Navigation guide

Map views support the usual zoom functions and selection tools. Hoover boxes, filters and search fields will help you find suitable stations. Table views with configurable columns allow a more detailed selection. Selection of several items is summarized into one download. Disable your previous selection before starting a new one.

To start a data download, select your subregion or stations of interest, click on the download button, complete the form, choose your preferred export format and agree to the terms of use and data sharing conditions. You will receive a confirmation and a request ID. A download link will be sent within 24 hours to the email address you entered. Due to technical reasons, it may take a few minutes after receiving the download link before data is available on the server. Please mention the request ID when making any inquiries about your download.

To download the associated "Watershed boundaries of GRDC Stations" (basin polygons in GeoJSON format) activate the tick-box in the data request form.
