Inundation mapping is a research area focused on mapping and forecasting areas that are at risk of flooding or inundation. This includes mapping the extent of floodplains, coastal areas prone to storm surges, and areas that are vulnerable to flash floods. Inundation mapping relies on high-resolution topographic data, hydrological models, and remote sensing techniques to accurately predict areas at risk of flooding and to inform emergency response and land-use planning. It is an important tool in mitigating the impacts of flooding on communities and ecosystems.
