Crate hydro_analysis

Hydro-analysis

hydro-analysis provides functions for Hydrology DEM manipulation that are based on whitebox. Whitebox is a command line tool, this crate provides some (only a couple functions at present) of that functionality via functions so can be called from your code.

Example

use ndarray::Array2;
use hydro_analysis::fill_depressions;

let mut dem = Array2::from_shape_vec(
    (3, 3),
    vec![
        10.0, 12.0, 10.0,
        12.0, 9.0,  12.0,
        10.0, 12.0, 10.0,
    ],
).expect("Failed to create DEM");

fill_depressions(&mut dem, -3.0, 8.0, 8.0, true);
let (d8, d8_nd) = d8_pointer(&dem, -1.0, 8.0, 8.0);

Functions

d8_pointer

Calculates the D8 flow direction from a digital elevation model (DEM).

fill_depressions

Fills depressions (sinks) in a digital elevation model (DEM).
