19.1 Introduction

Rivers appear as physical substances, carrying water and sediments from the headwater to the sink. Since the dawn of civilization, humans have directly or indirectly depended on river resources for ecological growth and survival (Schumm, 2005). A river can be bedrock or alluvial and is fed by glaciers, snow, precipitation, groundwater, or lakes. The bedrock rivers are critical geomorphic markers as they play an essential role in shaping the landforms by responding rapidly and consistently to any change in tectonics and climate (Seeber and Gornitz, 1983; Ouchi, 1985; Holbrook and Schumm, 2000; Amos and Burbank, 2007; Jain and Sinha, 2009).
