The State of the Roshydromet Hydrological Observation Network in the Mouth Areas of RFAZ

Le résumé fourni par la source

Abstract Taking into account the entire mouth network in its current boundaries, the authors pioneered in representing the historical development of hydrological observations at the stationary Roshydromet observation network in river mouth areas in the RF Arctic Zone. The main current problems of the state observations in the mouth areas of Arctic rivers are presented. The drawbacks in the organization of water level observations in the mouth network and water flow in the outlet sections of rivers emptying into Arctic seas are considered. Detail analysis is given to the agreement between data on water flow given in publications of RF Water Cadaster and the similar data stored in the Automated Information System “State Monitoring of Water Objects.” The hydrological data published in the Water Cadaster in many cases disagree with those in the latter system. This situation leads to errors in the estimates of hydrological characteristics.
