Newly compiled continental river discharges of water and biogeochemical tracers 1977 - 2014
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 
 
 - Elbe augmented till end of 2019. In 2017 Q old had some small errors 
 
 - new data 2017 - 2019 (2020 for NL Conc)
   PO4 and NH4 for VrouwZand has been corrected by the data suppliers mainly for January 2017
   This leads to a change in the annual loads at VrouwZand and IJSSELW and IJSSELE for NH4 and PO4, respectively.

Scheldt
CL from salinity for 2019-2022. 21 and 22 used for prolongation of the timeseries with Monikas formula. 19/20 overlap with deviations
TN1 2021 from KjN
TN2 2022 from TN
All new 2020 nutrient data equal to old time series 

NZK
DIS until 2021. 2019 was equal to old time series
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

VRS
All parameters overlap for 2020 OK. Only PO4 unequal: take new values for 19/20

HARI
ALL parameters overlap OK

IJSE (KornwederSand)
DIS overlap OK

IJSW (Den Oever)
DIS overlap OK

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