Show answer and explanation

Correct answer: (B) I true, II false

Explanation

Goodrich reservoir routing uses storage and continuity, a hydrologic approach. Muskingum also uses a storage–inflow–outflow relation and continuity; it does not solve the full hydraulic momentum equations. Therefore I is true and II false: **B**.
