The first series of joint water discharge measurements across the whole Narva river were accomplished in Narva and Ivangorod cities on 31 July 2019. The series of more than 12 water discharge measurements is the first stage for the development of harmonised method of the Narva river runoff estimation. This valuable information will allow to calculate pollution load to the Gulf of Finland more precisely.
