Flood Management and Stream Rehabilitation

Mark Creek Flume Flood Management and Rehabilitation

Aqua-Tex Scientific Consulting, acting as project managers for the City of Kimberley, BC retained LaCas Consultants and Exp Services for the joint design and construction review of a replacement channel for the Mark Creek Flume Flood Management and Stream Rehabilitation Project.  The purpose of the project was to combine engineering with biology in order to replace 180 lineal metres of failing concrete flume (construction in the 1950s) with an enhanced flood channel.  Hydrological and hydraulic modeling was carried out ot determine the water surface profiles within the flood channel including weirs, a ow flow channel and ponds.  A second phase extending 200 m upstream has also been designed and is awaiting construction approval.

Village Hazard Assessment

Village Hazard Assessment

Mount Cook village, a major tourist destination in New Zealand’s Southern Alps, comprises a large hotel complex and supporting residential and commercial facilities.   A previous study had reported a significant risk of debris flow and flood hazards immediately upslope of the development and proposed major preventative measures or relocation of the hotel.  EBA Engineering Consultants Ltd and Graham Rawlings Consulting Ltd. In association with LaCas Consultants were retained by the Department of Conservation (Te Papa Atawhai) to reevaluate the debris flow problem, recommend that best means of protecting the village, and advise on land use planning with respect to natural hazards.  It was concluded that debris flow protection could be achieved using remedial training dykes.

Wetland Restoration

The District of Saanich retained LaCas Consultants (Brian LaCas P. Eng.) to design a multiyear phased restoration project on the Quicks Bottom wetland that was diked and farmed in the 1930s and overgrown with rye grass.  Three finger channels were constructed into the wetland using a hydraulic excavator to construct a corduroy log road extending 70-100m. Upon retreat, the channel was excavated, and the corduroy road logs were placed as large woody debris.  The finger channels help Colquitz Creek flow back into and out of the wetland, restoring it to pre-farming conditions.
