Introduction
Computational modeling is integral to the analysis, design, and assess-
ment of river hydraulics. Finite difference, nite volume, and nite ele-
ment methods for modeling river ows are common. These methods
have advantages and disadvantages. In recent decades, the discontinuous
Galerkin (DG) method, or so-called discontinuous nite element method,
has received great attention in computational uid dynamics (CFD). The
DG method combines the advantages of nite volume and nite element
methods. In this book, the DG method and its application to shallow
water ows are introduced. A brief historical overview of the DG method ...
