= Q1. After applying for all corresponding permits with the local government, a neighborhood association built an artificial pond so the neighbors could enjoy swimming and sailing during the scorching summer months (see Fig. 1). If the unit weight of the reinforced concrete used to build the vertical retaining wall is Yc 24 kN/m³, find the stress distribution diagram beneath the retaining wall. Assume that the friction on the bottom surface of the retaining wall prevents sliding. A smooth plastering was applied on the vertical wall to create an impermeable barrier against water filtration. Note that the pond's water level does not reach the top of the retaining wall due to the installation of an overflow drainage system.

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.
