Floods are very common in all the province of Pakistan and flooding is themost dangerous natural disasters and the recent destructivefloods have shown its severeness in Pakistan. Monsoon rainfalls are the main cause of floods in the river Indus Basin and these floods throughout the country have caused major economic loss of lives, properties and agricultural crops. International relief organizations and Pakistan’s government have spent a lot of money and other resources on relief activities since the first devastating flood of 1950. Every year floods come in Pakistan, they destroypublic and individual’s buildings, infrastructure, bridges, thousands of vehicles, kill thousands of people and disrupt millions of people. As a result of frequent floods, a number of ordinances and acts are shaped for the flood management by the government but in vain, frequent flood disasters data show no major reduction in floods and damage ratio due to floods. There is a lack of flood hazard and crisis management institutions and lack of depth data and information system to control frequent floods in Pakistan.
Thus there is a great need of Digital Flood Inundation Maps (DFIM) for any flood management plan. It can be very powerful tool forflood response and mitigation. DFIMs can keep all records of minor and major floods and help emergency staffs and decision-makers visualize wherefloodswill affect most thus by using DFIMs tool flood warning, preparedness and relief operations and evacuation and rescue actions can be enhanced that will tell accurately floodwater seriousness, depth, momentum over the land surface thus the people, government and non-government institutions can take timely operation and the government can take public safely decisions and operations before and during floods events.
