Bedload transport fomula

Hi

I am using Wilcock & Crowe and it seems it highly underestimates the bedload transport in my reach. Our manual calculations done with the Recking formula (2013,2016) seem to be more accurate, but unfortunately the Recking formula is not available (yet?) in Basement.
I'm still testing if other formulas would work better, but from a first view it seems Wilcock and Crowe was the closest.
I'm working in a gravel bed river with multi-grain 1D simulations.

I also tried to work with the bedload factor (e.g. 25 or 100) but then I get aggradation at the upstream boundary which after some years becomes so large the banks overflow.

If anyone has any ideas how I could improve this, I highly appreciate any advice!

Thanks

Alyssa

Re: Bedload transport fomula

Hi Alyssa,

you might try and calibrate a mpm-like formula (by changing the exponent and the pre-factor) with your data!
