Hello Sir(s) & Madam(s),

I am a very beginner in Structural Designing.
I got an assignment to design a retaining wall near a bank of a channel.

Previously there was a retaining wall but failed due to scouring and collapsed.

Details:
Total length of the wall would be around 50m
Natural Channel: 5m width and 3m depth from NGL to bed level.
Backfill is clayey soil and 5m away from the wall there is a  RCC building.

So Sir could you all please say me
1.Whether a RCC retaining wall would be better or a RRM wall.
2. And how to assume a Scouring depth for this case (as fund is a constraint here so piling is not prefered).

I have attached a picture of the collapsed wall below.

Thanks

Sincerely
Samim Ahmed
