Q2. After several years of summer fun, and with the corresponding government licenses, the association filled the pond with a horizontal compacted cohesionless backfill so that new houses could be built on the newly developed area (see Fig. 2). Assume that the original smooth vertical surface of the retaining wall and the drainage system were kept the same so that no friction occurs between the wall and the backfill. The water table can only rise to the original water level of the pond. Find the stress distribution diagram beneath the retaining wall during both (i) dry and (ii) rainy seasons. For the dry season, assume that the water table drops far below the base of the wall. Compare and discuss the results obtained from (1).

Question

I need detailed help solving this exercise from homework of Foundation Engineering.
I do not really understand how to do, please do it step by step, not that long but clear. Thank you!

Q2. After several years of summer fun, and with the corresponding government licenses, the association filled the pond with
a horizontal compacted cohesionless backfill so that new houses could be built on the newly developed area (see Fig. 2).
Assume that the original smooth vertical surface of the retaining wall and the drainage system were kept the same so that no
friction occurs between the wall and the backfill. The water table can only rise to the original water level of the pond. Find
the stress distribution diagram beneath the retaining wall during both (i) dry and (ii) rainy seasons. For the dry season, assume
that the water table drops far below the base of the wall. Compare and discuss the results obtained from (1).
