A mobile app called SWOC-FFC was created to warn people about floods in the Chao Phraya River Basin. The app uses a flood forecasting model to predict flood levels up to 7 days in advance. The data is stored on a web server and then sent to the app for users to see. The app shows flood information in different ways, like a picture of the river and warning levels. During the October 2021 flood, the app was tested and found to be reliable.
