Southwest monsoon influences the water quality and waste assimilative capacity in the Mandovi estuary (Goa state, India)

The monsoon-dominated Mandovi estuary is located in Goa state – a global tourist destination along the centralwest coast of India. In addition to factor analyses of water quality data, the water quality index (WQI), trophic state index (TSI) and percentage of freshwater volume in the estuary are cal...
