EXPLANATION
Stream Gauging & Hydrograph Analysis
- Factors Governing Streamflow Hydrograph Characteristics:
- streamflow hydrograph is determined by the complex interplay of three primary physiographic and hydrometeorologic drivers:
- Rainfall characteristics: Rainfall intensity, duration, spatial distribution, storm direction, and storm recurrence interval.
- Catchment characteristics: Watershed area, shape (compact vs elongated), average land slope, drainage density, channel roughness, and soil hydraulic conductivity.
- Climate factors: Ambient temperature, solar radiation, relative humidity, and wind speed governing antecedent soil moisture depletion through evapotranspiration.
- Conclusion: (A), (B) and (C) (Option 3).
Correct option: (3) (A), (B) and (C).
