finding concave surface from DEM

[YoshiroNagao]

Dear All,

Is it possible to delineate the extent of concave surface from a DEM?

The output can be either a raster or shape.

I am predicting the spread of a pollutant. The pollutant will be accumulated in concave places, such as pit, hollow, depression, basin.

Thank you.

See the Curvature tool.
