TYPE: ENHANCEMENT
KEYWORDS: diversions,DA,channel routing
SOURCE: NCAR
DESCRIPTION OF CHANGES:
Add initial support for channel diversions. This PR only covers the 'gage-assisted diversion' as used on the Mississippi at the Old River Control Structure.
TESTS CONDUCTED:
NOTES:
Diversions must be specified in a
diversions_file
added to thehydro.namelist
. The format of this file will be documented later as part of the NWM v3.1 release.This PR introduces a small amount of C code to find USGS Timeslice files, and as such, introduces a new model dependency on a C compiler and a POSIX-compliant operating system. This should not pose an undue burden on the vast majority of users.
