主 题：waterlogging salinity Ganga plain digital earth groundwater resources digital data
摘 要：In the present study,the multi-temporal satellite images of IRS P6 LISS III were used to map waterlogging dynamics over different *** area of 594.36 km2(6.75%)and 4.17 km^(2)(0.04%)was affected by surface waterlogging during pre and postmonsoon season,*** average annual groundwater level fluctuations were calculated using 18 years(1990-2007)pre and postmonsoon groundwater level data to identify the areas which are under groundwater induced waterlogging *** soil map clearly indicates that salinity and sodicity exhibit the highest severity and occur in areas with shallow groundwater *** hydrogeomorphical units mapped using IRS P6 LISS III satellite images are flood plain,alluvial plain,paleochannels,and oxbow *** study revealed that 44.65%areas have very good to excellent groundwater *** litholog data clearly indicate an alternating sequence of clay and sand in which deep aquifers made up of coarse sand would be best suited for adequate water supply and good groundwater *** integrated study utilizing digital spatial data pertaining to waterlogging,soil salinity,water level fluctuation,and lithological variation proved that planning of any surface and subsurface water resources development activity should be taken up after assessments of said parameters.
