pywr.domains.river.RiverGauge

class pywr.domains.river.RiverGauge(*args, **kwargs)

A river gauging station, with a minimum residual flow (MRF)

__init__(*args, **kwargs)

Initialise a new RiverGauge instance

Parameters

mrffloat

The minimum residual flow (MRF) at the gauge

mrf_costfloat

The cost of the route via the MRF

costfloat

The cost of the other (unconstrained) route

Methods
