Matching Flow Conditions with Scenarios

This question requires matching different types of flow conditions (LIST-I) with specific hydraulic scenarios (LIST-II). We will analyze each item in LIST-I and find the most appropriate match from LIST-II based on the provided correct answer.

Analysis of Matches:

• A. Gradually varied flow with increasing discharge is matched with IV. Drainage ditch. This scenario often occurs in drainage systems during rainfall events when discharge increases over time and space.
• B. Turbulent flow is matched with I. Hilly river on steep slope. High velocities and depths in such environments typically result in turbulent flow conditions.
• C. Drop structures are matched with III. Pipe inlet. Drop structures are used to manage flow and dissipate energy, often implemented at locations like pipe inlets where there is a significant change in elevation or flow control is needed.
• D. Gradually varied flow with decreasing discharge is matched with II. Irrigation canal. Water is frequently drawn off along the length of an irrigation canal for distribution, leading to a gradual decrease in discharge downstream.

Conclusion:

Based on the analysis, the correct matching is A-IV, B-I, C-III, and D-II.
