This option accounts for daily wastewater flow volumes measured at the sampling site. The flow can change due to rainfall or industrial discharge, and directly influences pathogen concentrations in the wastewater.
Usage
flows_observe(
flows = NULL,
date_col = "date",
flow_col = "flow",
modeldata = modeldata_init()
)Arguments
- flows
A
data.framewith each row representing one day. Must have at least a column with dates and a column with flow measurements.- date_col
Name of the column containing the dates.
- flow_col
Name of the column containing the flows.
- 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.
