Malda Sadar subdivision covers both the Barind Tract and the Diara, two of the three physiographic subregions of the district.

The Barind “is made up of the ancient alluvial humps that are remnants of old riverine flood plains that remained unaffected subsequently by inundation and renewed silting.” It forms an upland slightly higher than the surrounding areas and extends beyond the borders of the district.

“The Diara is a relatively well drained flat land formed by the fluvial deposition of newer alluvium in the transitional zone between the Barind upland and the marshy Tal tract.
