Streamflow

• Streamflow refers to the movement of water in natural streams, rivers, and creeks.
• Streamflow - it is a fundamental component of the hydrological cycle, crucial for various ecological, economic, and societal functions.
• Streamflow provides freshwater for drinking, irrigation, and industrial use. It sustains aquatic ecosystems, supporting biodiversity. It plays a role in flood control, hydropower generation, and navigation.
• Key Factors Influencing Streamflow

  • Precipitation Patterns
  • Precipitation Patterns
  • Geology and Topography
  • Land Use and Land Cover
  • Urbanization
  • Agriculture
• Measurement and Monitoring of Streamflow

  • Direct Methods - Includes stream gauging stations and flow velocity measurements.(Flow meters, stage-discharge relationships, and water level sensors, weirs, pitot tube)
  • Indirect Methods - hydrological models and remote sensing techniques.
