(a) Piezometric head or pressure head

(b) Velocity head

(c) Position head

(d) All of the mentioned

The question was posed to me in examination.

The above asked question is from Two Dimensional Flow : Laplace Equation topic in chapter Seepage Analysis of Geotechnical Engineering I

Answer 1

Right option is (d) All of the mentioned

For explanation I would say: When water flows through a saturated soil mass, the total head at any point in the soil mass consist of i)piezometric head or pressure head ii) the velocity y head iii)the position head.
