watershed elevation accuracy in tables and text
Opened this issue · 2 comments
should link to similiar issue in bulkley 2022 if it exists
because of the way watershed areas are generated upstream of a point by fwapg
using the elev_min
is not a good representation of the elevation of the crossing and although the overall polygon created represents drainage area well - elev_min
is not often accurate at all. for that reason it woiuld be best to remove elev_min
from the object at the start (perhaps right after the pull from the sqlit in the tables script) and use the elev_site
numbers to communicate
ex. Pinenut
"The elevation of the watershed ranges from a maximum of 1964m to 420m near the crossing"
however its actually about 150m lower....

there was discussion regarding removing elev_min
column in a PR
Hm. Useful info though. Probably best to just filter out the Wako elevations and leave the rest in the table, but perhaps just reference site elev in text.
