Numerical Modeling in Fluvial Geomorphology

Numerical models of fluvial geomorphology have become an important tool for investigating and understanding how our landscapes are shaped by water. During the last two decades many types of model have been developed simulating processes ranging from bank erosion during a single flood to entire catchments over thousands of years. These models all have their bespoke purpose as well as advantages and limitations. In this chapter, we present a review of the different types of model that have been developed for modeling fluvial geomorphology. Additionally, we discuss the difficulties and issues faced modeling fluvial processes such as calibration, validation, nonlinearity, and uncertainty. Finally, we discuss what possibilities and challenges lay ahead for modeling of fluvial geomorphology.
