The area has a slope from the west to the east. There are some badlands in this region. The Sinhati Badlands are located 4 km northwest of Bishnupur town in the Sinhati area of Bankura district.

Ganges delta The Ganges Delta covers the entirety of Nadia, Kolkata, North 24 Parganas, and South 24 Parganas districts, and the eastern half of Murshidabad district. The Ganges passes through this vast area and divides into three distinct parts: the old delta, the mature delta, and the active delta. The old delta consists of the districts of Murshidabad and Nadia. The formation of delta is complete and the rivers here are heavily silted and many have even dried up over time. Silted rivers, swamps, beels, and oxbow lakes form the area. This area is also known as Bagri region. The districts of Kolkata and North 24 Parganas form mature delta region. The rivers are slow and meandering and frequently shift their courses. Swamps, beels, and oxbow lakes characterise the scenery. The district of South 24 Parganas is known to be the active delta of the Ganges, where the formation of the delta is still an ongoing process. Agro-climatic groups Depending on soil and climate variations, West Bengal can be divided into six broad divisions: The hill region in the north The Terai and Teesta alluvial region of North Bengal The laterectic, red and gravely undulating region in the west The coastal alluvial region in the south The Gangetic alluvial region in the east The Vindhya alluvial region in the centre Rivers The Ganges enters West Bengal near Rajmahal and then flows in a southeasterly direction. It divides in two near north of Dhulian in Murshidabad district. One branch enters Bangladesh as the Padma (or Pôdda), while the other flows through West Bengal as the Bhagirathi and Hooghly River in a southern direction. The Bhagirathi-Hooghly is the main river in West Bengal, and flows past some of the important cities like Murshidabad, Baharampur, Nabadwip, Chinsura, Chandannagar, Srirampur, Howrah, Kolkata, Diamond Harbour, and Haldia.
