Abstract

Addressing the current issues of an imperfect social benefit assessment system for flood control and disaster reduction and a lack of quantitative methods, this study constructs a set of evaluation indicator systems and methods for the social benefits of flood control and disaster reduction through water project operations. This system starts from four dimensions: regional population health impact, regional development impact, production and living impact, and social flood control pressure. It establishes six secondary indicators: population casualty rate, regional economic development enhancement benefit, agricultural structure adjustment benefit, social critical infrastructure impact benefit, flood control embankment operation and management cost, and flood disaster relief cost. Taking the 2020 flood in Luzhou City as an example for validation, the results show that flood control operations can significantly reduce population casualty risk, promote regional economic development (benefit increase of 0.76%), reduce agricultural losses (increase output value by 238 million CNY), reduce infrastructure failure nodes by 5.46%, and save embankment management costs by 314 million CNY and relief costs by 524 million CNY. The case study demonstrates that the proposed indicator system can systematically quantify flood control social benefits, providing scientific support for water project operation decision-making.
