A GIStopology to detect coastal groundwater Potential zones and variation of sea water temperature along west coast of Karnataka

Abstract

Due to increase in atmospheric greenhouse
gases, the coastal water temperature is slightly
increasing with time period. For this coastal sea
water surface temperature (SST) approach, MODIS
has some limitations due to 1km resolution. However,
in this work Landsat thermal bands had used for
calculating SST. The study area of this investigation
comprises coastal zone of Arabian Sea from
Nethravathi to Udupi and the data obtained is
Landsat8 OLI/TIRS imagery. In this paper, we
mainly focussed on identification of potential zones of
ground water in a coastal river basin (Pavanje in
Karnataka state) and variation of SST in coastal
area. Thematic layers like soil, slope, rainfall
distribution, land use/land cover, stream density is
created with assigned weightage which will support
in identification of groundwater potential zones. SST
varies from 22.5 to 41.4 degree Celsius temperature
and groundwater potential zones is extracted by
integrating the thematic layers for the study area.
 

Keywords: Thematic layers, Groundwater potential zones, Sea Surface Temperature along Coastal zone.
