WebJun 13, 2013 · Topographic roughness index (TRI). Roughness of the terrain can be identified by the surface slope (change of elevation). In rough terrain, difference in elevation of an area with its neighbourhood is high and thus rugged terrain is having high slope. Slope map was generated for all basins and classified into eight classes of 10° equal interval. WebChange in cereal production, yield and land use. Extent of extensive agriculture.
