Review and provenance

Specialist reviewer: not recorded. Review date: not recorded.

Dataset workflow: proposed. This is separate from specialist review.

Confidence describes the stated assessment; it does not certify expert approval. How review works.

Chronology

Dating intervals may describe uncertainty or phases; their width alone does not establish event duration.

Preferred assertion

1600 BCE–1000 BCE

Precision: broad calibrated range subset

Chronology model: Ma'rib early irrigation onset model

moderate

Geoarchaeological evidence places irrigation onset somewhere within a much broader 2500–1000 cal BCE range; this event displays only the primary-interval overlap.

Interpretation and caveats

The evidence supports local irrigation development but cannot assign a start century, king, polity or the later Great Dam’s final form.

Event context

Classification

Event type: irrigation landscape development

Evidence layer: archaeological

Timeline role: regional core

Why it matters to the timeline

The event directly addresses requested irrigation antecedents while preserving the source’s broad dating.

Research notes

  • Provides the geoarchaeological date and its low resolution. Role: dates. Locator: pp. 1305–1310; broad 2500–1000 cal BCE onset range.
  • Provides the direct evidence. Role: provides archaeological observation. Locator: Palaeosol and irrigation-sediment results.
