State departments of transportation (DOTs) are being asked to account for climate change in hydrologic and hydraulic (H&H) design practices. Current H&H design procedures stipulate the use of historical data assumed to represent a stationary process. Climate change introduces non-stationary risks such as rise in sea level, rise in temperature, and changes in the timing and distribution of precipitation, snowpack, and snowmelt. Failure to account for such non-stationary risks may compromise the operational characteristics of existing and future transportation infrastructure.
NCHRP Project 15-61, "Applying Climate Change Information to Hydrologic and Hydraulic Design of Transportation Infrastructure," delivered a document titled "Applying Climate Change Information to Hydrologic and Coastal Design of Transportation Infrastructure: Design Practices."
Additionally, NCHRP Project 20-44(23) conducted pilot tests with state DOTs to determine the effectiveness and ease of implementation of the guidelines developed under NCHRP Project 15-61.
Research is needed to incorporate additional climate science information into inland and coastal H&H design of transportation infrastructure.
The objective of this research is to develop a guide for state DOTs and practitioners to use when applying climate science information to inland and coastal H&H design of transportation infrastructure. The guide must be based on defensible climate science and methods, and be focused on engineering practices.
The accomplishment of the project objective will require at least the following tasks.
Task descriptions are intended to provide a framework for conducting the research. The NCHRP is seeking the insights of proposers on how best to achieve the research objective. Proposers are expected to describe research plans that can realistically be accomplished within the constraints of available funds and contract time. Proposals must present the proposers' current thinking in sufficient detail to demonstrate their understanding of the issues and the soundness of their approach to meeting the research objective.
PHASE I — Planning
Task 1. Conduct a critical review of:
· The reports prepared under NCHRP Project 15-61 with an emphasis on the design practices (see Special Note A);
· The NCHRP Project 20-44(23) final report with an emphasis on “themes,” “complexity," and “popularity ratings" in Chapter 4 and the study team’s discussions in Chapter 5 (see Special Note B); and
· The NCHRP Project 20-44(23) “Panelists’ Guidance List” with feedback on the NCHRP Project 20-44(23) DOT proposed revisions (see Special Note B).
Research, evaluate, and document other current appropriate climate risk assessment and design practices from federal agencies that may contribute to the accomplishment of the research objective (e.g., National Oceanic and Atmospheric Administration, U.S. Geological Survey, U.S. Army Corps of Engineers, Federal Highway Administration).
The activities conducted during Task 1 shall focus on updating the existing design practices developed under NCHRP Project 15-61, "Applying Climate Change Information to Hydrologic and Hydraulic Design of Transportation Infrastructure."
Note: Proposers must plan for one virtual meeting with the NCHRP panel at approximately 50% completion of Task 1 to report on the evaluations and information collected so far.
Task 2. Synthesize the information gathered in Task 1. Develop an outline for the guide to accomplish the research objective, including the rationale (e.g., need, impact, required resources) used in the selection of the topics for the outline. Additionally, provide a timeline and cost estimate for the development of the outline to efficiently accomplish the research objective.
Proposers must leverage their knowledge in climate science, inland and coastal hydrology, and hydraulic design engineering, and draw from their experience to build upon the ideas and analyses presented in the available resources above and use them in the development of the outline.
Note on modeling: Because this project addresses the application of climate science for transportation infrastructure, uses climate science tools, and relies on climate model outputs as a core activity of the project, it will be important to convey that these tools and models are being accepted as state-of-the-science products that convey the confidence of the climate science community. Selection of the downscaled global climate model (GCM) and earth system model (ESM) outputs should be made with a well-documented set of objectives explicitly communicated to the panel as part of the contractor’s early reporting, and attention should be given to statistical, dynamic, and hybrid downscaling approaches. The panel is aware that model outputs from the Coupled Models Intercomparison Project, Phase 6 (CMIP-6) have a wider range of values for some variables than those variables in earlier CMIP phases. The panel encourages the proposer to document their evaluation of available downscaled outputs with that wider range in mind and report how the selection of the subset of model outputs was carried out and clearly document the applicability and limitations to various transportation infrastructure assets which require different spatial and temporal resolutions. The NCHRP panel expects that it may have comments on the proposer’s evaluation of available outputs and may engage in discussion with the contractor over evaluation objectives and outcomes.
Note: Plan for one virtual meeting with the NCHRP panel to report on the work performed during Task 2.
Task 3. Prepare Interim Report No. 1 that documents the results of Tasks 1 and 2 and addresses the comments provided by the NCHRP panel. Interim Report No. 1 shall also propose a practical framework for incorporating new analyses and methodologies as these become available to address the dynamic nature of the discipline and provide an updated detailed plan for Phases II and III.
Note: Following a 1-month review of Interim Report No. 1 by the NCHRP, the research team will meet with the NCHRP project panel to discuss the interim report. Work on Phases II and III of the project will not begin until authorized by the NCHRP. Phase I shall be limited to $60,000.
PHASE II — Guide Development
Task 4. Develop the guide according to the approved Interim Report No. 1.
Note: The proposer must plan for at least 3 virtual meetings with the panel to report on the progress of the revisions (e.g., 15%, 40%, and 70% of the development of the revisions). These meetings will not require specific deliverables; however, the proposer is expected to show in detail the approach and progress on the development of the revisions, and to respond to comments submitted by the panel.
Task 5. Prepare a draft conduct of research report that at least includes the following: (1) an annotated outline of the report, (2) the draft guide, and (3) the draft framework to incorporate new analyses and methodologies into the guide.
Note: Following a 1-month review of the draft report by the NCHRP panel, the research team will meet virtually with the NCHRP panel to discuss the draft report. Phase II shall be limited to $290,000. Work on Phase III of the project will not begin until authorized by the NCHRP.
PHASE III — Final Deliverables
Task 6. Present the guide to the AASHTO Technical Committee on Hydrology and Hydraulics for comments and propose revisions to the NCHRP. Revise the guide considering the NCHRP’s review comments and prepare the final deliverables listed in Task 7 no later than 3 months after approval of Phase III.
Task 7. Prepare final deliverables including (1) a conduct of research report documenting the entire research effort and lessons learned, (2) the guide, and (3) a stand-alone technical memorandum titled “Implementation of Research Findings and Products” (see Special Note M).
Note: Phase III shall be limited to $50,000.
