Water class hard coded in NWM IO.

[kafitzgerald]

Thanks to a WRF-Hydro user for pointing out the following issue.

I'll put in a PR shortly that should be applied to v5.0.x (if we're still maintaining this version), v5.1.x, and master.

##Expected Behavior
Only water classes should be filled with NaNs in NoahMP outputs.

Current Behavior

Land use category 16 is getting filled with NaNs for a valid land class in the MODIS categories. Effectively, the water category for the USGS classes was hard coded in the output routines.

Possible Solution

Change the following hard coded waterVal = 16 to waterVal = rt_domain(domainId)%iswater

wrf_hydro_nwm_public/trunk/NDHMS/Routing/module_NWM_io.F

Line 1124 in 80395eb

waterVal = 16

Steps to Reproduce (for bugs)

Run the model with MODIS land use categories and output LDASOUT files with NWM output routines.
