A major portion of Chandannagore subdivion is part of the Hooghly-Damodar Plain, the agriculturally rich alluvial plains lying between the Hooghly and the Damodar. The narrow strip of land along the Hooghly is part of the Hooghly Flats. The entire area is a part of the Gangetic Delta. The Hooghly is a tidal river and has a high west bank. The Portuguese, the Dutch, the French, the Danes and the British dominated industry, trade and commerce in this area for more than two centuries, and as a result the Hooghly Flats is highly industrialised.
