ancient_1: Estimating sediment flux in ancient rivers.

Description Usage Arguments Value

View source: R/mahon_bedform_relations.r

Description

ancient_1 estimates the sediment flux (qs) of ancient river deposits based on dune cross-stratification, bankfull depth reconstruction, and grain size. Implemented from Mahon et al. (2018). Original relations referenced therein.

Usage

1
ancient_1(Tsm, D50, Hbf, uncert = NULL)

Arguments

Tsm

The mean thickness of cross-bedded cosets. (see publication for more information)

D50

The median bedload grain size. Determined from samples.

Hbf

The mean bankfull flow depth. Determined from preserved barforms.

uncert

The uncertainty window for empirical parameters. The user should put in a confidence interval. A lower confidence interval will have a narrower error envelope, but will require more tenuous conclusion.

Value

Returns a list with elements: S, the river slope (dimensionless). hd, the dune height in the ancient river (m). V, the dune migration rate in the ancient river (m/s). qs, the bedload flux in the ancient river (m^3/s). If uncertainty is also requested, the output will include upper and lower bounds for confidence, V_env and qs_env
