Lots of attempt have been made to analyze sediment transport processes within submarine canyons using numerical modeling technique. What other importance could the said modeling serve?
Numerical modelling has many advantages. It allows for examination of different processes that may influence circulation within canyons where it is difficult to make extensive measurements. It also allows for selecting regions to where measurements can be undertaken.
The difficulty with sediment transport processes is that in some regions the canyons are a conduit to transport sediment offshore (e.g. those in the Mediterranean) in contrast others are upwelling favorable and support a large ecosystems (oasis) in the ocean (e.g. Australia). Often they may support both depending on the oceanography.
Here are some papers that may interest you some modelling some observations:

Additionally, numerical modeling allows for assuming many scenarios
and study the response of your system to these different changes in important parameters that affected the system, and by using the numerical models, we can examine the characteristics in places located far away that we cant make measurements there.
