In the two-peg test of a dumpy level, the following observations are taken: with level setup at M (midway between A and B), the rod readings on A and B are 1.155 m and 1.770 m, respectively. With level at P, the rod reading on A is 2.423 m and that on B is 2.999 m. If point P is located 1.67 m from A along the extension of line AB and 76.910 m from B, the correct rod reading (d') on the far rod for a horizontal line of sight (with the level still setup at P) should be Select the correct response: • 3.039 m • 2.424 m O• 2.959 m · 2.422 m •2.999 m

Principles of Seepage

In hydrology, when water flows down in a pore or crack of unsaturated soil due to gravity, the deep layer of soil is called seepage. It is the slow movement of water in the soil layer. Seepage is mainly found near hydraulic structures and is responsible for the stability of earthen-type hydraulic structures.
