The eastern part of the Nagpur country and the Chhattisgarh plain, comprising the Mahanadi basin, form the great rice tract of the province, its heavy rainfall and hard yellowish soil rendering it excellently adapted for the growth of this crop.
The middle and eastern divisions of the district, forming the south-western part of the Mahanadi delta, consist entirely of alluvial plains, watered by a network of channels through which the most southerly branch of that river, the Koyakhai, finds its way into the sea.
The District of Ctttack lies in the centre of Orissa, occupying the deltas of the Mahanadi and Brahmani, together with a hilly tract inland.
The best harbour in Cuttack district is at False Point, on the north of the Mahanadi estuary.
The bay receives many large rivers, of which the most important are the Ganges and Brahmaputra on the north, the Irrawaddy on the east, and the Mahanadi, Godavari, Kistna and Cauvery on the west.
