Abstract
Waterlogging and salinity are the dual problem which are mainly found in irrigated area of developing countries like India. Waterlogging causes change in cropping pattern which ultimately leads to inefficient use of land. Geo-spatial techniques were found effective to represent spatial distribution of surface waterlogging of Hisar district as well as selected site (DDUCE-OF) along with field validation. The study was conducted to identify and map the extent of waterlogging and groundwater quality in Hisar district through Geo-spatial techniques and selection of site DDUCE-OF, CCSHAU, Hisar to provide suitable measures for management of waterlogging and salinity. The maps of water table depth and groundwater quality for pre and post monsoon were generated for the years 2013 to 2018. LANDSAT-8 satellite image was effectively used for determining surface waterlogged area which found to be 7.76 percent in Hisar district. Analysis of water table depth maps for both pre and post monsoon of Hisar district generated in GIS environment for the years 2013 to 2018 reveals that in post monsoon area (average 0.80 %) under fully waterlogged ( 4 dS/m) at top layer (0-15 cm) of the soil surface and it was decrease with the depth. Hence suitable measures such as subsurface drainage system, irrigation management, salt tolerant crops, lining of the water conveyance system and water storage tanks are the major management practices suggested for the management of waterlogging and soil salinity at DDUCE-OF, CCSHAU, Hisar.
