Rock-Mantled Slopes

摘要: This chapter will consider hillslopes with gradients less than 40° that are neither active, undissected piedmonts (i.e. pediments and alluvial fans, which dealt in Chapters 13 14) nor developed highly erodible, fine-grained sedimentary rocks badlands slopes, treated Chapter 9). Such desert (arid semi-arid) climates usually mantled a thin layer of coarse debris has either weathered out the underlying substrate or fallen from superincumbent cliff. The former herein referred to as slopes latter talus slopes. In this we shall first processes acting on these rock-mantled then forms they produce. These not only important terms understanding hillslope form but because give rise variety hydrologic geomorphic phenomena such flash flooding, extreme soil erosion, hazardous flows.
