A 1.2 m tall, 203mm wide concrete retaining wall is built as shown. You have been told that the density of concrete can range anywhere from 2350kg/m³ to 2450kg/m³. The wall simply rests on the ground without being anchored to it. During a heavy rain, water fills the space between the concrete wall and the earth behind it to a depth h. a) As a group - discuss and decide on an appropriate value for the density of concrete b) Assuming the water pressure under the concrete wall is zero, what is the maximum water depth h possible without the concrete wall tipping over? c) Assuming the water pressure under the concrete wall is uniform and equal to the maximum water pressure behind the wall, what is the maximum water depth h possible without the concrete wall tipping over? 1.2 m 203 mm cohesive sediment
