Tail-end problems[edit]
R.Chambers ^[16] cites authors who have reported tail-end problems. Examples are:

• 
  The old Sardar canal project in the state of Gujarat, India, was designed with an irrigation intensity of 32%, but at the upstream part the delivery was at an intensity of 42% (i.e. 131% of the design norm) and at the downstream end it was only 19% (i.e. 59% of the norm), although the project aimed at protective irrigation with equal rights for all.
  
• 
  The Sardar Sahayak Pariyojana irrigation project, an extension of the Sardar canal project with 1.7 million ha, the head farmers received 5 times more water than the tail-enders, although the project was designed for equal distribution of the scarce water.
  
• 
  The Ghatampur distributary canal in the Ramganga irrigation project in the state of Uttar Pradesh, India, delivered an amount of water equal to 155% of the design discharge to the Kisarwal district canal near the head of the distributary and only 22% to the Bairampur district canal at the downstream end.
  

The Ibrahimiya irrigation canal near Minya, Egypt
Also in Egypt, in 1984, considerable differences in the water distribution over the canal systems have been reported:^[17]

Lateral canal	Water supply in m³/feddan *)
Kafret Nasser	4700
Beni Magdul	3500
El Mansuria	3300
El Hammami (upstream)	2800
El Hammami (downstream)	1800
El Shimi	1200

*) Period March 1 to July 31. 1 feddan is 0.42 ha. Data from : Egyptian Water Use Management Project (EWUP).^[18]
