I need a tool in QGIS that has the same functionality as the ArcHydro Tools from ArcGIS.

QGIS incorporates the functionality of the major open source GISes (GRASS, SAGA, ...) and thus you might hava a look at GRASS GIS r.watershed module, as far as I see its functionality is compareable to those of ArcHydro Tools. In this context consider also r.water.outlet and r.gwflow. Just type the name of the module in the search of the processing toolbox (Processing > Toolbox...):

TauDEM might be the toolset you are looking for. TauDEM includes an ArcGIS toolbox if and only if you have ArcGIS installed on your Windows computer.
