The water makes their crops grow. Soft soil and level land of the Indus Plain makes digging of canals easier than in the rugged lands of Balochistan. The canal must not pass through forest, town, village or costly areas reducing the chance of giving heavy compensation. Sediment control structures constructed at the heads of run-of-river irrigation schemes have little effect on the very fine sands and silts that settle in the smaller distribution canals. Always a canal alignment with less cross-drainage work must be chosen. These range from damage to the patient’s clothing, splashing the irrigant into the patient’s or operator’s eye, injection through the apical foramen, and allergic reactions to the irrigant, to inadvertent use of an irrigant as an anesthetic solution (4). Sources of water are limited and to provide irrigation facilities to larger areas, judicious use of available water is very essential. This water was used for drinking, washing, and irrigation. Farmworkers have drowned on the job when accidently falling into canals. Flow of floodwater is hampered which may cause heavy damage to the dam because of mounds of silt which block the flow of water. flow gates, sluice gates, or valves control the flow of water from the source, to the point of use. Irrigation is critical to agriculture in southern Alberta, with water transported through canals. Dangerous droughts can be avoided that expedite economic development.
