component analysis image. Once again, the IHS image has 
given clear picture of submerging rocky beach in Manori 
region. These images have given distinct tonal and textural 
contrast between sandy and rocky beaches. When analyzing the 
coastal geomorphology for different periods, the portion of 
sandy beach is proportionately increased from 1966 to 1996. 
3.2 Land use/ Land cover Change 
The Manori creek region in Mumbai coast has different land- 
use/land-cover categories, like vegetation, mangroves, 
mudflats, saltpan, rocky outcrop area, sand and water bodies. In 
which, mangroves is one of the most valuable coastal resources 
in this region. Naturally, wetland ecosystem and mangroves 
provide a nursery and breeding ground for many fish and 
prawn species. It also protects against coastal erosion and 
provides habitat for some protected species of birds and 
animals. Hence, it is necessary to study and monitor the 
wetland ecosystem in Manori creek region. An attempt has 
been made to interpret the land-use/land-cover in Manori creek 
region with the help of visual and digital image processing of 
satellite data.

From the topographic sheet, it is able to identify the mudflats, 
high and low tide regions, urban built-up areas, vegetation, and 
water bodies (Fig 3). However, remote sensing data has given 
more refined information on land-use /land-cover. For example, 
the visual interpretation of Landsat TM data (1988), the 
vegetation, barren/ fallow land, sandy beach, wetland, saltpan, 
water body in creek are distinctly demarcated (Fig 4). The 
processed output is given still more refined information on 
boundary condition between different land-use/land-cover 
categories. The FCC of IRS-1C satellite data has given clear 
information on mudflats with and without mangroves, 
vegetation on rocky and non-rocky portion, saltpan, barren 
land, fallow land built-up areas and water bodies (Fig 5). The 
IHS of IRS-1C has given optimal boundary condition between 
different land-use/land-cover categories e.g. the mudflats 
shown in olive green colour, against the rocky areas with pale 
bluish green colour. Similarly clear boundary conditions are 
also exit between fallow land and coastal plains.

After interpreting the land-use /land-cover categories from 
remote sensing data an attempt has been made to correlate the 
various geomorphic units and land-use/land-cover categories. 
Mudflats mostly covered by mangroves and saltpan. Urban 
built-up areas cover the majority of the coastal plain. Currently 
significant coastal low lands areas are under fallow land.
