Description

From the listing uploaded by “appupdater”.

The BachApp is a practical and informative app for anyone who enjoys spending time around the Rhine, Wiese and Birs. It contains: - River information: Current measurement data (water temperature, water level and discharge (incl. forecasts) for the Rhine, Wiese and Birs - Map: The map can be filtered and contains practical information on places around the rivers, e.g. recommended swimming areas, toilets, food and drink, barbecue sites and more. - Info: In addition to interesting facts about the Rhine, you can find out about upcoming events on the Rhine and where there are construction sites. - On the river: This section answers frequently asked questions, introduces various water sports and provides information on respectful coexistence (#RHYLAX) and nature conservation. The majority of the measured values and information available in the app flow into the BachApp via the cantonal data portal (https://data.bs.ch). This ensures that the information corresponds to the latest available status at all times. In addition, the data is also available to the public online as open government data (OGD) at https://data.bs.ch/explore/?q=tags=BachApp. Translated with DeepL.com (free version)
