  "abstract": "Riverine topographic diversity is widely associated with spatial and temporal variation in hydraulic habitat under flood disturbance. Yet, most existing habitat assessments remain limited to static or quasi-steady flow conditions, restricting the development of indicators that capture habitat responses across complete flood cycles. This study examined the flood-prone Leshan reach of the Min River, using the round-mouthed copper fish ( Coreius guichenoti ) as the indicator species. A flood-cycle hydraulic-habitat assessment framework was developed by integrating hydrodynamic–habitat coupling with the Regional Integrated Suitability Index ( RII ), Hydraulic-Habitat Stability Index ( ESI ), Short-Term Hydraulic-Habitat Recovery Index ( EI ST ), and geomorphic-complexity indicators. Results show that river morphology is strongly associated with hydraulic-habitat dynamics: mid-channel bar reaches exhibit higher ESI under flood disturbance and a greater capacity to sustain suitable hydraulic habitat over time, whereas single-channel reaches exhibit lower hydraulic-habitat stability during intense flood disturbance but higher EI ST by the common event-end time. These contrasting responses indicate temporal functional complementarity at the hydraulic-habitat level in maintaining suitable hydraulic conditions and achieving short-term recovery. The Mid-Channel Bar Complexity Index ( MBCI ) is positively associated with ESI and captures additional geomorphic information beyond individual metrics under intermediate flood conditions, reflecting the combined contributions of mid-channel bar abundance, local topographic heterogeneity, and effective flow space. Overall, contrasting river morphologies have the potential to provide functionally complementary hydraulic-habitat responses under flood pulses. The framework provides a quantitative basis for identifying reaches with greater potential to maintain or recover spawning-suitable hydraulic conditions in flood-prone mountainous rivers.",
