Research on determining the risk of downstream flooding of Nui Coc reservoir, Thai Nguyen province

Abstract

The paper has studied the application of risk analysis methods to assess flood risks of the downstream
of reservoirs, typically applied to Nui Coc reservoir through systematic analysis from headworks to
downstream to determine safety index of the headworks and flood damage in downstream of reservoirs
and proposing structural measures and non-structural measures to minimize the risk of downstream
flooding. This method is being widely developed in the World. The case study for Nui Coc shows the
applicability in Vietnam in recent years, when climate change causes extreme rain and flood to be
complicated and abnormal, affecting the safety of the reservoir.
Keywords: Downstream flood risks, downstream risk analysis, downstream safety, downstream
damage, Nui Coc reservoir.
