Question

The type of flood routing (Group I) and the equation(s) used for the purpose (Group II) are given below.
$\begin{array}{cccc}& \text{Group I}& & \text{Group II}\\ \text{P}& \text{Hydrologic flood routing}& \text{1.}& \text{Continuity equation}\\ \text{Q}& \text{Hydraulic flood routing}& \text{2.}& \text{Momentum equation}\\ & & \text{3.}& \text{Energy equation}\end{array}$
The correct match is

• A. P - 1; Q - 1, 2 & 3
• B. P - 1; Q - 1 & 2
• C. P - 1 & 2; Q - 1
• D. P - 1 & 2; Q - 1 & 2

Answer 1

The correct option is B P - 1; Q - 1 & 2
