Hourly Minimum River Level Measurements from Colombia

Hourly minimum river surface levels are recorded across Colombia's hydrological stations. The data is provided as raw, unvalidated sensor readings by Colombia's Institute of Hydrology, Meteorology and Environmental Studies (IDEAM). Records include measurements such as 'ValorObservado' and 'FechaObservacion'.

Use Cases

• Model flood risk by analyzing 'ValorObservado' (observed value) trends against historical thresholds for specific 'NombreEstacion' (station name).
• Correlate water levels with geographic features by joining data on 'Latitud' and 'Longitud' coordinates with regional precipitation datasets.
• Forecast minimum river levels using 'FechaObservacion' (observation date) and 'ValorObservado' as a univariate time series.
• Assess sensor network coverage by mapping station locations ('NombreEstacion', 'Municipio', 'Departamento') against 'ZonaHidrografica' (hydrographic zone).

Strengths

• Data includes geographic context via 'Latitud', 'Longitud', 'Municipio', and 'Departamento' columns.
• Provides sensor metadata via 'CodigoSensor' and 'DescripcionSensor' for traceability.

Limitations

• Data is explicitly unvalidated and may contain errors or values outside normal limits.
• Records may have transmission delays, introducing potential temporal gaps or lateness.
