Basin and Landscape Dynamics (Badlands) is a long-term surface evolution model built to simulate landscape development, sediment transport and sedimentary basins formation from upstream regions down to marine environments.

Badlands is an open-source Python-based code and can be used to simulate:

• hillslope processes (linear & non-linear diffusion),
• fluvial incision (Stream Power Law, Transport Capacity Law)
• sediment transport and deposition,
• wave-induced longshore drift transport,
• reef growth and carbonate platform formation,
• submarine gravity currents (turbidity currents),
• spatially and temporally varying tectonic (horizontal + vertical displacements) and
• effects of climate changes (rainfall) and/or sea-level fluctuations.
