Flood Engineering in Toowoomba
Overland flow and flash-flood modelling, Flood Impact Assessments and Toowoomba Regional Council development support.
Toowoomba's steep escarpment catchments and rapid overland flow make flood engineering here a specialist task. CWD Group builds TUFLOW models tuned to the fast-responding creeks and overland flow paths that run through the city and the Darling Downs, and delivers RPEQ-certified Flood Impact Assessments that meet Toowoomba Regional Council's requirements. We handle single-lot assessments, subdivision flood studies, and overland flow path investigations for development applications across the region.
Frequently Asked Questions
Why is flood engineering different in Toowoomba?
Toowoomba sits on a steep escarpment with fast-responding catchments, so flash flooding and overland flow dominate rather than slow mainstream river flooding. Our TUFLOW models are set up to capture that rapid, high-velocity behaviour, which is what Toowoomba Regional Council assessors are looking for.
Do you work with Toowoomba Regional Council mapping?
Yes. We start from Toowoomba Regional Council's flood mapping and planning scheme overlays, check their relevance to your site, and build a site-specific model where the proposal could affect overland flow or flood levels.
