# dissipation3D Section

This section configures **3D dissipation parameters**, including **vertical diffusion** and **turbulence closure models**.

---


 | **Parameter** | **Description** |
 |---------------|----------------|
 | *(Inherits all parameters from `dissipation2D` for horizontal dissipation)* |
 | `turbulence_closure` | Turbulence closure model (`CONSTANT`, `YAMADA`, `GALPERIN`, `GASPAR`, `TKE`, `KOMEGA`, `HOMOGENEOUS`). |
 | `lateral_diffusion_coefficient` | Lateral diffusion coefficient (default: `0.0 m²/s`). |
 | `vertical_diffusion_coefficient` | Vertical diffusion coefficient (default: `1.e-04 m²/s`). |
 | `tracer_vertical_diffusion_coefficient` | Vertical diffusion coefficient for tracers (default: `1.e-04 m²/s`). |
