Short Summary

This study investigates the impact of land use change, driven by rapid urbanization, on urban flooding processes in Wuhan, China. It found that urban expansion significantly increases rainwater accumulation and alters flood dynamics, such as peak flow velocity and timing, thereby intensifying flood risk and reducing emergency response time.

Objective

• To reveal the impact of land use change on urban flooding processes, specifically focusing on the main urban area of Wuhan (MUAW).

Study Configuration

• Spatial Scale: Main urban area of Wuhan (MUAW), China.
• Temporal Scale: Land use data from 2006 and 2020 (a 14-year period); simulated rainfall events with return periods of 5, 50, and 100 years.

Methodology and Data

• Models used: NewFlood two-dimensional hydrodynamic model.
• Data sources: Land use data (2006, 2020); designed rainfall events; validation against flood-prone locations (implying observational data for validation).

Main Results

• Between 2006 and 2020, land use transfer in MUAW was primarily influenced by urban sprawl and a reduction in cropland.
• Urban expansion led to an increase in the area and depth of rainwater accumulation during rainstorms, aligning with the direction of urban sprawl and increasing urban flooding risk.
• Land use transfer had a limited impact on the maximum water depth and flow direction in MUAW but increased peak flow velocity or shifted the peak time earlier, reducing available emergency response time.

Contributions

• Quantifies the waterlogging effect of land use change from dynamic dimensions, specifically "flow velocity—peak occurrence time."
• Provides process evidence for assessing urban early warning advance, allocating drainage capacity, and controlling land use.
• Offers a reference for prioritizing the layout of nature-based solutions and green infrastructure in low-lying catchment areas and key catchment channels to reduce flood risks.
