espective areas to ensure that the structures ( bunds , barrages , spurs etc ) are in satisfactory stae of maintenance .Discrepancy , if any is brought to the notice of the relief commissioner and PIDA. Sometimes joint inspections with PIDA are carried out to save time Pakistan Army’s major flood related starts after the flood occurs. An officer of the 4 Corps engineers is placed on duty in the flood warning center to keep a close watch on the flood situation. All flood forecasts and warni9ng are communicated to the CC Engineers 4 Corps in time to be transmitted to the D.G. Engineers and all other CC Corps of c:\documents and settings\administrator\desktop\cd material nust\international training workshop\session 5\2_sop pmd_51 pages.doc
the Engineers. Lack of understanding of the flood forecast has been a major problem faced by the Army in the past, since they are no acquainted with the commonly used. Hydro meteorological terms and no arrangement of the preflood training of the concerned CC Engineers corps has so far been made As the flood arrives , units of the Army move out to their respective areas of responsibility and carry out relief and rescue operations in coordination with civil administration . A major post flood meeting is held under the chairmanship of E-IN-E to discuss the performance of all the flood related agencies with the view to bring about the necessary improvement in future. 3.3.6 Pakistan Commissioner for Indus Waters (PCIW) Pakistan has a unique flood- forecasting problem in the sense that greater part of the flood producing upper catchments of the Sutlej, Ravi and Chenab rivers lies across the border in India / held Kashmir. Further more a number of control structure like dams and barrages etc, exist over the rivers across the border with the result that the free conditions are destroyed making the operation of the rainfall / runoff model extremely difficult. The situation underlines the need for the river flow data from across the border in respect of the important sites over the rivers in India / held Kashmir. Consequently, an agreement has been signed between the two countries through their respective Commissioners for Indus water which includes a provision to receive from India such river flow and rainfall data as is considered important for flood forecasting in Pakistan. A number of river flow stations are specified for this purpose. Normally once a day the data is received by the Pakistan Commissioner for Indus waters. The data is then passed on to the Chief Met FFD. Frequency of data reception is increased to six hourly and even to hourly in relation to the prevailing flood situation. Pakistan commissioner for Indus waters is thus responsible to provide to the Chief Met FFD the much needed data from India for use in the flood forecasting models. Many problems have occurred in the past when the India data in respect of river Ravi was passed on to the press which resulted in the issuance of false alarm to the public. This is because large-scale attenuation of the flood wave occurs between Madhopur (India) and Jassar due to the physiographic characteristic of the catchments and the river bed. 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 that the India data as received through the Commissioner for Indus waters must not be made public to avoid false alarm arising out of the wrong interpretation of the data. .Leakage of this data to the press must be specially guarded since the c:\documents and settings\administrator\desktop\cd material nust\international training workshop\session 5\2_sop pmd_51 pages.doc
