Evaluation of a Drainage Project through Hydro-salinity and Groundwater Quality Mapping using GIS and Satellite DataPublished by the American Society of Agricultural and Biological Engineers, St. Joseph, Michigan www.asabe.org Citation: Paper number 022059, 2002 ASAE Annual Meeting . (doi: 10.13031/2013.9838) @2002Authors: Nasir M. KHAN, Yohei SATO, Sho Shiozawa Keywords: Drainage, Hydrosalinity, Groundwater quality, GIS, Remote Sensing, SCARP, Reclamation, Agriculture, Planning Degradation due to hydro-salinity in the Indus basin semi-arid irrigated areas of Pakistan has deteriorated the vast productive agricultural land. The present approach was an effort through various GIS and RS techniques using IRS-1B LISS II data along with field data/maps and soil-water quality indicators to provide information about the cause, extent and magnitude of the problem in a drainage project area. Strong relationship has been found between hydro-salinity prone areas and drainage network. Shortage of irrigation water has been found the most limiting factor to solve the twine menace. About 61.7 % of hydro-saline area occurred in hazardous groundwater quality and high watertable depth. The hazardous groundwater quality getting dominant, deteriorating the area by inducing salinity-sodicity, required immediate special reclamation and management measures. Saline areas mostly following the trends of occurrence of brackish groundwater quality and high watertable. The satellite (IRS-1B) data with adopted methodology has been found promising in potential to map hydro-salinity with few remote sensing indicators and field data. (Download PDF) (Export to EndNotes)
