Water Management

These tools support adaptation analysis, planning and implementation in relation to water management.

The tools were supported or created by the Climate Change Impacts and Adaptation Division (CCIAD), Natural Resources Canada. They are made available here in the language of the author, and do not constitute an en-dorsement of content or recommendations.


Water Balance Model

landing page of Website, titled, Water Balance Model

(Web-based Tool) (2012)

This decision support tool, produced by the Partnership for Water Sustainability in BC, bridges engineering and planning by creating scenario models across three levels of drainage site, development and watershed. Through a set of modules, the tool can help users improve urban stream health through rainwater runoff source control evaluation. The climate change module demonstrates future projected impacts (2020, 2050 and 2080) on watershed hydrology in BC and Alberta. Future updates are planned to add other geographic regions to the database for this module.


Professional Practice Guidelines – Legislated Flood Assessments in a Changing Climate in B.C.

cover page of guide, titled, Professional Practice Guidelines – Legislated Flood Assessments in a Changing Climate in B.C.

(PDF, 1.28 MB, 144 pages) (2012)

Prepared by the Professional Engineers and Geoscientists of British Columbia (B.C.), these guidelines present flood assessment procedures, standard and risk-based approaches, and, methods for anticipating climate change and land surface change. The practices are based on legislation in B.C., but can also inform professionals from other regions of Canada.

 A Guide to Water and Watershed Planning for B.C. Communities in the Face Of Climate Change and Other Challenges

HTML (PDF, 2.89 MB, 56 pages) (2011)

This guide, prepared by the Fraser Basin Council, was developed for local governments and community stakeholders in B.C., with lessons learned transferable to other regions. It describes water and watershed planning, including the integration of climate change considerations into managing water supply and demand, and storm-water management plans.


Adaptation Guidelines: B.C. Sea Dikes and Coastal Flood Hazard Land Use

Cover page of case study, titled, Climate Change Adaption Guidelines for Sea Dikes and Coastal Flood Hazard Land Use- Sea Dike Guidelines

(PDF, 4.15 MB, 59 pages) (2011)

This document provides guidelines for the design of sea dikes to protect low lying lands that are exposed to coastal flood hazards arising from their exposure to the sea, and to expected sea level rise due to climate change. It is written for diking authorities and design professionals. Please also note the companion "Guidelines for Management of Coastal Flood Hazard Land Use 2010" (PDF, 956 kb).


Slow it. Spread it. Sink it. An Okanagan Homeowner’s Guide to Using Rain as a Resource

cover page of guidebook, titled, Slow it. Spread it. Sink it. An Okanagan Homeowner’s Guide to Using Rain as a Resource

(PDF, 7.74 MB, 64 pages) (2011)

Created by the Okanagan Basin Water Board, this guide provides homeowners with techniques for evaluating, capturing and controlling rainfall runoff. The methods vary from do-it-yourself solutions to practices which require technical assistance from professionals. This guide can be modified to be used in other regions.
