Parameter Description Document for 1) NWM Model and 2) NWM Coastal Module Parameters


1) Current NWM v3.0 parameter files
---------------------------
 * "DOMAIN" below can be:  
 *   CONUS, AK, PRVI or HI for Continental United States, 
 *   Alaska, Puerto Rico / US Virgin ISlands, and Hawaii domains


* Fulldom_CONUS_LongRange.nc
File description:  This file contains gridded physiographic and model parameter
data for the 'Long-range' and 'Long-Range Analysis', configurations of the National Water Model (only for CONUS).


* Fulldom_DOMAIN_FullRouting.nc
File description:  This file contains gridded physiographic and model parameter
data for the 'Analysis and Assimilation', 'Short Range' and 'Medium Range'
configurations of the National Water Model.


* LAKEPARM_DOMAIN.nc
File description: Provides the static parameters that describe the initial
fullness, size (in terms of surface area and maximum elevation), and discharge
mechanisms (orifice and weir) for each NWM waterbody. The lake_id corresponds
with the NHD+WaterbodyComID


* nudgingParams_DOMAIN.nc 
File description: Channel_rt nudge parameters. Supplies the parameters for the
application of streamflow nudging data assimilation within the model


* RouteLink_DOMAIN.nc
File description:  This file contains river channel definition and parameter
data, and USGS stream gauge river reach definitions used in all configurations
of the National Water Model.


* spatialweights_CONUS_LongRange.nc
File description:  This file contains the spatial regridding weights, used to
map variables from the 1km WRF-Hydro model grid to the NHDPlusv2 catchment
objects used in the 'Long Range' and 'Long Range Analysis' configurations of the National Water Model.


* spatialweights_DOMAIN_FullRouting.nc
File description:  This file contains the spatial regridding weights, used to
map variables from the 100m/250m WRF-Hydro model grids to the NHDPlusv2 catchment
objects used in the 'Analysis and Assimilation', 'Short Range' and 'Medium
Range' configurations of the National Water Model.


 


2) Current NWM v3.0 Coastal Module (SCHISM) parameter files
