    Floods & Landslides Floods & Landslides Presentation Transcript

    • RS & GIS ApplicationsFLOODS & LANDSLIDES Lokhaze Ali
    • Hadith• Allahs Messenger (peace be upon him) said, "When Allah created the Earth it began to oscillate, so He created the mountains, ordered them onto it, and it became steady. The angels marvelled at the strength of the mountains and asked their Lord whether there was anything in His creation stronger than the mountains. God said, "Yes; iron is stronger than mountains (rocks), for it breaks them." The angels said, "O Lord! Is there anything of Thy creation stronger than iron?" God said, "Yes; fire is stronger than iron, for it melts it." And the angels said, O Defender! Is there anything of Thy creation stronger than fire?" God said, "Yes; water overcomes fire; it kills it and makes it cold." Then the angels said, "O Lord! Is there anything of Thy creation stronger than water?" God said, "Yes; wind overcomes water: it agitates it and puts it in motion." They said, "O our Cherisher! Is there anything in Thy creation stronger than wind?" God said, "Yes, the children of Adam, giving alms; that is, those who give with their right hands and conceal if from their left, they overcome all."

    • Linked: Extreme Russian Fires and Pakistan Floods• Two of the most destructive natural disasters of 2010 were closely linked by a single meteorological event, even though they occurred 1,500 miles (2,414 km) apart and were of completely different natures, a new NASA study suggests. The research finds that the same large-scale meteorological event -- an abnormal Rossby wave -- sparked extreme heat and persistent wildfires in Russia as well as unusual downstream wind patterns that shifted rainfall in the Indian monsoon region and fueled heavy flooding in Pakistan.• http://www.youtube.com/watch?v=UroG2DS3xsg

    • Noreaster Floods - GOES Satellite• This video of GOES satellite imagery was created from data compiled March 8 through 16, 2010. It shows flooding rains from a Noreaster that soaked the U.S. Northeast.• http://www.youtube.com/watch?v=CHIF VHhTZPA

    • Global Landslide Risks • Reduce the loss of life from landslides • Global, satellite-based early-warning system • Landslide-prone regions, as shown in this image • Coarse soil, land cover that was inadequate to stabilize the surface, and/or steep mountains • The regions that have the highest risk of landslides are salmon pink • Areas of moderate risk are lavender • Regions with a slight risk are pale blue • Areas where landslides occurred between 2003 and 2006 are marked with black dots on this map
    • Landslides-What they are & their causes• http://www.youtube.com/watch?v=JrV4 uCVwmfk&feature=related
    • Landslide Evaluation
    • Landslide in Pakistan
    • ANALYSIS AND PREDICTION OF LANDSLIDESIN GIS (GEOGRAPHIC INFORMATION SYSTEMS) • Most landslide potential models determine terrain instability by combining slope maps with soils data, then selecting from the resultant soil/slope categories the combinations that are rated for severe erosion potential. Vegetative cover considerations extend the model. When available, maps showing historic landslide sites are added for both establishing and testing landslide potential.
    • SHALSTAB Landslide Model • SHALSTAB landslide potential model works best with detailed elevation data. A Digital Elevation Model (DEM) spatial resolution of 10 meters is desired. Raster-to- Vector procedures are used to convert base maps to project grid and raster-to-vector procedures are used to output a model.
