Hillslopes are a significant feature of the natural landscape. They play a crucial role in organizing the availability of water on land. Such organization of water gives rise to distinct characteristics in soil and vegetation. Such differences can be observed between soil and vegetation of hilltops, valleys and between sunny and shady slopes. The topographic gradients present on the hillslopes drive water, sediments and biogeochemical fluxes down the hillslopes. An important area of study in this field is the interplay of sediments, subsurface flow, soil erosion and overland flow. Effective stress is the primary factor which affects the stabilizing strength of hillslope materials. This book is a valuable compilation of topics, ranging from the basic to the most complex advancements in hillslope hydrology. From theories to research to practical applications, case studies related to all contemporary topics of relevance to this field have been included herein. This book, with its detailed analyses and data, will prove immensely beneficial to professionals and students involved in this area at various levels.
