Hi Jordan. You can use ArcHydro tools under ArcGIS 10.1 or later to process DEM and to further analyse terrain, flow direction and many more analysis. In QGIS you can use TauDEM (Hydrology Analysis). If not clear how to work with TauDEM you can find on google many tutorials (https://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=24&cad=rja&uact=8&ved=2ahUKEwi7yMmphfXfAhUj_CoKHRPrDKwQFjAXegQIChAC&url=https%3A%2F%2Fwww.engenious.com%2FContent%2FTutorial.pdf&usg=AOvVaw0M8E5dZvOuBnI1Gm6wgsM8)
Hope this is useful.
