One-line model description	Geometric model to study the response of fluvial-deltas to base-level changes.
Extended model description	We present a geometric model able to track the geomorphic boundaries that delimit the fluvial plain of fluvial-deltas: the shoreline and the alluvial-bedrock transition. By assuming a fluvial profile with a quadratic form, which satisfies the overall mass balance and the boundary conditions dictated by diffusive transport, we are able to provide a solution that accounts for general base-level changes.

Keywords:	delta evolution, shoreline dynamics, alluvial-basement transition, base-level changes,

Describe input parameters	[[Describe input parameters model::1. Length scale [L]. 2. Fluvial diffusivity [L^2/T]. 3. Basement slope [-]. 4. Alluvial-basement slope ratio [-]. Ratio between fluvial and basement slopes at the alluvial-basement transition. Its value is physically constrained to be in the range (0,1). 5. Base-level curve.]]

Describe processes represented by the model
Describe key physical parameters and equations	The key physical parameters are: (1) length scale, (2) fluvial diffusivity, (3) basement slope, (4) sediment input from the river inputs, and (5) base-level curve. The key equations are a sediment mass balance and four boundary conditions. Two boundary conditions are derived geometrically, and the other two are obtained by assuming that the sediment flux is a function of the local slope (i.e., diffusion).
Describe length scale and resolution constraints

Describe any numerical limitations and issues

Describe available calibration data sets	No calibration data sets. We validate the model against available analytical solutions and use it to analyze the system behavior under a general base-level fall and base-level rise. See Lorenzo-Trueba et al. 2012.
