Abstract River is playing an important role in landform development, its shapes the structure of area. River process is a natural phenomenon supported by many agents such as precipitation. It has participated role in changing river behaviour, rainfall contributes in the volume of water and work as an agent in erosional process. Carrying scientific study to understand the characteristics of the area, river is one of the assets which describe the aspects and phenomenon related to Landforms. With the help of remote sensing & GIS, we can extract all the physical information of river, called morphometric parameters. The Singki river catchment accumulated an area of 79.8 Km 2 and has elevation 2353 metre; the rugged and irregular terrain surface shapes Dendritic drainage pattern.

Introduction Himalaya known as water tower of Asia because all the major rivers of India originate from Himalayan regions and all are perennial, the huge amount of Area is under Cryosphere. Arunachal Pradesh has five major rivers and its tributary including nine all are originates from Himalaya such as Siang is known as Yarlung-Tsangpo in Tibet originates from Angsi Glacier in Tibet and also known as Brahmaputra in Assam, Siang is the main tributary of River Brahmaputra, there are many small tributary joins Siang is Siyum, Yamne, Yameng etc. The River Subansiri is largest tributary of River Brahmaputra joins in the North Lakhimpur district of Assam, the river originates from China and has total length of 442 km. River Kameng is originated from Glacial Lake situated in Gori Chen Mountain district Tawang and also known as Jia-Bharali in Assam and a Tributary of Brahmaputra. From Eastern part of state a river flow towards South direction and later joined Brahmaputra called Dibang; it originates from Keya Pass on the Indo-China border. Before joining Brahmaputra River Lohit discharge water to River Dibang. Singki River flows in the foothills of Himalayan state, Arunachal Pradesh. The state is situated in the far-eastern region of India and also receives first dawn of Sunlight. The Singki River has 5 th order of streams and has characteristics of dendritic pattern (Figure 1). The river has a minimum discharge of 8857 MLD which is sufficient for Itanagar Town and it is controlled & managed by PHED department (Paron Omem et al., 2014). Singki is a perennial river flows with high velocity all year round and Open Access Research Article
