SWAP
Material test 3_Analysis This test had a 50-50 sand-clay version which was 3cm thicker than the previous versions with a total thickness of 5cm. The lower part of the sample was affected the most by the force of water. Within the first nine hours of the experiment, major changes were visible in this part. The test was stopped after 41 hours, due to stagnation of the erosion effect. A deep cavity was created at the dripping point. Water that gathered in the cavity absorbed the force of water, thus maintaining the depth of the cavity after it reached a depth of 3cm. This depth of the cavity will be directly proportional to the force of water.
Embedded voids
Observation: In the beginning water dropped on the surface and flowed normally. After certain time the surface eroded thus changing the movement of water creating a constant feedback with erosion.

3 - MATERIAL RESEARCH
This sample was programmed with an integrated void. To keep the surface flat, this void was then filled with granulate sand which can easily be removed by water.
