This script gets the longshore sediment transport, using the CERC, Bayram et al. and Kamphuis equations. Different K values are used with the CERC equation.
All the input parameters are given, using the command window.
rho = mass density of water, kg/m3
rhos = mass density of sediment, kg/m3
poro = sediment porosity, dimensionless
hb = wave height at breaking, m
db = water depth at the breaking line, m
tetab = wave breaker angle relative to the beach, deg
wf = sediment fall velocity, m/s
mb = slope beach, dimensionless
d50 = median grain size, m
T = wave period, s
cf = friction coefficient, dimensionless
A = shape parameter m1/3,
tim = time in which you can evaluate the LST, hrs
The results are shown on the table in the command window.
It is only necessary to run the function.
