Abstract

A river or stream is dynamic through time. The most significant morphological property of a river is the meandering process, which is dominated and governed by hydraulic, hydrologic and topographic characteristics of the river and its drainage area [1]. In a meandering river, the length of the river keeps on increasing by eroding the outer bank of a bend [2]. The present study has been conducted to investigate the meandering parameters of Manu River using Remote sensing technology and Geographic information system. The name Manu River used here to represent the river reach from Tripura border to the confluence with Kushiyara River in Manumukh, Sherpur. Ten critical bend have been chosen in Manu River which are changing over time. The minimum width as found was 52.6 m at near Brahman-bazar (chainage 22.58 km) in 1997; the maximum width was 80.6 m near Rajnagar (chainage 34 km) in 2006. Meandering ratio varies from 0.32 to 1.67 and wavelength 558.31 m to 1803.54 m. The Sinuosity of the river ranges from 1.36 to 2.48.
