xrspatial.erosion.erode

xrspatial.erosion.erode(agg, iterations=50000, seed=42, params=None)

Apply particle-based hydraulic erosion to a terrain DataArray.

Erosion is a global operation that cannot be chunked, so dask arrays are materialized before processing and re-wrapped afterwards.

Parameters:

• agg (xr.DataArray) – 2D terrain heightmap.

• iterations (int) – Number of water droplets to simulate.

• seed (int) – Random seed for droplet placement.

• params (dict, optional) – Override default erosion constants. Keys: inertia, capacity, deposition, erosion, evaporation, gravity, min_slope, radius, max_lifetime.

Returns:

Eroded terrain.

Return type:

xr.DataArray
