lining concrete side ditch?
i would like to protected slope by concrete lining on side ditch.
it necessary to have reinforce steel?
thank you

it depends of what work you are referring to. if subject to some mandatory code, there will be the answer. if not, and only as something of your intent, you may decide if make of the stream a channel, or proceed along the ways you indicate.
whenever some concreting is done on slopes, it is usual to include some steel mesh, what in itself is a measure of the general misconficdence in that the thing is going to stay uncracked, for it is typical of slopes to have loose debris and be subject to washing actions by rains.
at the always wet side of a ditch, the same circumnstances happen, and just shrinkage of concrete on such loose base might break the lining from the start. anyway don't put either too much steel for too little concrete, since then the steel itself may contribute to shrinkage cracks.
