Flow simulation is an important task for engineering and disaster management. From the free softwares available for flow simulation, HECRAS is a strong alternative for its continuous development, the capability to simulate many flow types, and the interaction with other softwares like QGIS or MODFLOW.

QGIS is a free and open source software Geographical Information System (GIS) application. There is a environment of available plugins in QGIS that perform specific tasks of analysis, representation and preprocessing. There are QGIS plugins related to HECRAS, in this tutorial we will use the QRAS plugin to develop a basic example of flow model geometry construction in QGIS and steady flow simulation in HECRAS.
