CASCADE (CAtchment Sediment Connectivity And Delivery) is a modelling framework for sediment transport and connectivity in large rivers developed at Politecnico di Milano by the Environmental Intelligence team, in collaboration with UC Berkeley.
The model provides estimations of sediment fluxes and reach sediment budgets in the whole network and allows for the tracking of multiple sediment fluxes as they move throughout the system.
CASCADE takes advantage of the availability of geomorphic and hydrologic data in large-basins or at global scales to describe sediment connectivity in data scarce environments.
Low computational time, even for large networks, allows for extensive sensitivity analysis and applications in intregrated river basin planning
CASCADE toolbox is freely available, and requires MATLAB 2017b or higher, with the Text Analytics Toolbox and the Bioinformatics Toolbox. For the extraction of the river network graph from a Digital Elevation Model, CASCADE requires the functions from TopoToolbox 2.2, a Matlab based open souce software for topographic analysis (Schwanghart and Scherler, 2014).

In these pages we provide short summaries on the main topics covered by CASCADE. The informations supplied are designed to just give a general idea of the themes involved, and are by no means exaustive. We suggest to use the provided references and the CASCADE manual for further informations.
What is the CASCADE Toolbox?
CASCADE toolbox is an open source toolbox containing the operations necessary to run CASCADE on a river network extracted form a Digital Elevation Model and to interactively explore the model outputs.

What is river sediment connectivity?
Sediment connectivity is a fundamental property of river network. It describes the multiple sediment delivery processes occurring in the network, from sediment detachment from banks and hillslopes to sediment deposition in sinks and deltas. Preserving natural sediment connectivity is necessary for the well-being of the river systems and all the ecosystem and human populations depending on its resources and services.
