GETMU routine to compute mean wave height or wave period based on water level
Routine computes mean wave height based on the relation between
muHsig_t and WL_t as used in Van de Graaff (1984) or using a
combination of a polynomal of degree 2 and degree 1 (above a specified
value of WL_t). Routine is also applicable to compute the mean wave
period; this is only possible by using a combination of a polynomal of
degree 2 and degree 1 (above a specified value of WL_t)
syntax:
mu = getMu(WL_t, Relation)
input:
WL_t = Water level [m] ('Rekenpeil')
Relation = (optional) 2*3 matrix giving the relation between WL_t and mu (either muHsig_t or muTp_t);
The first row should contain the three coefficients of a polynomal of degree 2;
for values of WL_t larger than Relation(2,1), a linear relation
given by Relation(2,2:3) will be used.
If no relation is given, the relation between muHsig_t and WL_t
as used in Van de Graaff (1984) will be applied.
