- The Tizu River forms an important drainage system in the eastern part of Nagaland.
- It originates from the central part of Nagaland state and runs through a northeast direction, flows through Kiphire and Phek districts and confluences in the Chindwin River of Myanmar.
- The Chindwin River further enters into Irrawaddy River, the largest river of Myanmar.
- The River Irrawaddy further drains into the Andaman Seavia the Irrawaddy Delta after travelling through river ports like Mandalay.
- The main tributaries of the River Tizu are river Zungki, Lanye, and Likimro.
- The Zungki River, which is the biggest tributary of Tizu, starts from the north-eastern part of Changdong forest in the south of Teku, and flows in a southern direction towards Noklak, Shamator, and Kiphire, and finally joins Tizu below Kiphire.
About National Waterways 101:

Deltas are wetlands that form as rivers empty their water and sediment into another body of water, such as an ocean, lake, or another river. Although very uncommon, deltas can also empty into land.
