Flood Frequency Analysis (FFA) Manual for Hydrotechnical Practitioners in Canada

Flood Frequency Analysis (FFA) Manual for Hydrotechnical Practitioners in Canada Solicitation Number: 5000075974

The Flood Hazard Identification and Mapping Program (FHIMP) is an initiative of the Government of Canada with the goal of helping Canadians better plan and prepare for future floods. As a contributor to the FHIMP, Environment and Climate Change Canada (ECCC) provides guidance and best practices for hydrology, hydraulics, climate change impacts, and uncertainty. Under this mandate, ECCC is working to deliver an instructive manual for engineering and hydrology practitioners outlining methods to calculate a Flood Frequency Analysis (FFA). FFA provides information about the magnitude and frequency of flood discharges based on recorded data. The most common method for flood frequency analysis is to fit an extreme value distribution to an annual maximum series of peak flow data. This is appropriate in many cases; however, there are several under-utilized FFA methods that may be more appropriate in specific situations in Canada.

The objective of the Work is to create and develop a reference manual for hydrotechnical practitioners in Canada to assist with preparing for future floods in Canada. The manual will describe various flood frequency analysis methods, their application (including worked examples for each method), limitations, input variables to the method and how to obtain the variables, and the tools currently available to complete the analysis.

The Contractor must draft a reference manual for the intended audience of hydrotechnical practitioners in Canada. The Contractor will explore various methods to complete a FFA as outlined in Tasks 1 and 2. Each method must be described in its own section of the manual and must include, but not be limited to, the following:

a. Description of the method including cases in which the method should be applied, and strengths and weaknesses of each method. b. A worked example on real gauged data (or appropriate real data for the methods that do not use gauged data). The selected example data should highlight the intricacies of that method. c. Lists of computer code and/or software options available to carry out the FFA for each method, and assessment of these options. d. A decision tree or flowchart indicating which method should be followed for FFA for any given project location or hydrologic inputs. Practitioners will utilize this resource to determine the method they should follow for any given project. The contract is for a period of approximately six (6) months with the possibility of an additional six (6) months.
