main central canal and an east and west boundary main 

 drain divide the property into east and west "kisms" 

 each containing 2,500 feddans. The kisms are then 

 divided by canals and drains into "hods" 2,000 m. x 

 1,000 m. of 500 feddans each. Hods are subdivided into 

 " hoshays," 1,000 m. x 800 m., of 70 feddans each. The 

 hoshays are further subdivided by a small irrigating 

 channel down the centre of each and drains at right angles 

 to it and 50 metres apart, into "gattas." The unit is 

 then the gatta 150 x 50 m. surrounded on all sides by a 

 small bank thrown up in excavating the drains and these 

 gattas contain one and three quarter feddans each. 



The following diagrams show the arrangement of canals 

 and drains.
