Key physical parameters include sediment g … Key physical parameters include sediment grain size, sediment, density, water and sediment discharge, run time, the initial surface slope, the threshold sediment flux to propagate a new channel, and the allowed channel superelevation above the surrounding topography before avulsion. These parameters and the governing equations for the model are fully described in Limaye et al. (2023), Effect of standing water on formation of fan-shaped sedimentary deposits at Hypanis Valles, Mars, https://dx.doi.org/10.1029/2022GL102367s, https://dx.doi.org/10.1029/2022GL102367 +
Alluvial channel morphology is not explicitly modeled; rather, channel width, depth, slope, and discharges of water and sediment are represented as sub-grid characteristics. Each cell contains at most one channel. +

These files are convertible to netCDF file with coordinates for use with DeltaMetrics (https://github.com/DeltaRCM/DeltaMetrics).https://github.com/DeltaRCM/DeltaMetrics). +

Model for fluvial fan-delta evolution, ori … Model for fluvial fan-delta evolution, originally described by Sun et al. (2002) and later adapted by Limaye et al. (2023). The model routes water and sediment across a grid from a single inlet and via a self-formed channel network, where local divergence in sediment flux drives bed elevation change. The model represents hydrodynamics using rules for flow routing and stress partitioning. At large scales, other heuristics determine how channels branch and avulse, distributing water and sediment. The original model, designed for fluvial fan-deltas that debouch into standing water, is extended to allow deposition of an alluvial fan in the absence of standing water.</br></br>References: </br>Limaye, A.
