Both erosion and deposition are continuous processes in the river in an attempt to reach a new equi- librium in channel geometry and morphology by the ever dynamic nature of flow. Erosion and deposition of the river have link to land use and land cover (LULC) as the land cover is under constant change in a dynamic landscape constantly shaped by continuous erosion and deposition. The objective of the present work is to evaluate the extent of erosion and deposition along the Brahmaputra river and change in the LULC of the Brahmaputra river in Assam, India. Remote sensing and geographic information system (GIS) techniques were utilised to extract information from Landsat images. Total area of erosion and deposition during 1973–2014 was 1557 and 204 km2, respectively.

  • Sediment Yield in the Mora Dhansiri River Catchment in Assam, India
    Trans.Inst.Indian Geographers ISSN 0970-9851 Sediment Yield in the Mora Dhansiri River Catchment in Assam, India Rana Sarmah, Guwahati, Assam Abstract This study attempts to estimate rate of sediment yield in a small size floodplain catchment with little physiographic and high climatic variations. Sediment yield rates are estimated adopting a field based conventional method for the period 2009-14. It has been estimated that rate of sediment yield in the study area is 618 t/km2/y. The average rate of sediment yield is estimated to be 417t/km2/y at gully-1, 451 t/km2/y at gully-2, 865 t/km2/y at gully-3, and 742 t/km2/y at gully-4 with an average of 618 t/km2/y for all gullies during 2009-14. Rate of sediment yield is increasing downstream in the order of 8t/km2/y/km primarily because of downstream fining of soil texture and increasing saturation level of the ground. It is found that rainfall of ground saturated period (July to October) has increased by 318mm (49%) during 2009-10 which yielded increase insediment yield of 127 t/km2/y (23%). This relation in 2010-11 became 266mm (27%) to 85 t/km2/y (12%) and in 2011-2014 36mm (3%) to 32 t/km2/y (5%). Thus, sediment yield rate is strongly determined by variation in rainfall of ground saturated period. It id also found that high rate of sediment yield in the stuy area is basically because of floodplain character of the basin with high anthropogenic interventions by tillaging the agricultural lands during the high runoff period.

E- mail: Abstract: Northeastern India, one of the Ichthyofaunal hot spot areas of our country, is marked by the presence of varied freshwater fishes,a few adapted to torrential waterflow. River Dhansiri is an important river of Dimapur District of Nagaland, India, which flows through Nagaland –Assam border harbouring rich aquatic flora and fauna. Very little studies have been carried out to document the fish biodiversity of the Dhansiri river till date. In the present study an attempt has been made common.to access the piscine diversity of this river. The survey results in finding of species of 34 fishes belonging to five (5) orders, thirteen (13) families and twenty four (24) genera. Cyprniformes is the dominant order while Osteoglossiformes is the least Introduction reported from Nagaland (Ao et al. 1988).

  • Evaluation of Sinuosity Index of Dhansiri (South) River Channel and Bank Erosion, Assam in GIS
    ISSN (Online) 2393-8021 ISSN (Print) 2394-1588 International Advanced Research Journal in Science, Engineering and Technology Vol. 2, Issue 5, May 2015 Evaluation of Sinuosity Index of Dhansiri (South) River Channel and Bank Erosion, Assam in GIS Plabita Barman 1, Dulal C.Goswami 2 Research Scholar, Department of Environmental Science, Gauhati University, Guwahati, Assam, India 1 Former Professor and Head, presently Guest Faculty, Department of Environmental Science, Gauhati University, Guwahati, Assam, India 2 Abstract: The Dhansiri River is a highly meandering river. Its Sinuosity Index has been evaluated using satellite imageries of 1999 and 2008 which varies from 1.22 to 4.91. The river acquires a meandering course as it flows through the alluvial plains of Assam and is responsible for frequent course change and shifting of banklines due to consistent bank erosion. The progressive gradual change of the meander bends has been observed by superimposing the river layers of 1999 and 2008 in GIS platform. The length of the river course in 2008 (307.74km) became shorter by 6.20 km than that in 1999(313.94km). In the present study it has been found that the total area lost as a result of erosion is 13.13834 sq km and the total area gained as a result of sediment deposition along its bank is 15.15894 sq km. Keywords: Dhansiri River, Sinuosity Index, GIS, Landuse, Landcover, Erosion. I. INTRODUCTION A geometrically straight river is rare. All natural rivers, been made for quantitative assessment on the total amount big or small, have an inherent tendency to deviate from a of the bank area subjected to erosion during a period of straight line and increase their sinuosity.

  • Action Plan for Dhansiri River-Priority V
    ACTION PLAN FOR DHANSIRI RIVER-PRIORITY V 1. Basic information about the Stretch The river Dhansiri originates from the south-west corner of Naga hill below the laishang peak. The river course can be divided in to two reaches. i) from source to the confluence of the river Diyung. ii) from confluence of the Diyung to the Brahmaputra. The Dhansiri basin is bounded by the river Brahmaputra in the north, Manipur in the south, Karbianglong district in the west, and the Jhanji basin in the east. The basin lies between latitude 26042’N & 25021’N and longitude 94037’E & 93010’E. The total length of the river from its source to outfall is approximately 352km and the total catchment area of the basin is 12,584 sq.km in plains. There are two major sub- tributaries of river Dhansiri) Kakodonga ii) Bhogdoi are also in Dhansiri catchment. For the first 40 km from its source, the river flows in a north westerly direction and thereafter it flows to north-east for about 76km up to Dimapur. Beyond Dimapur, the direction of flow is generally northerly up to Golaghat, where the river takes an abrupt turn towards North West and ultimately joins the Brahmaputra at Dhansirimukh. It is the main river of Golaghat district of Assam and Dimapur of Nagaland. The river attains a maximum breadth of 132 m near Golaghat and average depth is about 6.20 m. The hydrological station on the river at Numaligarh station indicates its danger level as 77.42 m and maximum, minimum and average water discharges as 209,185, 4.88 and 513 m³ sˉ¹respectively.
