Developed tools and software:

1. Immersive online education tools for teaching slope safety awareness: A novel MOOC on slope engineering has been created and has been published on the HKMOOC platform. The MOOC uses innovative AR/VR technology for immersive learning and is freely accessible to the public. 
2. Development of a novel framework for precipitation forecasting STR-RainGAN, which is driven by dynamic data from the weather research and forecasting model. STR-RainGAN accurately predicts monsoon rainfall scenarios and provides a photo-realistic six-hour heavy nowcasting capability.
3. A prompt landslide risk assessment software PoLA has been developed for quantifying landslide and debris flow hazards induced by heavy rainfall. The code to this software can be found in this link.
