Iman Shafii, a Ph.D. candidate in the Civil Engineering Department, has been conducting erosion tests on soil samples collected in areas affected by Hurricane Harvey. The data is used to assess the erosion impact on the coast and to find ways to prevent future disasters.
Normally, equipment is used to collect test samples as far as 50 feet below the surface. However, equipment was not available due to Hurricane Harvey and test samples had to be collected by hand.

Portions of the original test samples are placed in bags and stored for further testing.

Two small portions of the original sample are placed in a furnace in order to remove all of the moisture in them. This is done to determine the amount of moisture in the sample.

The EFA (Erosion Function Apparatus) method is one of the tests conducted on the test samples.

During the EFA test, water flows over the sample, slowly eroding the sample.

Iman Shafii periodically checks the sample, recording data, ensuring that it remains flush, and making changes to the flow of water.

Once the test has been conducted, a large portion of the sample will have been eroded away.
