It is highly important to evaluate flood risk at river basin scale to make specific proposals for structural and nonstructural options for flood management. The Miluo river, a typical flood prone area in Hunan province, China, was taken as an example to discuss flood risk assessment and countermeasures at river basin scale. Based on digital elevation model data, remote sensing data, local hydrologic data for this basin, analysis was performed on hazard of floods, vulnerability of exposures and flood risk by Hazard- Vulnerability Overlay Analysis Approach (HVOA), and main conclusions were drawn as follow: (1) it is feasible to perform flash flood risk analysis by HVOA approach, in which the computed area for hazard level assessment should be the entire river basin while the sites of interest was on only part of the basin; (2) it is important to manage residual risk and future risk, though the significant benefits of flood control will be achieved by the proposed subproject activities; and (3) risk management is still important for Pingjiang county to improve flood management capacity with the proposed project implementation, and some specific options were suggested on structural and nonstructural measures to achieve this objective at the Miluo River Basin scale.
