An Innovative Approach to Delineate and Differentiate Clear and Turbid Water Ponds in Indian Sundarban Area Using Sentinel-2 MSI Data

Pond water is the main source of irrigation in Sundarbans area West Bengal. The serious issues faced agricultural lands and ponds are due to salinity. As salinity cannot be detected on high scales through satellite images, this study remotely sensed turbidity has been compared studied with laboratory-measured high-resolution Sentinel-2 MSI data optimum bands for quality detection have used study. small were not by conventionally indices, as surrounded homestead vegetation. Hence, a new index called Probability Spectral Index (PPSI) was formulated decision tree algorithm delineate all ponds. Turbidity indices over extracted classify them into three classes, clear, turbid highly turbid. From field accuracy assessment, one outperformed segregating an overall 83.3%. It also found that inversely proportional only when value greater than 100 NTU. total estimated pond (average 3 seasons) Sundarban region 471.66 km2.
