Peru. Since, Amazon River receives a huge discharge of nearly 2 lakh m3/s, it washes off the load supplied to it from the catchment and as a result sediments is not deposited even at the mouth. A dense network of distributaries characteristic of river mouth areas, is to a large extent absent in the mouth region of the Amazon.

Meanwhile, the west flowing rivers located in the area between the Western Ghats and the Arabian Coastline are short but swift. Such a short and swift river system exists in the states of Kerala, Karnataka, Maharashtra and Southern Gujarat. Further northwards, are the river systems such as Tapi, Narmada, Mahi and Sabarmati flowing into the Gulf of Khambhat. Tapi and Narmada flow slowly through rift valleys, while Mahi River flows from North East to South West direction whereas River Sabarmati collects its headwaters from the southern slopes of Aravali ranges and flows in a somewhat North-South direction.
