**4.1 Soil core test box**

The soil core test box consists of water tight (leak free) container which holds the soil core specimen. The core is made up of wood that is capable to hold soil at a desired angle of the specimens. It includes gutter which is a runoff ramp for the routing of the soil and water that are washed out from the container to the bucket without spilling out. The dimensions are shown earlier in Fig. 1. The actual soil core test box is shown in Fig. 2.
