EGBC Practice Advisory on determining dam hydrological loading

Engineers and Geoscientists BC (EGBC) issued a practice advisory in 2022 for registrants who provide service related to dam hydrological loading. This Practice Advisory on Dam Hydrological Loading (PDF, 185KB) provides information to develop dam hydrological loading estimates.

B.C. Extreme Flood Project

The B.C. Extreme Flood Project supplements available hydrology and hydrometeorological information. The guidance documents and project deliverables are useful for the design of dams, spillways, dikes, and stream crossings.

These include the:

  • B.C. Regional Flood Frequency Analysis Portal that shows locations of hydrometric stations and corresponding drainage areas analyzed to estimate peak flow events
  • MetPortal that hosts Probable Maximum Precipitation (PMP) data along with spatial and temporal patterns of Probable Maximum Storms (PMS) across the province

Previous outdated PMF Guidance

The previous guidance for generating Probable Maximum Floods (PMF) in British Columbia is no longer recommended. The 2010 PMF Estimator for BC (3.8MB) report is for reference only. It should only be used to provide a preliminary estimate of PMFs or as a rough check on detailed PMF analyses.
