Title: Trends Analysis of River Bank Erosion at Amuriver Using Remote
Sensing and GeographicInformation System
The study examined the trend of river bank erosion from 2000-2014, detected shoreline change and predicted the rivermigration from 2014-2030 in Qarqin district. The study is the first of its kind as no previous study has been done before. In this research, landsat images and very high resolution (IKONOS, Quickbird and Pleiades) images were used.. The image classification was done from 2000-2014. Remote Sensing and Geographic Information system applications were used to categorize eroded area and identify shorelines change locations. Furthermore,liner extrapolation technique was employed to predict river movement from 2014to 2030 at five year intervals. The study found that the river movement wastoward Afghanistan side i.e., south. The land lost from 2000 – 2014 was estimated at 5074 hectares in total. It was calculated as 1984 hectares from 2005 – 2010 a major increase noticed from other periods which were 1410 hectares from 2000-2015 and 1680 hectares from 2010-2014. The shoreline was demarcated and categorizedinto three zones i.e., lower as moderate eroded zone, central as high erodedzone and upper as lower eroded zone. The predicted land lose from 2014-2030 was calculated 6160 hectares due to river migration toward Afghanistan side primarily because of lack of proper management. The study willbe useful to government agencies responsible for river bank erosion managementin taking decisions. Based on trend analysis and shoreline migration, the study has concluded that eroded area by river and those were calculated from the historical data, for the better understand shoreline changes and projected future river locations.
