The British Columbia Ministry of Forests, Water Management Branch, Dam Safety Section initiated and managed a project to supplement available hydrology and hydrometeorological information. The goal was to improve the quality, confidence, and accessibility of baseline data about the magnitude and uncertainty of extreme flood events in B.C. This information will be useful for the design of dams, spillways, and dikes as well as linear infrastructure stream crossings.
The guidance and associated products developed for the entire province (the Project) are available in EcoCat's Ecological Reports Catalogue and include:
The Project hydrometeorological deliverables are available from the MetPortal from DTN and include:
The Project flood analysis deliverables include:
Historical flood-related information obtained from local and regional archives was incorporated into the flood frequency analysis of selected streamflow gauges and a methodology for validating such historical information was proposed. In addition, guidance documents have been completed for practitioners to utilize when completing flood studies with the hydrometeorological and flood flow analysis information.
