Julian OrthProfile

Julian specialises in providing technical advice in riverine flooding and stormwater management. Using his technical skills in numerical modelling of hydrologic, hydraulic, and water quality processes, he has developed flood impact, stormwater management, water balance and stream diversion studies for numerous urban development and mining projects.

Julian is focused on delivering economical and environmentally sustainable engineering solutions for projects ranging from small sub-division developments to catchment-scale stormwater trunk drainage studies and mine-related environmental impact statements. He has worked on projects in almost all states and territories of Australia and in New Caledonia. 

Julian was the senior flooding and stormwater quality modeller for the Fitzgibbon Urban Development Project, which won the 2012 Water Sensitive Urban Design (WSUD) award through the Healthy Waterways Partnership.

In 2013, he completed a Masters of Engineering Science, which included a project that investigated the hydrodynamics and water quality impacts   of the Stage 3 Hinze Dam Wall Raising on the Gold Coast.
