This chapter discusses the influence of causal factors for landslide hazard mapping and stability of the prediction results. Among many quantitative models, we consider a model based on the theory of fuzzy sets with the algebraic sum operator. In the model, layers of geoscience maps represent the spatial information used for the prediction of areas in which the geomorphologic setting is similar to the ones in which a particular type of mass movement has taken place.
Land forms and drainage patterns are being studied by more and more elaborate methods all the time. The increasingly accurate methods of measuring land form and geomorphological processes are providing a vast amount of quantitative data. This has to be analysed by numerical methods so that an orderly behaviour may be discerned from amongst the mass of accumulated data. This book sets out to provide an introduction to those numerical methods which we have found to be most useful in the analysis of geomorphological data.
In the preparation of this book I have drawn upon the help of many people and institutions. Many of these have no direct connection with the writing of the book, but without their assistance, which made the necessary field experience possible, this study could not have been written.
Most of the land surface of the earth is formed by valley slopes. At a given point on the ground surface it is normally possible to follow the line of maximum slope downwards until a drainage channel is reached; moreover a causal relation between the slope and the channel is apparent. This feature has been little remarked upon, possibly because it is so widespread as to seem part of the natural order. It is nevertheless a fundamental and remarkable feature of the earth’s surface form. <...>

Remote sensing has been immensely useful in tectonics, structural geology, and geomorphic studies (e.g. Misra et al. 2014; Dasgupta and Mukherjee 2017, 2019; Shaikh et al. 2020; Dasgupta et al. 2022). This edited book consists of 24 chapters authored and co-authored by 53 persons from 21 academic organizations and industries from 7 countries. Misra (2022a; Chapter 1) presents the definition, fundamental processes, and scopes of remote sensing in structural geologic and geomorphologic studies. Misra (2022b; Chapter 2) pens the next introductory chapter, which classifies remote sensing based on data type, source, platform, and imaging media. Gupta and Biswas (2022, Chapter 3) present a morpho-tectonic analysis of a mid-channel bar using remote sensing images from the Jaldhaka river (India). Deota et al. (2022, Chapter 4) present geomorphic indicators of glacier retreat from Jorya-Garang glacier, Baspa Valley (India). They identify different stages of moraines. Jordan (2022, Chapter 5) presents several interesting aerial views of the 2018 Kilauea eruption (U.S.A). Geomorphic features such as lava fissures are documented from images. Awais (2022, Chapter 6) documents different kinds of depositional systems observable in images in Google Earth, viz. different rivers, deltas, lakes, alluvial fans, dunes, and estuaries. Patel et al. (2022, Chapter 7) discuss in detail badland geomorphology from images and several field photos. Their study area was Garbeta (India). Dongare et al. (2022, Chapter 8) discuss the geomorphology of the Indian west coast.
Hillslopes occupy most of the land surface of the Earth. In areas of erosional topography the entire landscape, except the valley floors, consists of hillslopes. Consequently, hillslopes are a major focus of research in geomorphology. The study of hillslopes is essential not only in order to understand better the natural landscape but also for numerous practical reasons, such as controlling soil erosion and sedimentation on agricultural lands and mitigating the hazard posed by landslides. Geomorphologists have studied hillslopes since the latter part of the 19th century, but until the late 1950s their research focused almost exclusively on morphology. During the past 30 years, however, there has been a growing interest in hillslope processes, and today research on processes dominates this branch of geomorphology <...>
