The Kaveri River, which is the fourth biggest river in India, is experiencing a significant increase in urbanisation and construction along its course and in the areas surrounding it. Apart from the diminishing natural flow resulting from the faltering monsoonal supply and the building of big, medium and small dams, the widespread extraction of sand from its channel bed places significant strain on its inherent fluvial processes. The environmental integrity of this significant river has deteriorated due to a number of factors, including changes in the textural parameters of the stream bed sediments, a reduction in the channel's carrying capacity, the development of channel-in-channel physiography, and extensive vertical accretion of sediments within the channel. This paper aims to record the decline in natural fluvial dynamics brought about by human interference and a deficiency of information necessary for accurate comprehension of environmental management and the preservation of the fluvial system.
