2018 Ssc avg width of 0 #5

Closed KevinSee closed 2 years ago

KevinSee commented 4 years ago

In the 2018 data, there are 2 small side channels with an average width of 0. They are: UpperLemhi_2018, hab_rch 3, cu_id 012 UpperSalmon_2018, hab_rch 10, cu_id 062

This seems incorrect.

Upper Salmon CU #62 has 4 legit widths in the CU_1.csv Survey123 table, but one with a 0. That table says Avg_width is 1.56, but somehow it got turned into a 0 along the way. There is a note that says "disconnected at the bottom". Should this be an off-channel area then, and not a small side channel? Or should we just replace the avg width in the shapefile "US_Line_Fish.shp" with 1.56 (since it's now 0 for some reason)?

The Upper Lemhi CU #12 was deemed a dry small side channel, and has 5 recorded widths of 0.

Maybe we need an indicator of whether a channel unit is dry at the time of the survey? Or maybe we should drop those channel units as part of the roll-up? There may be other dry channel units that weren't included in the channel unit demarkation. The fact that this one was: does that imply it was wet when someone marked channel units, but was dry when they went back to survey it? @rcarmichael3 do you have any thoughts about this?

Resolved just now. I obtained widths for Upper Lemhi MRA 2019, cu 012 from drone orthomosaic. Upper Salmon (Decker Flat MRA), cu 062 was since removed because it was disconnected from the river channel.
