| Summary: | Hydrological modeling system was developed as a tool addressed supporting
flood risk management by the existing and projected reservoirs in the Amur
River basin. The system includes the physically-based semi-distributed model
of runoff generation ECOMAG coupled with a hydrodynamic MIKE-11 model to
simulate channel flow in the main river. The case study was carried out for
the middle part of the Amur River where large reservoirs are located on the
Zeya and Bureya Rivers. The models were calibrated and validated using
streamflow measuruments at the different gauges of the main river and its
tributaries. Numerical experiments were carried out to assess the effect of
the existing Zeya and Bureya reservoirs regulation on 850 km stretch
of the middle Amur River stage. It was shown that in the absence of the
reservoirs, the water levels downstream of the Zeya and Bureya Rivers would
be 0.5–1.5 m higher than the levels measured during the disastrous flood of
2013. Similar experiments were carried out to assess possible flood
protection effect of new projected reservoirs on the Zeya and Bureya Rivers. |
