Roslyn Luyt

Organized and adaptable candidate with expertise in ArcGIS and QGIS packages. Thorough understanding of multiple industries including project management, engineering, manufacturing, building and construction. Willingness to learn and take on added responsibilities to effectively meet project goals and client expectations. Experience in managing teams and subcontractors. Proficient in mathematical spatial statistics, satellite analysis, visualisation and interpretation of data.

I have completed a yearlong capstone thesis, ending in July 2020 on Direct Rainfall Method (DRM) 2D hydrodynamic modelling; utilising both TUFLOW Classic and TUFLOW GPU (HPC). Direct Rainfall Method (DRM) or Direct Rain on Grid is a new and upcoming method on doing both hydrologic and hydrodynamic modelling simultaneously. The desktop study model area was located west of Mackay in the Kinchant Basin. Historical daily rainfall data was used and expanded out in MatLAB to create workable pluviograph data, due to financial constraints of the research. My supervisor Prasanna Egodawatta asked me to investigate using Direct Rainfall Method and compare it to the conventional 1D lumped hydrologic model coupled with a hydrodynamic model in TUFLOW Classic. The summary of the outcomes of the research are as follows: 

• Both TUFLOW Classic and TUFLOW GPU (HPC) use slightly different numerical solvers and they have different applications of use.
• Even though both models had the same input data from a hydrological model in HEC-HMS, both models showed completely different results.
• The TUFLOW GPU (HPC) was closer to the historical discharge data measured at the control weir located at the most down-stream point of the catchment.
