Opportunities from low-resolution modelling of river morphology in remote parts of the world

What is it about?

River morphodynamics are the result of a variety of processes, ranging from the typical small-scale of fluid mechanics to the large-scale of landscape evolution Problems inherent in the long-term modelling of large rivers derive from limited computational resources and the high level of process detail. Moreover, these modelling results depend on processes parameterization and calibrations based on detailed field data. In this paper, a simplified 1-D approach is presented that is suited for modelling very large rivers, such as the Zambezi River (Africa) and the Parana River (Argentina).

Why is it important?

The application of simplified models for describing river morphodynamics at watershed scale results very important especially in undeveloped or developing countries, where detailed field data are generally lacking.
