Apr 22, 2015 at 5:57 comment added Chris W @MichaelMiles-Stimson Nothing particularly complicated. Assuming river lines are topologically correct and ready for quick import as a network, the Service Area solver is basically a 'along the line buffer' tool and it can automatically snap input points to the nearest point on the network, eliminating that step/tool. Output can be lines or polygons. Lines would let you skip to the 20m buffer step of your comment, polygons might take some tweaking (gis.stackexchange.com/questions/93603).
Apr 21, 2015 at 23:55 comment added Michael Stimson Absolutely @ChrisW, is that 100m 'as the crow flies' or 100m of bank, measured along the polyline from the point... then again, are we over thinking the problem? More info is needed on what exactly is 100m of bank before composing an answer. I would like to see the Network Analyst solution, I haven't had much to do with that extension and wouldn't mind seeing how this would solve it - could come in handy later.

Apr 21, 2015 at 23:01 comment added Chris W Any chance you have network analyst? I just thought of a 'cheat' using the Service Area solver that would make short work of this.

Apr 21, 2015 at 22:40 comment added Chris W @MichaelMiles-Stimson that wouldn't be a true 100m buffer given the curve. It might be 'close enough' but in theory an accurate solution is going to have to use linear referencing.
Apr 21, 2015 at 22:15 comment added Michael Stimson Buffer the point on the river bank by 100m, clip the river boundary (do you have just the boundary?) and buffer by 20m (end type flat) then erase by the river to remove the section inside the river. If you're wanting a batch solution does that include arcpy? model builder? ArcObjects?
