versa, independently of aggradation rate. Mean dune height is approximately 2.9 (± 0.7)
mean cross-set thickness. The new models relating dune height to cross-set thickness have been tested successfully with data
from
flumes and
from
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
sedimentary information.
