I work at the Arava Drainage Authority and Regional Council in southern Israel, doing hydrological analysis and general mapping. Involved with open source software since 1996, and FOSS GIS since 2006. I've also organized a few short GIS training seminars based on open source software.

Two more ideas: I think that v.out.ascii adds a third column with the cat value. So you'll have to add to your "while read" like so: while read X Y cat; do.... Also you might need to quote the variable $i as ${i}.

What does your cross_points.txt look like? Also, in case you are not already aware: each X,Y must fall exactly on a drainage line.

comment Calculating area of an EPSG:4326 Polygon
The calculations of ST_Area (and other functions) will always be in the same units as the Coordinate System. The above refers to UTM, with units in meters, so the area will be sq meters.

comment QGIS vector edition corrupts SpatiaLite attribute table
I can verify the problem on 2.6 Win64. You must save right after splitting a feature. Only then can you continue editing.
