Due to anthropogenic activities and climatic variability, floods have been raised lately in several regions worldwide. The resulting impact of floods on environment is often harmful. This is particularly applicable to under developed countries like Pakistan, the country which is known for dry climatic conditions, and it became known region for such natural hazards and calamities. The present study showed an effective method of using Geographical Information system (GIS) for generation of expected flood hazard areas mapping from the available data sets. The study conducted flood analysis by using Remote Sensing and GIS technique along River Chenab in the vicinity of Sialkot, Gujrat and some area of Wazirabad Pakistan, during flood event that occurred in 2014. For this purpose, the satellite data used were two Landsat 8 images (L8 OLI/TIRS), the first one acquired on 25 August 2014, about 10 days before the flood and the second one acquired on 10 September 2014, four days after the event used as the main input to assess the damages with the help of GIS analysis tools. Different GIS and remote sending techniques were applied for the analysis of flood affected areas in Pakistan.
