By Pierre Y. Julien
This textbook deals a radical research of rivers from upland parts to oceans. Julien scrutinizes choose tools underlining either conception and engineering purposes, emphasizing the mechanics of flood wave propagation and sediment shipping in rivers. Chapters offer specified remedies of riverbank stabilization and engineering equipment and canopy actual and mathematical versions. jointly, they elucidate measures to minimize flood impression and financial institution erosion, increase navigation, and raise water provide to towns and irrigation canals. greater than a hundred routines and approximately twenty case stories make this ebook a useful studying software for college kids. Hardback ISBN (2002): 0-521-56284-8

During the evening hours of July 31, a series of violent thunderstorms (Fig. 1) released large volumes of rain along a path several miles wide from Estes Park to the Wyoming border, as sketched in Fig. 2.
