摘要

The understanding of hydrology in rivers is based not only on continuous water level measurements at gauging stations but also on discharge measurements and the derivation of rating curves. When validating this data, the Federal Waterways and Shipping Administration carries out water balance studies to validate and if applicable correct the consistency of the discharge time series at different gauges. In this paper, we describe the application of a new concept based on balance models in combination with a data assimilation approach and an AI-based error correction in application to reaches the Rhine and Main rivers.
