VISUAL INTERPRETATION METHODS OF LAND USE/LAND COVER CHANGES & ANALYSIS USING GIS & REMOTE SENSING TECHNOLOGY: A CASE STUDY OF GOMUKHI RIVER BASIN OF TAMILNADU, INDIA
International Journal of Advanced Research
The proper watershed or river basin development of a management strategy requires accurate measurement of the past and present land use/land cover changes of study area. These land use/land cover parameters determine the hydrological and ecological processes taking place in with a watershed area. This study done by satellite image of Landsat -7ETM+ in 2006, 2010, 2016 using Arc GIS 10.1 software and update the year of 2016image is using Geo Eye data. The Gomukhi river basin classified into NRSC
... lassified into NRSC level-2 land use /land cover classes Viz. crop land, fallow land, plantation, dense forest ,open forest ,degraded forest ,land with scrub, land without scrub, rivers/lakes(water bodies),settlement(Built Up land),and barren rocky. The overall analysis of study area the years of 2006 to 2016 land use land cover classes of viz., crop land (11.95%), plantation (1.57%) and dense forest (0.09%) is decreasing. And also fallow land (9.64%), open forest (0.47%), degraded forest (0.70%), land with scrub (1.41%), land without scrub (0.86%), rivers/lakes (0.15% and settlement (1.48%) respectively, barren rocky no changes accruing the study area. The land use /land cover classes transformation posed a serious threat to river basin or watershed resources. Here proper river basin planning and management is required or else these land use /land cover resources will soon be lost and no longer be able to play their role in socio economic based sustainable development of the study area.
