This option assumes a constant flow of wastewater at the sampling site. Can be used as an approximation if no regular flow measurements are available.
Usage
flows_assume(flow_constant, modeldata = modeldata_init())Arguments
- flow_constant
Daily wastewater flow volume, assumed to be the same for all days.
- modeldata
A
modeldataobject to which the above model specifications should be added. Default is an empty model given bymodeldata_init(). Can also be an already partly specified model returned by otherEpiSewermodeling functions.
Value
A modeldata object containing data and specifications of the model
to be fitted. Can be passed on to other EpiSewer modeling functions to
add further data and model specifications.
The modeldata object also includes information about parameter
initialization (init), meta data (.metainfo), and checks to be
performed before model fitting (.checks).
Details
The flow volume unit should be the same as for the concentration measurements, e.g. if concentrations are measured in gc/mL, then the flow should be in mL as well.
Note that when the flow is unknown and therefore some arbitrary
value (e.g. flow_constant=1) is assumed, this must also be accounted for
in the assumed load_per_case. For this purpose, the function
suggest_load_per_case() offers a flow_constant argument.
