On a marine seawall project, the groundwater table is located 2 feet above the mudline and tidal fluctuation is about 3 feet. Why must the design account for rapid drawdown conditions behind the wall?

Rapid drawdown reduces the buoyant unit weight of the soil, increasing effective stress Rapid drawdown leaves saturated backfill behind the wall while the water in front drops, creating a large unbalanced hydrostatic load Rapid drawdown increases the passive resistance in front of the wall, overstabilizing the toe Rapid drawdown has no effect because the water levels equalize instantly through the soil

Correct Answer:

Rapid drawdown leaves saturated backfill behind the wall while the water in front drops, creating a large unbalanced hydrostatic load
