Description

This information letter presents the results and recommendations of a research project undertaken for the Reclamation Research Technical Advisory Committee to: define the terms "abandoned", "suspended" and "orphan" as used by industry and government; estimate numbers of wellsite abandonments at present and to be expected over the next 10 years; and estimate surface reclamation costs.

Description

This study delineates flood hazard areas and determines design flood levels along an approximate 13 km reach of Sawridge Creek through Slave Lake as well as almost 5 km along the Sawridge Creek flood control channel. The study incorporates flow interactions between Lesser Slave Lake, the Lesser Slave River, Sawridge Creek and the flood control channel. The design discharge for Sawridge Creek is 170 m³/s upstream of the flood control channel and 83.0 m³/s downstream of the channel. The design discharge for the flood control channel itself is 87.0 m³/s. The study was prepared in March 1993. Flood information available after study completion may not be reflected in the current flood hazard study report or flood hazard mapping.

Description

This study delineates flood hazard areas and determines design flood levels along the Bow River and Policeman Creek through Canmore. The study area includes an approximate 20 km reach of the Bow River and an almost 6 km reach of Policeman Creek. The design discharge for the Bow River is 673 m³/s upstream of the Policeman Creek confluence and 698 m³/s downstream of the confluence. The design discharge for Policeman Creek ranges from 95.8 m³/s at the Bow River confluence to 37.2 m³/s farther upstream, in a non-overflow area. The study was prepared in March 1993. Flood information available after study completion may not be reflected in the current flood hazard study report or flood hazard mapping.

Description

This study delineates flood hazard areas and determines design flood levels along an approximate 7 km reach of Pincher Creek and an approximate 3 km reach of Kettles Creek through the Pincher Creek. The design discharge for Pincher Creek is 179 m³/s upstream of the Kettles Creek confluence and 216 m³/s downstream of the confluence. The design discharge for Kettles Creek is 33.4 m³/s at Highway 6 and 37.3 m³/s at its confluence with Pincher Creek. The study was prepared in March 1993. Flood information available after study completion may not be reflected in the current flood hazard study report or flood hazard mapping.

Description

The Canmore Flood Risk Mapping Study was conducted as part of the Canada-Alberta Flood Damage Reduction Program to prepare flood risk maps for a 20 km reach of the Bow River from the Banff National Park boundary, through the Town of Canmore,to downstream of Dead Man Flat. This study is concerned with only surface flooding caused by open-water floods. Potential flooding because of groundwater was not investigated. A review of historical flooding int he study area indicates that recent flood events, including the 1974 flood, have return periods lower than five years based on the hydrologic assessment by Alberta Environment, Hydrology Branch. The review also indicates that ice-related flooding has rarely occurred through the Town of Canmore.

Description

This technical discussion pertains to observations on petroleum contamination of mineral soils and regolith materials. The discussion of guide values for assessment and remediation purposes is restricted to surficial soil materials -- roughly the first meter of surficial material which is biologically active and represents a direct exposure potential for humans.

Description

This study delineates flood hazard areas and determines design flood levels along the Athabasca River, Muskeg Creek and the Tawatinaw River through Athabasca. The study area includes an almost 6 km reach of the Athabasca River, an almost 1 km reach of Muskeg Creek and an approximate 3 km reach of the Tawatinaw River. The design discharge for the Athabasca River is 6200 m³/s. The design discharges for Muskeg Creek and the Tawatinaw River are 30.0 m³/s and 65.0 m³/s respectively. The study was prepared in March 1993. Flood information available after study completion may not be reflected in the current flood hazard study report or flood hazard mapping.
