8 Hillslopes and landform evolution 215 Mike Kirkby
8.1 Introduction 215
#Over 90% of landscapes that are currently not glaciated consist of hillslopes [leeng bukit], and the remainder consist of river channels and their floodplains
8.2 Slope profiles 216
#The appearance of hillslopes around the world varies considerably
(Allen, 1997). Some of these differences are related to the vegetation and soils on the hillslopes, but there are also important differences in the form of hillslope profiles. Most profiles are convex near the divide (top of the slope) and concave near their base ( Figure 8.1 ). The most significant differences between them are in their total length, gradient and convexity.
