Bedload Transport Capacity (Smart and Jaeggi)
Description
Calculates the bedload transport capacity based on the formula by Smart and Jaeggi (1983). This formula is recommended for slopes between 0.005 and 0.2.
Usage
bedload_SJ(d30, dm, d90, J, Rs, um, B, t_crit = 0.05, rho_s = 2650,
s_value = 2.65)
Arguments
d30 |
Grain size distribution parameter [m]. |
dm |
Median grain size [m]. |
d90 |
Grain size distribution parameter [m]. |
J |
Bottom slope [-]. |
Rs |
Hydraulic radius [m]. |
um |
Mean flow velocity [m/s]. |
B |
Bottom width [m]. |
t_crit |
Critical shear stress [-] (default: 0.05). |
rho_s |
Density of bedload material [kg/m3] (default: 2650). |
s_value |
Relative solid density [-] (default: 2.65). |
Value
bedload_SJ returns the bedload transport rate [kg/s]
