2. Select a datum. Let us choose the downstream water level as the datum.

3. There are two method to determine the total hydraulic head loss,h;

i) total hydraulic head loss at point p, h p =   =  

from upstream)

ii) total hydraulic head loss at point p, h p =

  (counted potential drop from downstream)

Where;

H –  head difference

(driving seepage)

 Ne –  total no. of

equipotential drops

n p –  no of equipotential

drops at any points (eg:

at point P)
