Description |
Reliable information on spatial extent, distribution and severity of waterlogging problem is one of the prerequisite to identify appropriate management strategy for the waterlogged areas. Therefore, a study about the mapping and management strategy for the waterlogged area was carried out for Rohtak district of Haryana, India. The major objectives of the study were to develop an appropriate mapping strategy for the identification of water logged areas and subsequent identification of appropriate strategy for the management of water logged areas. IRS – 1D, LISS-III satellite data acquired on March 6, 2010 was used to identify surface water logged area as well as toupdate different topographical features digitized with the help of SOI toposheets. Water table depth and water quality maps were also prepared using data from different sources. 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. It was suggested to use digital image processing, rather than visual inspection of satellite imagery, to identify surface waterlogged areas. In general, the existing surface drains in the study area were found to be quite effective in controllingboth surface and subsurface waterlogging problems in thevicinity of the drains. Depending on the quality and depth of groundwater encountered in different regions of the study area, specific management strategies were identified. The identified strategies included surface drainage system, efficient irrigation system, reduction in canal water supply, conjunctive use ofcanal water, groundwater and rainwater, introduction of salt tolerant crops, plantation of highly transpiring trees, planned leaching of salts and fish farming with saline water. |
