This study presents an integrated framework for identifying, designing, and evaluating palaeochannels as a nature-based solution for flood mitigation at the floodplain scale. The framework combines field observations, GIS analysis, high-resolution two-dimensional hydrodynamic modelling, and flood hazard and damage assessment. Palaeochannels are first identified using aerial imagery and digital elevation data, then incorporated...

Designing Nature-based Solutions for flood mitigation in catchments can benefit from integrated decision-support frameworks (DSFs) that analyse trade-offs effectively. This study presents a framework for evaluating catchment-scale solutions, particularly reforestation, for flood risk reduction. It combines a semi-distributed hydrological model, flood frequency analysis (FFA) using the Log-Pearson Type III distribution, and reg...
