n_bathurst1985

<code>n_bathurst1985</code> calculate Manning's n using the Bathurst (1985) method
for estimating grain roughness

Estimates frictional constants for hydraulic analysis
of rivers. This HYDRaulic ROughness CALculator (HYDROCAL) was previously
developed as a spreadsheet tool and accompanying documentation by McKay and
Fischenich (2011, <https://erdc-library.erdc.dren.mil/jspui/bitstream/11681/2034/1/CHETN-VII-11.pdf>).
