Smart Coastal City: Disaster Risk Management

Disaster Risk Management in coastal cities includes all action, programs and measure that city government do before, during and after the disaster that minimise the loss or impact due to the coastal disaster happening and to speed up the recovery of the community that are impacted. Technology can help the process of disaster planning and management through various remote sensing and radars. For instance, systems that provide warnings for flash floods necessitate a comprehensive network of rain gauges to monitor intense local rainstorms. The collected data then needs to be interpreted by employing empirical models that establish real-time correlations between river levels and flow intensity. This is crucial for early flood forecasting and subsequent timely alerts. 

However, Tonmoy et al. (2020) found that this next level of technological use that analyse real time data for better future planning and management of coastal disaster has yet been widely use by cities. This is a implementation gap of the technology in many smart cities. The study also highlights the potential development of other types of sensors that are still understudied such as temperature sensors and pressure sensors that are relevant in the coastal hazard detection.
