January 23, 2017 Seventh Symposium on Advances in Modeling and Analysis using Python 97th AMS Annual Meeting, Seattle, Wash. WRF-Hydro System • WRF-Hydro (Gochis et al. 2013) is WRF hydrological extension package • Run in uncoupled or coupled mode • Contains column land surface, terrain routing, and channel routing modules • Supports multi-scale domains, so each module may require input grids at different spatial resolutions (NCAR 2017) (NCAR 2017) WRF-Hydro GIS Preprocessing Tool • Derives WRF-Hydro terrain routing and channel routing grids using ArcGIS hydrology tools • Channel routing grids include channel grid and lake grid. • Inputs: • WRF Preprocessing System (WPS) GEOGRID file • High-resolution Digital Elevation Model (DEM) • NCAR working to make tool 100% open- source Python • Preprocessing Tool Documentation: Sampson and Gochis 2015 Screen capture of WRF-Hydro GIS Preprocessing Tool within ArcGIS WRF-Hydro GIS Preprocessing Tool • Channel grid derived from high- resolution DEM (Sampson and Gochis 2015) WRF-Hydro GIS Preprocessing Tool • Channel grid derived from high- resolution DEM • Insert reservoirs/lakes using lake shapefile (Sampson and Gochis 2015) WRF-Hydro GIS Preprocessing Tool • Channel grid derived from high- resolution DEM • Insert reservoirs/lakes using lake Stream shapefile artifact • Lake polygon rasterized to mask channel grid • Lakes numbered 1 to n • Stream artifacts may result (Sampson and Gochis 2015) WRF-Hydro GIS Preprocessing Tool • Preprocessing Tool does not remove stream artifacts • Stream artifacts must be removed prior to running WRF-Hydro • Straightforward, programmatic method not available • Can be done interactively in Python using TkInter module Stream artifact Channel grid Lake grid TkInter – A Python Graphical User Interface • Provides basic Graphical User Interface (GUI) TkInter Widgets within Python Button • Contains classes which allow display, Canvas Checkbutton positioning, and control of widgets Entry • Wrapper functions for Tcl/Tk Frame Label • Importing TkInter LabelFrame Listbox OptionMenu PanedWindow Radiobutton Scale • Online documentation and resources: Scrollbar Spinbox • https://wiki.python.org/moin/TkInter Text • http://tkinter.unpythonic.net/wiki/ Tk • http://infohost.nmt.edu/tcc/help/pubs/tkinter/tkinter.pdf Toplevel *Spyder 2.3.8, Python 2.7, TkInter 8.5 Applying TkInter – Interactive Python Widget *Spyder 2.3.8, Python 2.7, TkInter 8.5 Interactive Python Widget Merged grid Lakegrid showing both number Full domain channels and lakes Lake Channel Node / outlet Land Lake location Lake inset
