Interestingly the biggest canal built before Panama and Suez was the Manchester Ship Canal and there was some interesting insights into its building. For example the engineer in charge basically invented the bucket dredger to get the job done in time and when the canal flooded half way through its building he invented the floating bucket dredger.
Prog. is well worth looking at though do not know when it will be repeated.
