The delta consists of the middle course of the Niger River, between the bifurcated Niger and its tributary the Bani, which from here run north towards the desert. The Niger is the longest river in West Africa. Towns such as the river-port of Mopti, Sévaré and Djenné, with its mud-brick Great Mosque lie in the 400 km-long region.
An unusual feature of the river is the Inner Niger Delta, which forms where its gradient suddenly decreases. [20] The result is a region of braided streams, marshes, and large lakes; the seasonal floods make the Delta extremely productive for both fishing and agriculture.

The Niger Delta is made up of various networks of rivers and creeks mostly distributaries of the Niger River. [8] The soils of the delta vary by the shifting rivers and creeks, with sand and loam marking the remains of old levees, water-logged heavy clay in the backswamps behind the levees, and silty loam and clay on the higher ground.

The effects of the dams on the flooding of the Inland Niger Delta downstream of Mopti are expected to be modest, [18] as the discharge of the Bani is only one third of that of the Niger: for the period 1952-2002 the average flow at Douna was 424 m 3 (15,000 cu ft)/s compared with 1,280 m 3 (45,000 cu ft)/s for the Niger at Koulikoro.

In 2016 Shell paid US$80 million for the spill [1] Petroleum extraction in the Niger Delta has led to many environmental issues. [2] [3] The delta covers 20,000 km 2 (7,700 sq mi) within wetlands, formed primarily by sediment deposition.
The Niger River valley, which dominates the topography of Mali, drained by the Niger River and its tributaries. Along its course, the central southern region is the narrowest and is known as the Inner Delta or the Inundation Zone of the Niger, formed of 38,000 square kilometres (15,000 sq mi) of flood-plains, along a river length of 570 kilometres (350 mi); these form its wetlands of great ...
