Excerpts from the Design Flood Hydrology Event for BC Natural Resource Professionals on March 28, 2017.
|Canadian Standards Association||CSA PLUS 4013-2019 Technical Guide: Development, Interpretation And Use Of Rainfall Intensity-Duration-Frequency (IDF) Information: Guideline For Canadian Water Resources Practitioners|
This guide is aimed at increasing the understanding of rainfall intensity-duration-frequency (IDF) information in derivation, and application in water system planning and design. This Guideline is intended to equip the reader with the ability to ensure that rainfall IDF characteristics are properly considered in the planning and design of water infrastructure. It includes a methodology of deriving IDF curves by factoring in future projected temperature changes.

|City of Vancouver||City of Vancouver Rain City Strategy|
The target of the Rain City Strategy is to capture and clean 90% of the rainwater that falls in Vancouver. The strategy includes deployment of green infrastructure approaches in a range of transportation and street redesign projects, sewer projects, parks, and private site developments to take strides toward becoming a water-sensitive city.
|FPInnovations||Adapting Resource Road Infrastructure to Climate Change|
The changes to climatic conditions in Canada are anticipated to have a significant impact on the Canadian forest industry. Resource roads are considered vulnerable to the immediate and short-term impacts of climate change. These resources present the risks and vulnerabilities of resource roads to climate change and suggested adaptation methods and practices.
|Environment and Climate Change Canada||Intensity-Duration-Frequency (IDF) Tools|
Environment and Climate Change Canada provides official IDF information based on precipitation data from weather stations across the country and has made it available for the public.

|Metro Vancouver||Intensity-Duration-Frequency (IDF) Tools|
Metro Vancouver has released a study (August 2018) of the impacts of climate change on precipitation and stormwater management (future IDF curves). The report is now available along with a short 4-page brief.
|University of Western Ontario||Intensity-Duration-Frequency (IDF) Tools|
Maintained by the University of Western Ontario, this computerized web-based IDF tool integrates a user interface with a Geographic Information System. By creating or selecting a station (Gauged IDF) or selecting a location on the map (Ungauged IDF), the user will be able to carry out statistical analysis on historical data, as well as generate and verify possible future change based on a methodology using a combination of climate modelling outputs and locally-observed weather data.
Note: The IDF CC Tool assumes that the historical scaling between sub-daily and daily events holds going forward in the future and this assumption may not be true. For this reason it is possible that the tool could underpredict sub-daily events.

|U.S. Climate Resilience Toolkit||Find information and tools to help you understand and address your climate risks.|
Supported by the Water Partnership Program, this book summarizes alternatives explored by a group of organizations that belong to the Alliance for Global Water Adaptation (AGWA), to provide practitioners with the tools to adapt to the realities of climate change by following a decision-making process that incorporates bottom-up thinking.
Using Demonstration Storms to Prepare for Extreme Rainfall
This storm transposition simulation tool developed by scientists at the University of Wisconsin, uses NOAA NEXRAD rainfall radar data from any recent rainfall event to demonstrate what would happen if the event occurred in other locations. This helps planners discover unforeseen vulnerabilities and adaptation opportunities. The simulated storm helps municipalities and businesses recognize steps they could take to minimize the impacts of future extreme storms.
|Washington Department of Fish and Wildlife||Integrating Climate Change into the Design of Water Crossing Structures|
Washington State has developed a document addressing climate change and the design of stream crossings. It addresses two analytical challenges: 1) translating future climate projections generated by global climate change models into information that can be directly applied to the design of water crossing structures in the Washington State, and 2) presenting quantitative results in a way that usefully conveys uncertainty and risk to decision makers and various stakeholders.
|Water Survey of Canada||BC Hydrometric Program Network|
This long-term water quantity monitoring network of 450 hydrometric stations, operated by the Water Survey of Canada, is co-managed under a Federal-Provincial Agreement by the BC Ministry of Environment and Climate Change Strategy, and Environment and Climate Change Canada. It is supported by partnerships with provincial agencies (5 stations), BC Hydro (99 stations), local governments (22 stations), First Nations (1 station), and industry (13 stations).
