Hydraulic Impact Assessment

Springbrook Stage 4 and 5

Location: Springbrook, QLD

Client: QM Properties Pty Ltd


Premise was engaged to prepare a Hydraulic Impact Assessment to investigate the pre-development, and mitigate post-development, flood scenarios for a range of design flood events. Hydrologic and hydraulic models (XP-SWMM) were developed, validated, and tested for the catchment encompassing the site.

Two creek crossings were modelled and crossing infrastructure was optimised to convey flows with no worsening of flood conditions to surrounding properties in a more cost-effective manner than the original design. Premise delivered this project on time and on budget, in accordance with our Quality Assurance certification.
