I have a question related to the formula 11.108 (page 359 of Flow Manual version 3.15 rev:18392).<br /><br />This formula will define the coefficient for shallow or deep waters coefficient for Bijker formula. My questions is:<br /> <br />Following the b equation (11.108) it seems to be the other way around (BD should be BS and BS should be BD). I did some calculations and using the equation provided it leads to the opposite interpretation (5 for deep water and 2 for shallow water). I tried to change the BD for BS and seems to be ok (maybe a misswriting): smoothly changing from 2 (deep water) to 5 (shallow water). Am I right or I'm missing something?<br /> <br />Thank you in advance,Guilherme Silva2015-06-23T08:53:11Z
