new pits are 300 feet apart. If all the test pits show sand and gravel, it is assumed that the entire area, 300 feet by 300 feet contains sand and gravel. Test pit E is excavated but no sand and gravel are found. This means the gravel deposit ends somewhere between B and E. It can be assumed the gravel material stops halfway, or in this case, 150

The primary difference between sand, silt, and gravel is the size of their particles. Silt is finer than sand, with particles less than 0.0625 mm, often giving it a smoother feel. Gravel, conversely, is coarser, with particle sizes above 2 mm. This difference in size results in distinct physical characteristics and applications for each material.
On the right above is a better way to do it. Again we have a pipe running from above the ground to the water bearing sand but there is also a gravel pack at the bottom of the pipe. This gravel pack provides a much bigger sand surface area for the water to enter. Water travels much easier and faster through gravel than it does through sand.
among different sizes within the sand and gravel fractions is small relative to that between the sand and gravel. The limiting case, in which the transport rate of all sizes (scaled by their proportion in the bed) is identical, is the condition of equal mobility defined by Parker et al. [1982b]. Similar
