A Study on Moyna Basin Water-Logged Areas (India)‎ Using Remote Sensing and GIS Methods and Their Contemporary Economic Significance

Abstract EN

The prime objective of this paper is to identify and map the water-logged areas within Moyna basin, India, and to explore their contemporary economic significances.

The Landsat 5 TM, ASTER data, and topographical sheets have been taken into consideration with field observations.

Maps on relief, slope, canal density, embankments, a supervised classification of the study area and then NDVI, NDWI, and modified NDWI or NDMI have been prepared here.

At Moyna, the piezometric surface ranges from five to ten metres below the ground level.

The percentage of clay particles is high throughout the surface soil.

The total rainfall is nearly 1400 mm and most of it happened during the monsoon period.

Two well-marked depressions are observed there within the basin and the nearly central one is wide and is clearly identified from the relief map also.

Problem of drainage congestion there accelerates the onset of water-logged situation.

In general, water-logged areas are not suitable for humans.

People once were worried about the water-logged environment due to underwater scenario of low-lying agricultural fields for a certain period, but today local people are taking this environmental condition as an opportunity for fishing activity and thus they are becoming economically benefitted as well.
