hydrology 4.0.2

Load data from the UK Hydology API

Hydrology API

This package was build for my own use, please feel free to use it but it may have bugs

This package loads data from the UK Hydrology API. The API provides:

• River Level, Flow and Water Quality Data
• Rainfall Data
• Groundwater Level Data

This package currently only provides access to the River Level, Flow, and Rainfall. Data is returned as a polars DataFrame. After the first request of a given dataset, the data is cached for up to a week.

Example

>>> from hydrology import HydrologyApi, Measure
>>> from datetime import datetime
>>> api = HydrologyApi()
>>> 
>>> # Get all stations that record the water level along the River Wear in Durham
>>> stations = api.get_stations(Measure.MeasureType.LEVEL, river="River Wear")
>>> 
>>> df = api.get_measures(
>>>     [
>>>       Measure(station_id, Measure.MeasureType.LEVEL) for station_id in stations["station_id"]
>>>     ],
>>>     stations,
>>>     start_date=datetime(2020, 1, 1),
>>> )
>>> 
>>> df.head()
shape: (5, 6)
