Consider the following statements:
Statement 1: Goodrich method for reservoir routing is based on hydrologic flood routing method.
Statement 2: Muskingum method for channel routing is based on hydraulic flood routing method.
Which one of the following is correct?
Statement 1: Goodrich method for reservoir routing is based on hydrologic flood routing method.
Statement 2: Muskingum method for channel routing is based on hydraulic flood routing method.
Which one of the following is correct?
Show Hint
Hydrologic routing uses only continuity equations; hydraulic routing uses full dynamic equations. Muskingum is always hydrologic.

- Statement 1 is false; Statement 2 is false
- Statement 1 is true; Statement 2 is false
- Statement 1 is true; Statement 2 is true
- Statement 1 is false; Statement 2 is true

Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Flood routing methods are used to estimate how a flood wave propagates through reservoirs or channels.
Step 1: Goodrich method.
Goodrich method is a \textit{hydrologic} flood routing technique, meaning it uses continuity equations without considering momentum terms. Hence, Statement 1 is true.
Step 2: Muskingum method.
The Muskingum method is also a \textit{hydrologic} flood routing technique — not a hydraulic one. Hydraulic routing uses Saint-Venant (momentum + continuity) equations, whereas Muskingum uses storage-discharge relationships. Hence, Statement 2 is false.
Thus, the correct option is (B).
Final Answer: (B)

- In a 30 m$^3$ room, a stove in operation consumes wood at the rate of 0.25 kg/h. The inflow and outflow rate of air in the room is the same, i.e., 500 m$^3$/h. This stove emits a VOC species at a rate of 0.2 g/kg-wood. The VOC species gets converted to CO$_2$ at a rate of 0.4 per hour. Given: (i) the air in the room is completely mixed, (ii) initial concentration of the VOC species in the room is negligible, and (iii) concentration of the VOC species in the air entering the room is negligible. The concentration of the VOC species due to two hours of stove operation in the room is __________________________________ (in $\mu$g/m$^3$, rounded off to one decimal place).
