Title: Enhancing Flood Inundation Mapping through Standardized Databases and Model Collaboration
Abstract: In response to devastating flood impacts, effective Flood Inundation Mapping (FIM) models are essential. However, variability in model types and data formats of model output presents challenges in communicating results, and promotes redundancy and limited collaboration. Therefore, the development of a standardized database structure that allows for comparing all FIM models is critical to facilitate collaboration and prevent duplication of efforts. The National Water Center uses the HAND method for national FIM. The US Army Corps of Engineers has developed the HEC-RAS 1D and 2D models, which have been widely used for floodplain modeling. The Federal Highways Administration has adopted the use of SRH-2D for hydraulic design of roadway structures that can also be used to develop floodplains. While all of these models provide flood information, there is a lack of a uniform data structure that could be used in a web application.This research will test different methods, models, and datasets to enhance the National Water Center capability of FIM. A comprehensive FIM dataset will be compiled, storing model results and metadata for real-time and post-event analysis. The study will highlight the significance of visualization tools in assisting decision-makers in preparedness, mitigation, and response to forecasts.
