Google's Ngram viewer isn't working for the term "Ben Gurion Canal" for some reason, but it would show approximately when renewed interest started getting traction since the proposal was declassified in 1996.
I wouldn't be surprised if the 2021 Evergreen fiasco was contributory to this renewed interest but this is pure speculation on my part.
