In hydReng: Hydraulic Engineering Tools

Bedload Transport Capacity (Meyer-Peter Müller)

Description

Calculates the bedload transport capacity using the formula by Meyer-Peter Müller. The formula is valid for bed slopes less than 0.005.

Usage

bedload_MPM(dm, J, Rs, B, f_kSt = 0.85, t_crit = 0.047, rho_s = 2650, s = 2.65)

Arguments

dm	Median grain size [m].
J	Bottom slope [-].
Rs	Hydraulic radius [m].
B	Bottom width [m].
f_kSt	Friction factor = (k_StS / k_Str)^(3/2) (default: 0.85).
t_crit	Critical shear stress [-] (default: 0.047).
rho_s	Density of bedload material [kg/m3] (default: 2650).
s	Relative solid density [-] (default: 2.65).

Value

Returns the bedload transport rate [kg/s].
