McElhanney used hydraulic modeling to complete flood modeling and mapping of the Bow River in Canmore, Alberta.
McElhanney assists BC MoTI with river and hydrotechnical engineering services for various bridge, culverts, and bank stabilization projects on 40+ sites.
McElhanney was tasked with designing the Anderson Creek fishway to allow salmon to bypass a bridge apron that has deteriorated into a 3m concrete weir.
McElhanney is providing a wide array of services for this project including structural, civil, and hydrological engineering, environmental, visualization, and arborist services. McElhanney developed the images to help illustrate the project concept.
In December, 2007 the City of Prince George experienced a rapid cold snap which resulted in an ice jam on the Nechako River. A 66-day long local state of emergency was declared and over 100 residents were evacuated from their homes.
During the summer of 2017, BC Hydro’s 60-year old creosote timber dam was completely removed from the Salmon River on Vancouver Island, and the site was re-naturalized. McElhanney designed bypass channels, cofferdams, and river diversion works to use as small a footprint as possible in this narrow and hectic worksite.
