Trajectory modifiers¶
Trajectory modifiers classes change the path of particles, examples from standard trajectory_modifiers classes below.
Particle behaviour¶
Particles with a random fraction temporarily frozen on a polygon shaped reef.
class:
trajectory_modifiers.settlement_in_polygon.SettleInPolygon
json parameters
yaml parameters
Resuspension¶
Particles with fall velocity and resuspension based on critical friction velocity.
class
trajectory_modifiers.resuspension.BasicResuspension

Vertical slice showing one example of a falling particle and resuspension, with particle on bottom during low flows around low and high tides. Blue line is particle status, 10= moving, 6 = on the bottom.

Splitting particles¶
Particles with splitting in two every 6 hours and a 5% chance of dying every 6 hours.
class:
trajectory_modifiers.split_particles.SplitParticles
class:
trajectory_modifiers.cull_particles.CullParticles
