AquaFetch: A Unified Python Interface for Water Resource Dataset Acquisition and Harmonization

AquaFetch is a Python package designed for the automated downloading, parsing, cleaning, and harmonization of freely available water resource datasets related to rainfall-runoff processes, surface water quality, and wastewater treatment. The package currently supports 70 datasets, downloading and transforming raw data into consistent, easy-to-use analysis-ready data. This allows users to directly access and utilize the data without labor-intensive and time-consuming preprocessing.
