a. Out of the above, Chashma, Sukkur and Kotri Barrages received<br />
and passed higher peaks than their designed discharge capacity, assuming<br />
Sukkur’s reduced capacity, of 1.1 million cusecs.<br />
b. Another unusual feature noted from the flood flows throughout the<br />
Indus route, from Besham in northern hills to Kotri plains in Sindh was the<br />
abnormal variation from the historical record as self evident from the<br />
following table:-<br />

REMARKS<br />
The Flood<br />
informations were<br />
regularly<br />
disseminated to<br />
Flood Centre of<br />
PMD on hourly<br />
basis along with<br />
Irrigation<br />
departments of<br />
Punjab, Sindh and<br />
Federal Flood<br />
Commission<br />
Islamabad<br />
8<br />
Note : During Flood 2010 the Lag Time which were measured before became unvalid due to contribution (gains) in some reaches<br />
(rain and local Hill torrents) and heavy losses in some reaches (Breaches in river Bunds)<br />
