Description paleohydror functions
This package offers several functions and routines for deriving estimates of paleohydrology from field observations of rock outcrops. Data such as grain size are important too.
The functions here make up a mix of tools to calculate and estimate modern suficial processes and back-calculate those processes in ancient rivers.
settle
calculates the settling velocity of particles following the formulation by Dietrich (1982).
lynds_one
estimates ancient river slope using the first method described by Lynds et al. (2014)
lynds_two
estimates ancient river slope using the second method described by Lynds et al. (2014)
lynds_three
estimates ancient river slope using the third method described by Lynds et al. (2014)
xset2H
estimates ancient river dune heights based on cross-set thicknesses. Methods from Leclair and Paola.
H2h
estimates ancient river depths based on dune heights. Methods from Bradley and Venditti.
xset2depthSimple
estimates ancient river depths directly from cross-set thicknesses using the simplest assumptions. Methods from Leclair, Paola, and Bradley and Venditti.
azStringConvert
Azimuth conversion for 'quadrant' based strike/trend measurements.
ancient_1
Estimating sediment flux in ancient rivers following Mahon + McElroy (2018).
modern_1
Estimating sediment flux in modern rivers if bedform height is known following Mahon + McElroy (2018).
modern_2
Estimating sediment flux in modern rivers if bedform length is known following Mahon + McElroy (2018).
bedform_velocity
Estimating bedform migration rate as a function of reach-averaged slope.
bedform_bedload
Estimating bedload as a function of bedform height and migration rate. After Simons et al. (1965)
height_length
Estimating bedform height if bedform length is known.
trampush_slp
estimates paleoslope using an empirical relationship with median bedload grain size and bankfull flow depth from Trampush (2014).
