• Concept of Linear Reservoir in Hydrology:
• In catchment hydrology and linear flood routing (Nash and Clark models), a linear reservoir is a conceptual reservoir in which the storage ($S$) is directly proportional to the outflow rate ($Q$):

where $K$ is the storage constant (lag time).

• Conclusion: Storage is directly proportional to Outflow (Option 2).

Correct option: (2) Outflow
