Abstract
The three-year research programme aimed to pursue the development of novel modelling
tools for the description and prediction of geomorphic mountain flows. The approach is based
on a multi-component, shallow layer description of horizontal two-dimensional flow. The
overall programme sought to: 1) establish governing equations accounting for the coupled
motion of water, liquefied soil, and transported sediment; 2) develop and implement suitable
computational techniques; 3) test the equations and computations against theoretical,
experimental and field information. The key findings of the research are documented in the
present report. They are structured in three broad categories: 1) modeling of sharply stratified
shallow flows; 2) treatment of interfacial transfer terms; 3) development of a reduced theory
and applications to prograding deltas and geomorphic floods at the field scale. The aims
attained and further work needed are described in a final section.
