To help facilitate you, our partners, and other interested parties in applying one of the world’s most comprehensive hydrological models, namely SWAT+, we have prepared a guide for how to access key global data sources, which enable model applications for any location in the world.
We offer this guide and datasets with the hope that more people, including students and professionals, will be able to apply complex models such as SWAT+, which could ultimately support a more widespread use of state-of-the-art science in decision-making processes.
SWAT+ requires four key data sources for its applications (see below).
In this page, you can learn how to acquire all these data from free globally available sources, which will allow you to set up a model from scratch, for any location in the world.
We have also produced a series of video tutorials, which demonstrate how you may process these global datasets by a series of GIS operations (e.g. clipping data for your area of interest), so that they can be applied in the SWAT+ model.
Please visit our Training page to find these videos.
When setting up a SWAT+ model, the model user will make a range of choices. To be able to reproduce a model set up, it is very useful have at least a minimum of documentation of the choices made. This includes information on the model code versions, input data sources, and model configuration choices.
WaterITech have prepared a model protocol template, which seeks to document key aspects of a model application. This will enable an experienced SWAT+ user to reproduce the SWAT+ set up from scratch.
