Struct RootSystem 

pub struct RootSystem {
    pub root_type: RootType,
    pub max_depth_m: f32,
    pub spread_radius_m: f32,
    pub water_uptake_rate: f32,
}

Root system properties.

Fields

root_type: RootType

max_depth_m: f32

spread_radius_m: f32

water_uptake_rate: f32

Implementations

impl RootSystem

pub fn oak() -> Self

pub fn grass() -> Self

pub fn mangrove() -> Self

Mangrove: adventitious prop roots, coastal.

pub fn root_zone_fraction(&self, soil_depth_m: f32) -> f32

Root zone fraction — how much of the soil column this root system can access (0.0–1.0).

fraction = min(1.0, max_depth_m / soil_depth_m)

Shallow roots in deep soil access less water; deep roots in shallow soil access all.

• soil_depth_m — soil column depth (meters)

pub fn water_uptake_mm( &self, soil: &SoilWater, transpiration_demand_mm: f32, ) -> f32

Water uptake from soil (mm/day).

Actual uptake is the minimum of:

1. Transpiration demand (what the canopy needs)
2. Root capacity (water_uptake_rate scaled to soil area, liters/day → mm/day)
3. Available water in the root zone

Root zone depth limits access: shallow roots in deep soil only see a fraction of available water.

• soil — current soil water state
• transpiration_demand_mm — canopy transpiration demand (mm/day)

pub fn stabilization_factor(&self) -> f32

Soil stabilization factor (0–1, dimensionless). Fibrous roots stabilize better per area.
