ABSTRACT : |
Waterlogging is one of the major problem of land degradation processes. Reliable and accurate mapping of areas affected by these processes with their location and extent can be extremely useful in chalking out suitable water management strategies and also to undertake remedial measures to prevent their advancement. The study was carried out for Rohtak district of Haryana, India. For this study IRS – 1D, LISS-III satellite data acquired on March 6, 2010 was used to identify surface water logged area as well as to update different topographical features digitized with the help of SOI topo sheets. Water table depth and groundwater quality maps were also prepared using data collected from different sources. GIS environment was used to prepare and overlay different thematic maps and to extract the desired information. Based on satellite imagery, about one per cent of the study area was found to be affected by surface waterlogging during the pre-monsoon period of 2010. Management strategies were suggested depending on the nature of the problem i.e. surface or sub-surface waterlogging as well as depth and quality of groundwater.
