Section III may therefore be taken directly as an illustration of 

 the computational aspects involved in the determination of the 

 reflection coefficient of the seaward slope, R . 



Thus, with the detailed computational aspects given in Section III 

 the computations corresponding to the incident wave amplitudes reported 

 by Sollitt and Cross (1972, App. G) are summarized in Table 6.

As found in Section III the important parameters are:

(166) 



and the best estimate of the reflection coefficient, Rtt, is obtained 

 by multiplying the predicted value, R , by the correction factor 0.89 

 associated with the steep slope, tanS = 1/1.5.
