Comparing flat and dome shaped drain covers.
The results show that the raised dome shape drain cover was more effective in stopping the debris along its perimeter while the raised center of the dome was unblocked for water to flow through. However, the flat drain cover was completely clogged by larger debris . Only the water mixed with soil was able to flow through the flat drain cover without clogging.
