<p>It should be noted that we do not fully outline how to set up a WRF-Hydro model here and this page intended to give only general advice on the build process in reference to using WRF-Hydro with the CUAHSI NWM subsetting tool. WRF-Hydro is extensively documented by the development team at NCAR and you should refer to the [WRF-Hydro Modeling System website] (https://ral.ucar.edu/projects/wrf_hydro/overview) and the links below for general WRF-Hydro information.<br />For additional [user support] (https://ral.ucar.edu/projects/wrf_hydro/contact), please contact <script type="text/javascript">

<li><p>#####Compile with nudging turned off<br />The CUAHSI Domain Subsetting Tool: NWM v1.2 does not currently support subsetting Nudging files. As such, the model must be compiled using the NoahMP land surface model (LSM) with NUDGING TURNED OFF in the <code>setEnvar.sh</code> script (<code>export WRF_HYDRO_NUDGING=0</code>).</p></li>
