Surface Flow

Surface flow inflows inject water along a line at a specified volumetric flow rate.

Properties

Property Type Description
type string Must be "Surface"
data string Flow rate in m^3/s

Usage

Surface inflows are drawn as LineString features. The flow rate is distributed along the line.

"data": "0.5"

This injects 0.5 m^3/s along the line for the entire simulation.

How it works

Internally, surface inflow lines are applied as ANUGA Inlet_operator instances. The line must be within the domain boundary — lines outside the boundary are silently ignored.

Tip

Surface inflows are useful for modelling pipe outfalls, creek inflows, or other point/line sources of water entering the domain.
