Special Issue Information

Dear Colleagues,

Urban flood and its risks have been changing in pattern, mechanism, and intensity due to the interaction of warming climate, rapid urbanization, and mitigation measures. Understanding these changes in urban flood risk relies on observation and modelling, which present challenges in urban areas where the mixture of natural and artificial landscapes is highly heterogenous over space. Recent developments on data acquisition and machine learning technique provide more physical-based, simplified, and data-driven opportunities on improving urban flood modelling, and further  enhance urban resilience to flood.

We welcome submissions that contribute, but are not limited to, the following topics:

  1. Urban flood mechanisms;
  2. Urban flood risk assessment;
  3. Data-driven flood modelling;
  4. Social sensing on urban flood;
  5. Urban flood in underground spaces;
  6. Urban flood resilience;
  7. Urban drainage design;
  8. Low impact development and sponge city.

This Special Issue particularly encourages papers that integrate machine learning with a hydrodynamic model.

In the low-lying, river-rich Pearl River Delta in South China, an extensive network of flood defense levees, spanning over 4400 km, plays a crucial role in urban flood management. These levees are designed to withstand floods and storm surges, yet their failure can lead to significant human and economic losses, highlighting the need for robust urban flood defense strategies. This necessitates the development of a sophisticated geographic information system for the levee network and rapid, accurate assessment methods for levee conditions to support water management and flood mitigation efforts. This study focuses on the levees along the Hengmen waterway in the Pearl River Delta, utilizing airborne Light Detection and Ranging (LiDAR) technology to gather 3D spatial data of the levees. Employing the Cloth Simulation Filter (CSF) algorithm, non-ground point cloud data were extracted. The study improved upon the region-growing algorithm, using a seed point set approach for the automatic extraction of levee point cloud data. The accuracy and completeness of levee extraction were evaluated using the quality index. This method achieved effective extraction of four levee types, showing significant improvements over traditional algorithms, with extraction quality ranging from 72% to 83%. Key research outcomes include the development of a novel method for detecting localized levee depressions based on the computation of the variance of angles between normal vectors in single-phase levee point cloud data. An adaptive optimal neighborhood approach was utilized to accurately determine the normal vectors, effectively representing the local morphology of the levee point clouds. Applied in three levee depression detection experiments, this method proved effective, demonstrating the capability of single-phase data in identifying regions of levee depression deformation. This advancement in levee monitoring technology marks a significant step forward in enhancing urban flood defense capabilities in regions such as the cities of the Pearl River Delta in China.
