SUBMERGENCE AREA
BACK  «  TOP  »  NEXT

Water spread area was assessed by digitizing the contour of 83 m. Contours of 80 and 100 m were digitized using the Survey of India topographic maps of Scale 1:50000. Interpolation of these provided 83 m contour and overlay of Figure 5 with the region corresponding to 83 m contour provided the extent of submergence, which is about 1882.96 hectares. Table 3 lists various land uses in the submergence area. Forest constitute the major portion (46.66%) followed by areca plantation (27.75%), rubber plantation (6.53%) and agriculture (1.87%).
