Best Practices for Distributed Rainfall-Runoff Models to Transform Hydrologic and Hydraulic Modeling for Resilient Transportation Planning and Design
Distributed rainfall-runoff models (DRRMs) are an important tool for assessing future precipitation impacts to the transportation system. With climate change raising the risk of more intense and frequent storms, water-related stressors, such as flooding, in-stream structure scour, and aggradation, could likely worsen for transportation corridors. DRRMs provide the capabilities needed to assess the impacts of future rainfall patterns and amounts on the transportation system. As detailed in NCHRP Synthesis 602: Resilient Design with Distributed Rainfall-Runoff Modeling, such modeling tools are cited in 54% of the hydrological design guidelines from all state transportation agencies, including state departments of transportation (DOTs) and pertinent state agencies, yet only 33% of the responding DOTs (16 out of 48) reported applying DRRMs. Without DRRM guidelines, transportation planning and modeling professionals will be limited in effectively leveraging innovative data sources, including the ATLAS 15 future precipitation dataset under development by the National Oceanic and Atmospheric Administration (NOAA). Accordingly, research is needed to begin transforming the state of practice in transportation hydraulic and hydrologic modeling and provide essential guidelines needed to fully leverage the ATLAS 15 future precipitation data and other future data sources. OBJECTIVE: The objective of this project is to develop resources that will facilitate state transportation agency adoption of DRRMs for planning and design.
