D. (Derya) Sadak MSc



My main focus was about wastewater load allocation (WLA) approaches and I worked as a project assistant that is supported by TUBITAK (The Scientific and Technological Research Council of Türkiye). I was interested in both stochastic and deterministic optimization methods like DE, PSO, LM, HS, GA, CG coding with Matlab. After 2019, I continued my PhD degree and I focused on calibration and validation of mHM (mesoscale hydrological model) for Susurluk Basin.

I am currently a PhD researcher in the Water Resources Section. Before joining TU Delft, I had been working as a research assistant in Türkiye for over 3 years. In 2019, I finished my MSc degree in Water Resources Management and obtained my BSc degree in the Civil Engineering Department at Pamukkale University.
