| Zusammenfassung |
| Tsunami impact study has been undertaken along Chennai coast starting from
Pulicat to Kovalam. The study area Chennai coast is mainly devoted to
prepare large scale action plan maps on tsunami inundation incorporating
land use details derived from satellite data along with cadastral data using
a GIS tool. Under tsunami inundation mapping along Chennai coast an
integrated approach was adopted to prepare thematic maps on land use/land
cover and coastal geomorphology using multispectral remote sensing data. The
RTK dGPS instruments are used to collect elevation contour data at 0.5 m
intervals for the Chennai coast. The GIS tool has been used to incorporate
the elevation data, tsunami inundation markings obtained immediately after
tsunami and thematic maps derived from remote sensing data. The outcome of
this study provides an important clue on variations in tsunami inundation
along Chennai coast, which is mainly controlled by local geomorphologic
set-up, coastal zone elevation including coastal erosion protection measures
and near shore bathymetry. This study highlights the information regarding
most vulnerable areas of tsunami and also provides indication to demarcate
suitable sites for rehabilitation. |
