Hydrological analysis is a common task in environmental and geospatial applications. However, many
users of QGIS encounter challenges when they want to perform stream and catchment delineation or
morphometric analysis of streams and catchments using various processing provider plugins. These
plugins, such as PCRaster, SAGA, GRASS and WhiteboxTools, offer different algorithms and methods for
hydrological analysis, but they also require different installation procedures and have different
limitations and assumptions. In this presentation, we will review the main features and drawbacks of
these plugins, and provide practical tips and examples on how to use them effectively in QGIS. We
will also compare the results of different algorithms and discuss the implications for hydrological
analysis workflows. By the end of this presentation, you will have a better understanding of the
available tools and techniques for stream and catchment delineation in QGIS, and how to choose the
most suitable ones for your projects.
