3. Sédiment Transport
59
By substituting for Ii in CERC équation, we can get
(Ps - P)ga'Pl‘
(3.31)
In the above équation, if “K” taken as 0.39 or 0.4 — Then it is CERC
method and we need to use Hs, whereas, if “Æ” taken as 0.77 — Then it is
KOMAR method, were we need to use Hrms. The estimation of sédiment
transport in the above formula dépends on wave height and direction only.
Field measurements of Q and Pis are plotted in Fig. 3.14. Figure 3.15 gives
lines of constant Q based on Eq. (3.31). [For details refer US Army Corps
of Engineers, CEM 2002.]
