- DA-1, B-3, C-4, D-2
Solution
Concept
Matching standard hydrological methods and equations to their respective applications in water resources engineering.
Step-by-step solution
1. Match Infiltration with Horton's equation -> A-1 2. Match Peak discharge with Rational method -> B-2 3. Match Reservoir routing with Storage-indication method -> C-3 4. Match Flood frequency with Gumbel method -> D-4 5. Combine the pairs to get A-1, B-2, C-3, D-4.
Explanation
Infiltration capacity is commonly modeled using Horton's equation. Peak discharge for small catchments can be estimated using the Rational method. Reservoir routing frequently utilizes the Storage-indication method (Modified Puls method). Flood frequency analysis is standardly performed using the Gumbel method for extreme value distributions.
Shortcut
Look for direct definitions like Rational method for peak discharge or Gumbel for flood frequency to quickly eliminate wrong options.
Common mistake
Confusing reservoir routing methods (like storage-indication) with channel routing methods (like Muskingum).
Correct answer: A) A-1, B-2, C-3, D-4
