Abstract
Greenhouse gas emissions are contributing to more extreme rainfall events, causing urban flooding. Traditional flood mitigation methods that rely on hydraulic structures are proving ineffective and emit high levels of carbon. In line with the UN’s 2050 net-zero carbon emissions, prioritizing carbon sinks is critical. This study examines the relationship between soil moisture content and soil carbon sequestration and proposes an innovative strategy. By increasing soil moisture and adjusting urban land use, the study aims to simultaneously mitigate flooding and increase soil carbon sequestration. Wetlands with high soil moisture were selected for carbon assessment. The sampling points and depths were selected through an analysis of the geological soil layers. The soil organic matter was calculated using the Walkley-Black wet oxidation method and the measurement of heat loss of organic matter. Results show a positive correlation between soil carbon sequestration and soil moisture. Changing urban land use to improve soil quality and moisture reduces flood depths, providing an alternative approach to disaster prevention while promoting carbon sequestration.
