Description

The Streamflow prediction application is the collection of river network created within specific countries which has the unique ID which then is connected to the database to have the 48-hours forecast. The user can interact by clicking this river network. This application can be a part of a DSS tool for flood forecasting and give an early warning system to the user.

Data /methodology/platform

The Streamflow Prediction Tool provides 48-hours streamflow predicted estimates by using the High-Impact Weather Assesment Toolkit (HIWAT) runoff predictions routed with the RAPID program. The application displays only results from rivers that are not transboundary. The app also provides historical data, and the ability to download the forecast and historical data.

On the other hand Tethys platform is the open-source web-GIS suit developed by Brigham Young University (BYU). Tethys comes with few widely used GIS technologies like GeoServer and PostGIS and is developed in the python Django environment.
