Newly compiled continental river discharges of water and biogeochemical tracers 1977 - 2023
Remarks:
 - IJssele (Kornwerderzand)
     waterdischarge locally
     concentration and load values derived from concentrations at Vrouwenzand and local water discharge 
 - IJsselw (Den Oever)
     waterdischarge locally
     concentration and load values derived from concentrations at Vrouwenzand and local water discharge
 - negative or zero daily discharge leads to vanishing daily input

Scheldt
TN1 2021 from KjN
TN2 2022/23 from TN
All new 2020 nutrient data equal to old time series 

NZK
DIS until 2023. 2019 was equal to old time series. No value 2022
KjN until 2021. new 2020 data was not equal to old time series: take new values for 2020/21 
TN1 2020/21 from KjN. 2020 and 2021 from new time series
TN2 22/23 from raw data
N23, NH4, NO2, NO3, PO4, Si, TP: new 2020 data unequal to old time series: Take new values since 2020
New nut 22/23 data fit to older 

VRS
All parameters overlap for 2022

Elbe, Weser, Ems: New dis deviates from old TS (see graphs): Use new data since 2020. Old stay until 2019.
