Floods play a key role in landform evolution of an
\r\narea. This process is likely to alter the topography of the earth’s
\r\nsurface. The present study area, Kota Bharu is very prone to floods
\r\nextends from upstream of Kelantan River near Kemubu to the
\r\ndownstream area near Kuala Besar. These flood events which occur
\r\nevery year in the study area exhibit a strong bearing on river
\r\nmorphological set-up. In the present study, three satellite imageries of
\r\ndifferent time periods have been used to manifest the post-flood
\r\nlandform changes. The pre-processing of the images such as subset,
\r\ngeometric corrections and atmospheric corrections were carried-out
\r\nusing ENVI 4.5 followed by the analysis processes. Twenty sets of
\r\ncross sections were plotted using software Erdas 9.2, ERDAS and
\r\nArcGis 10 for the all three images. The results show a significant
\r\nchange in the length of the cross section which suggest that the
\r\ngeomorphological processes play a key role in carving and shaping
\r\nthe river banks during the floods. <\/p>\r\n","references":"[1] R. Bartley, J. R. Keen, A. A. Hawdon, M .G. Disher, A. E. Henderson, P. B.
