ABSTRACT

Recurring floods in the low lying coastal areas is often threatening human life and their activities. As strong economic activities are operating in the coastal zone, there is a need to minimize the threats from natural hazards. Coastal geomorphology and the processes acting on them play a vital role in determining the severity of the coastal hazards. Satellite Remote Sensing with its intrinsic advantages has become a decisive tool to monitor natural disasters at local, regional and global scales. The synoptic and temporal coverage of satellite images facilitate valuable information useful in the assessment, monitoring, and management of coastal resources and natural hazards management. The present work deals with Krishna river deltaic region in parts of Krishna, Guntur, Prakasam, and West Godavari districts of Andhra Pradesh, India. This delta represents one of the most fertile regions of South India, and is highly prone to floods & cyclones. The extents of inundation during three different events are extracted, and geomorphic setup of the delta is analysed. Finally, the multi seasonal land use/land cover (LULC) is mapped. The flood response to geomorphic setup and coastal land use patterns is discussed.
