How Canal Alignment should be done ?

Canal Alignment should be done in such a way that

  1. It should serve the entire area proposed to be irrigated.
  2. Cost of construction including cross drainage works should be minimized.
  3. A shorter length of canal ensures less loss of head due to friction and smaller loss of discharge due to seepage and evaporation, so that additional area may be brought under cultivation.
  4. A canal may be aligned as a contour canal, a side slope canal or a ridge canal according to the type of terrain and culturable area.
  5. A contour canal irrigate areas only on one side of the canal. Continue Reading »

Warabandi system of water management

MEANING OF WARABANDI

WARABANDI is a rotational method for equitable distribution of the available water in an irrigation system by turns fixed according to a predetermined schedule specifying year, day, time and duration of supply to each irrigator in proportion to the size of his landholding in the outlet command.

The term WARABANDI means turns (Wahr) which are fixed (bandi). Continue Reading »

Sub Base Course of Rigid Pavement

This is the layer (or layers) under the base layer. The properties and function of this layer are similar to those under flexible roads/pavements. A sub-base is not always needed and therefore may often be omitted. Continue Reading »
