Spectral water indicesSpectral water indices, machine learning (MLMachine Learning (ML)) classifier, parametric image classification, and field parameters-based approaches were adopted for this. Artificial neural network (ANNArtificial neural network (ANN))-cellular automata (CACellular Automata (CA)) was applied for areal prediction of wetlandWetland area. WetlandWetland maps were produced using different approaches. Normalized Difference Water Index (NDWINormalized Difference Water Index (NDWI)) predicted that in post-monsoon 2000 (pre-dam), wetlandWetland area was 1680 km2 which was reduced to 802 km2 in 2013 (post-dam) and continued to decline over progress of time.
