Flood Flow Velocities for 36 Populated Centers in Colombia at 1:2000 Scale

A geospatial map of flood flow velocities indicating speed ranges for a 50-year return period across 36 populated centers in Colombia, created at a 1:2000 scale. The data is provided by www.datos.gov.co and was last updated on 2026-05-22. The raw data is made available for transparency and risk management support under the terms of Colombia's Law 1712 of 2014.

Use Cases

• Modeling flood hazard exposure by correlating flow VELOCIDAD with populated center CENPOB and municipality MUNICIPIO.
• Calculating potential flood impact areas by analyzing the SHAPE_Area and AREA_TOT of velocity zones.
• Regional risk analysis by aggregating velocity data by DEPARTAMEN (department) and MUNICIPIO.

Strengths

• Contains specific flood velocity data for a 50-year return period, a key metric for infrastructure design.
• Covers 36 distinct populated centers (CENPOB) across multiple municipalities and departments.
• Provides detailed geospatial geometry (the_geom) at a 1:2000 scale for precise mapping.

Limitations

• The data provider (IDEAM) states the data is raw, unvalidated, and may contain errors or inconsistencies from sensor failures.
• Row count is unknown, which may limit suitability assessment for large-scale modeling.
• Update frequency is described as 'eventual', and the stated last update date is in the future (2026-05-22), indicating potential metadata issues.

Provenance

Source

www.datos.gov.co, likely sourced from IDEAM (Instituto de Hidrología, Meteorología y Estudios Ambientales) sensor networks or inter-administrative agreements.

Collection Method

Likely generated from hydraulic models or sensor data from automatic stations, though the specific methodology is not detailed.

Time Range

The data represents modeled conditions for a 50-year flood return period; the specific year of model creation (ANO) is a column but its value is unknown.

Freshness

Last updated 2026-05-22 06:10:01; however, the description states updates are 'eventual' and the future date suggests metadata may be inaccurate.

Geography

Covers 36 populated centers (CENPOB) within municipalities (MUNICIPIO) and departments (DEPARTAMEN) in Colombia.
