Multiple choice

For a rectangular channel section, Group I lists geometrical elements and Group II gives proportions for hydraulically efficient section.

   
Group I Group II
       
P Top width 1 $\dfrac{y_e}{2}$
Q Perimeter 2 $y_e$
R Hydraulic Radius 3 $2y_e$
S Hydraulic Depth 4 $4y_e$

ye is the follow depth corresponding to hydraulically efficient section. The correct match of Group I with Group II is

  1. P - 2, Q - 4, R - 1, S - 3

  2. P - 3, Q - 1, R - 4, S - 2

  3. P - 3, Q - 4, R - 1, S - 2

  4. P - 3, Q - 4, R - 2, S - 1
