Marine water fish farms

Problem

1. Compute the optimum height of a main dyke for a coastal pond site located in a flood free zone. The site is 1 m above zero datum, height of highest astronomical tide above the zero datum being 3 m. Assume medium soil for the give site.

Elevation of ground surface with respect to zero datum
H_g = 1m
Highest astronomical tide above the zero datum H_t = 3 m
Allowance to be given for flood = f_a = o
For given soil condition %S = 15
Assume minimum free board of 60 cm , f_b= 0.6m
