the Engineers. Lack of understanding of the flood <strong>for</strong>ecast has been a major problem faced by the Army in the past,<br />

since they are no acquainted with the commonly used. Hydro meteorological terms and no arrangement of the preflood<br />

training of the concerned CC Engineers corps has so far been made As the flood arrives , units of the Army<br />

move out to their respective areas of responsibility and carry out relief and rescue operations in coordination with civil<br />

administration . A major post flood meeting is held under the chairmanship of E-IN-E to discuss the per<strong>for</strong>mance of all<br />

the flood related agencies with the view to bring about the necessary improvement in future.<br />

3.3.6 Pakistan Commissioner <strong>for</strong> Indus Waters (PCIW)<br />

Pakistan has a unique flood- <strong>for</strong>ecasting problem in the sense that greater part of the flood producing upper catchments of<br />

the Sutlej, Ravi and Chenab rivers lies across the border in India / held Kashmir. Further more a number of control<br />

structure like dams and barrages etc, exist over the rivers across the border with the result that the free conditions are<br />

destroyed making the operation of the rainfall / runoff model extremely difficult. The situation underlines the need <strong>for</strong> the<br />

river flow data from across the border in respect of the important sites over the rivers in India / held Kashmir.<br />

Consequently, an agreement has been signed between the two countries through their respective Commissioners <strong>for</strong> Indus<br />

water which includes a provision to receive from India such river flow and rainfall data as is considered important <strong>for</strong> flood<br />

<strong>for</strong>ecasting in Pakistan.<br />

A number of river flow stations are specified <strong>for</strong> this purpose. Normally once a day the data is received by the Pakistan<br />

Commissioner <strong>for</strong> Indus waters. The data is then passed on to the Chief Met FFD. Frequency of data reception is increased<br />

to six hourly and even to hourly in relation to the prevailing flood situation. Pakistan commissioner <strong>for</strong> Indus waters is thus<br />

responsible to provide to the Chief Met FFD the much needed data from India <strong>for</strong> use in the flood <strong>for</strong>ecasting models.<br />

Many problems have occurred in the past when the India data in respect of river Ravi was passed on to the press which<br />

resulted in the issuance of false alarm to the public. This is because large-scale attenuation of the flood wave occurs<br />

between Madhopur (India) and Jassar due to the physiographic characteristic of the catchments and the river bed.<br />

Incidences are not uncommon when the flood peak at Jassar is reduced to 1/4 th of its size at Madhopur.It has thus decided<br />

that the India data as received through the Commissioner <strong>for</strong> Indus waters must not be made public to avoid false alarm<br />

arising out of the wrong interpretation of the data. .Leakage of this data to the press must be specially guarded since the<br />
