In the first section of this book on
soil erosion, an introduction to the soil erosion problem is presented. In
the first part of the second section, rainfall erosivity is estimated on the
basis of pluviograph records and cumulative rainfall depths by means of
empirical equations and machine learning methods. In the second part of the
second section, a physically-based, hydrodynamic, finite element model is
described for the computation of surface runoff and channel flows.
This book is
organized into two sections. The first section covers three major aspects, viz.,
an understanding of patterns of land degradation and desertification for
developing mitigation strategies, land-atmosphere interaction from response of
land cover to climate change effects of Karst rocky desertification. The last
section dwells on the relationship between soil degradation and crop production
and an examination on how land degradation impacts the quality of soil in
communal rangelands.
