Quality Models

The mogestpy.quality package groups the water-quality models shipped with MOGESTpy.

Zero-Dimensional Model

The zero-dimensional model represents a continued stirred (CSTR) reservoir and is useful for simple concentration balance studies. [BCG+23]

Example

from mogestpy.quality import zero_d

reactor = zero_d.ZeroDimensional(
    volume=[1000, 1000],
    Qin=[50, 50],
    Qout=[50, 50],
    Cin=[60, 60],
    As=[50, 50],
    k=[0.05, 0.05],
    v=[0.5, 0.5],
    timestep=50,
)

reactor.RunModel()
concentration = reactor.Output.ConcentrationOut

Build-Up/Washoff Model

The build-up/washoff model estimates pollutant accumulation on a surface and its transport during runoff events.

Example

from mogestpy.quality import buwo
