SWOT and Water Management
What can we do with SWOT data? What are
the policy implications that these data would
have for water management? Daniel P.

SWOT and Water Management

• Water Management
• Keeping everyone happy
• With better data (forecasts) we can manage water
  better.
• Will we? Mainly a social science issue.

• Possible Management Applications?
• DEM-based automated extraction of river basin
  and network geographical / topographical data
• Improved input and parameter data for
  distributed rainfall-runoff modeling
• Source of hydrologic data for missing or gaps
  in records. for planning and management
• Predictions of future flows, elevations,
  volumes
• Improved real-time management (more effective
  joint reservoir operation, transboundary ops.)
• Flood wave prediction in large basins, coastal
  areas
• Other?

Depends on time and space scales

Watershed / River Basin Delineation
Hydrogeomorphic properties (e.g. flow direction,
upslope area, stream network, wetness index,
hypsographic curves, width-function) for better
rainfall-runoff modeling.

• Issues
• Temporal and spatial resolution
• Ground truth calibration, precision,
• quality assurance and control?
• Data management, processing and
• timely communication
• Institutions. Regulations. Laws.
• Policy implications increased liability?

Need for a data integration framework to meet
standards and requirements
