Monthly Runoff Estimates by Hydrographic Subzone in Colombia, 1982–2023

IDEAM's dataset provides monthly estimates of total surface water supply (runoff) for Colombia from 1982 to 2023, modeled at the hydrographic subzone level. The data allows for the identification of spatial and temporal variability in the country's runoff. It is published as open data in compliance with Law 1712 of 2014.

Use Cases

• Analyzing temporal runoff trends for specific subzones like '2802/Medio Cesar' or '3101/Río Inírida alto' over the 41-year period.
• Modeling spatial variability of water supply by comparing monthly runoff values across different subzones such as '4505/Río Luisa' and '3204/Río Guayabero bajo'.
• Correlating runoff data from columns like '2909/Ciénaga Mallorquín' with other climatic or land-use datasets for integrated watershed management.

Strengths

• Covers a long temporal range from 1982 to 2023.
• Provides data at a detailed spatial scale (hydrographic subzone) for over 29 listed subzones.
• Available in multiple machine-readable formats including CSV, JSON, XML, and RDF.

Limitations

• The data provider states the data is raw, unvalidated, and may contain errors or inconsistencies from sensor failures.
• Row count and total dataset size are unknown, limiting suitability assessment for large-scale ML.
• The description notes data may have time lags due to sensor transmission frequencies.
