The results from the new pressure test design were consistent with degradation of soil, as the slope angle decreased by 3.83%. The measurements from the height, slope, and bottom did not change as expected. The slope actually decreased instead of increasing, the bottom increased very slightly, and the height remained almost exactly the same. We think the change in angle came from a compression of the soil rather than the soil sliding but both are issues within soil erosion. The measurements were taken from immediately after bricks were placed and after 30 minutes of them being on top of the soil.
This new style of testing can have improvements in the future, such as where to place the bricks. If we decide to continue using the new design of slope, it will be carried on through toe wall and rain simulation testing.
