Application of both the overfill and renourishment techniques is demon- 

 strated in the following example problems. 



*************** EXAMPLE PROBLEM l*************** 



GIVEN: Composite native beach material phi parameters 



(|)g^ = 2.47(t) (0.18 mm) 



d.,, = 1.41(J) (0.38 mm) 

 Id 



Composite borrow material parameters 



(j)„, = 3.41(|) (0.09 mm) 



6,, = 1.67(t) (0.31 mm) 

 lb 



FIND; 



(a) The fill factor, R^ 



(b) The renourishment factor, Rj 

 SOLUTION: 



(a) Using equation (5-2) 



_ '*'84 + '''16 

 ^(t) " 2 



V " ^'^^ 2 ^'^^ = ^-^^ ^°-2^ ™^ 



and 



^^h = ^'^^ 2 ^'^^ = 2-5^ ^°-^^ "™^ 



Using equation (5-1)
