Landscapes are mainly hillslopes with streams occupying less than 10% of drainage-basin areas. This book emphasizes tectonic geomorphology of hills, and treats the network of stream channels as the connecting link between upstream and downstream parts of a fluvial system.

William B. Bull is an applied geologist educated at Colorado and Stanford Universities. He worked 12 years for the U.S. Geological Survey as an engineering geologist and groundwater hydrologist and then changed career goals by moving to the University of Arizona where he taught geomorphology for 28 years. He continues to study how the hills and streams of mountain ranges respond to uplift and global climate changes of the past million years.
One of the appealing aspects of the book is that Bull uses a limited suite of landscapes with an array of climatic, lithologic and tectonic characteristics to highlight case studies. . . This work is well-suited for use as an upper level undergraduate textbook or as a resource for graduate students. (Geological Magazine, 2010)"Drawing on over 40 years of experience, this is the second geomorphology and neotectonics textbook that Bull has written in the last three years. Both books are well written and have a highly personal style." ("Geological Magazine, " 2010)
