This report identifies a method to estimate an ecologically-based flow regime on the basis of reductions from natural flow or the per cent exceedance from natural flow. It also provides background... More ≫

Description

This report identifies a method to estimate an ecologically-based flow regime on the basis of reductions from natural flow or the per cent exceedance from natural flow. It also provides background information and a jurisdictional review of current environmental flow (instream flow needs) knowledge in North America and international rivers. The report was prepared in support of outcomes and goals identified in the provincial Water for Life strategy and action plan.

Description

This synthesis report builds on information generated during the Northern River Basins Study. It presents information from the Northern River Ecosystem Initiative to give a new benchmark on the present health of the northern river basins. The report also provides an update on development in the basins, and describes initiatives, policies, partnerships, regulations, monitoring, research and other programs implemented to protect the environment. Results of more than 20 scientific projects undertaken during the five-year study are summarized, and a discussion and conclusions about what has been learned is presented.

Description

The Northern Rivers Ecosystem Initiative (NREI) was a five-year endeavor by the governments of Canada, Alberta, and the Northwest Territories to address commitments made by the three governments in response to the preceding Northern River Basins Study (NRBS). The NRBS was itself a five-year initiative to obtain information regarding the existing conditions in, and the effects of development on, the aquatic ecosystem of the Peace-Athabasca-Slave river basins. The NREI involved scientists and resource managers from governments, universities, industry, and other organizations. Highlights of their actions are included in this report, with further detail available in various technical science reports.

Description

The governments of Canada, Alberta and the Northwest Territories established the Northern Rivers Ecosystem Initiative to answer questions and address recommendations from the Northern River Basins Study, which took place between 1992 and 1996. The initiative was a science-based effort to gain more information to help understand the impacts of human activities on aquatic ecosystems in this region of Canada's north. This resource provides a general summary of the findings of the initiative. It also included are references to other studies and monitoring programs done during these years.

Emergency/process upset flaring management : modelling guidance

Description

This guidance is intended for flare operations that require an Environmental Protection and Enhancement Act approval, or that operate under a code of practice for emissions to the atmosphere.... More ≫

Description

This guidance is intended for flare operations that require an Environmental Protection and Enhancement Act approval, or that operate under a code of practice for emissions to the atmosphere. Alberta Environment has developed the guidance to ensure consistency in the use of dispersion models for regulatory applications in Alberta. The practices recommended within this guideline are a means to ensure that these objectives are met. The guideline outlines Alberta Environment's dispersion modelling requirements and methods.

Acceptable salinity, sodicity and pH values for boreal forest reclamation

Description

This report examines plant species used in reclamation and their tolerances for soil salinity, sodicity and pH. The information for each species was obtained from a review of the literature and... More ≫

Description

This report examines plant species used in reclamation and their tolerances for soil salinity, sodicity and pH. The information for each species was obtained from a review of the literature and unpublished information conveyed through personal interviews with people conducting research in this area or working in reclamation. The objective of this report is to determine if the current values for soil salinity, sodicity and pH need to be revised to reflect plant species' tolerances for these soil parameters. The results indicate that the current values used for soil salinity, sodicity and pH should not be changed at this time.
