Nowadays, the design criteria of Dutch Delta works are based on:
• historical observations(return periods of extremes and trends)
• projections of future climate

Historical observations
• Regional information is more scattered; many different sources:
1) in-situ observationslong-term records (50-100yr) but sparse
2) t llit li t d t d2) satellite climate data recordsspatially extensive but short (<30yr)
3) (regional) reanalyses of past weathercomplete but expensive and some bias

Final remarks: user interaction
• Interaction between providers and stakeholders helpsspecify the needs in more detail
• I t t t di d i t th t i ti• Important to discuss and communicate the uncertainties(due to emissions, model limitations, internal variability, observational gaps/changes and errors)
• Lesson learned: guidanceinformation is crucial
