This function converts flow time series from cumecs (m3/s) to mm/d by dividing the flow by the catchment area and converting it to mm/day.
convert_flow(flow_cumecs, catchment_area)
This is the flow time series in cumecs (m3/s)
This is the catchment are in Km2.
Flow time series in mm/d
if (FALSE) {
convert_flow(30, 2)
