Title

Landscape change detection of Alaibet, Mouth of Narmada River, Gujarat using Geospatial techniques

Abstract

Alia bet is the pear shaped independent land mass (delta ) of the Narmada River located about 25 km west of Bharuch. Among the various bets at the estuary of Narmada River, Alia bet has its own identity. The name is derived from the term ‘AAL ‘means lush green with the grass. Geologically the delta came into existence due to the silt deposition of the Narmada River, prior to debouching its water into Gulf of Cambay of Arabian Sea. The Gulf of Cambay/Khambhat, (GoC), the study area is highly influenced by the tidal currents other than geological and structural set up of the region. In Gulf of Cambay, a large tidal range during high and low tides give rise to strong tidal currents and develops a mechanism of sediment transportation. Interestingly the inverted funnel shape of GoC has large contribution for the sediment deposition in this region. During high tide the tide currents move into the Gulf and encroaches the river mouth whereas during low tide, they move out. This regular phenomena since long period on geological time scale has modified the geomorphological features in this region. Additionally, human interference has too largely played crucial role to alter the land scape. Almost 30 large, 135 medium and 3,000 small dams and related water infrastructure to harness the waters of the Narmada and its tributaries are either planned or constructed or even under construction. With the passage of time, on account of what so ever reason like population growth, industrialization, huge power demand and else factors have changed the river scape along with the landscape of the river basins. Alia bet is also among the highly affected land mass, drastically altered from bet to huge land mass. Using remote sensing images of different time scale and topographical map one can study the changes in geomorphological features. Satellite remote sensing technique has proven to be the paramount tool for studying surficial land features, especially for the inaccessible area or where time variable studies and regional scale studies are carried out. The attempt is made to detect the change in land scape of Alia bet using Geospatial techniques. The Landsat data, LISS-III, LISS-IV, historical Google earth images and -Quantum GIS (GIS) techniques are used here to understand the process, to detect the changes and to analyses the future trend of progression.
