HIGHLIGHTS

  • Indus river basin irrigation system plays a vital role in Sindh and Baluchistan of Pakistan.
  • The only cultivable command area is 5.43 Mha in Sindh and Baluchistan which depends on
  • The excess of silt (in the right bank canal of Sukkur barrage) reduces the velocity of water.
  • About 60% less cultivation was observed at Saifullah Magsi Branch Division (border of Sindh-Balochistan).
  • The satellite image based model shows the negligible velocity to the right pocket of Sukkur barrage.

ABSTRACT

Indus river basin irrigation system in Pakistan has three major reservoirs, sixteen barrages, two head works, two siphons across major rivers, twelve inter river link canals and forty four irrigation canals. Average gradient was observed from sea level as flat with rate of 12.5 cm/km (8 inches/mile). Indus provides irrigation water to major portion of Sindh (about 41 %). The total gross commanded area of Sindh and Baluchistan which depends on Indus is 5.92 Mha whereas, the only cultivable command area is 5.43 Mha. The major crops grown in Sindh are rice in Kharif and wheat in Rabi. Besides this, Sindh also produces horticultural crops such as mangoes, bananas, dates and chilies. Sindh has also diversion capacity of 111 billion cubic meter (BCM) which is equivalent to 90 million acre feet (MAF). It was found in the research that excess of silt (in the right bank canal of Sukkur barrage) reduces the velocity of water. About 60% less cultivation was observed in 2018 at Saifullah Magsi Branch Division in the border of Sindh-Balochistan. The satellite image based model shows the negligible velocity to the right pocket of Sukkur barrage.
