This zip contains three model runs of the nwm 1.2 in analysis assimilated configuration. The model underwent a spin-up period of 1 year (2010) using default setting prior to these three runs. NLDAS2 data was used for forcing and was unadjusted for these three model runs. Inside the zipped directory you will find three directories that pertain to the three model runs. There is a control model run where no channel parameters were adjusted and two other model runs where a constant scalar was multiplied against the channel parameter 'BtmWdth' in the Route_link.nc file. The two scalars are 0.5 and 0.7. These were chosen with the knowledge that in version 2.0,of the nwm, bottom width is equal to 0.6 * top width that is calculated using a power equation found in Blackburn-Lynch 2011.
