Dr Ben Jarihani


Dr Ben Jarihani joined USC in October 2015 as a post-doctoral Research Associate on a project supported by CSIRO working on catchment hydrology modelling in gully-dominated savanna ecosystems. In this project he is integrating both ground and drone-based Structure from Motion surveys into research that will articulate hydrologic pathways that contribute to gully initiation and expansion. After completing his Bachelor's and Master's degrees in water resource engineering in Iran, Ben worked for a long period as a hydrologic engineer prior to immigrating to Australia. Thereafter he received a degree in GIS then proceeded to complete a PhD in physical geography at UQ in 2015. His PhD research focused on novel applications of remotely sensed data in hydrodynamic modelling of large, dryland catchments of central Australia, which experience episodic flooding, but have sparse data. He also worked on a shorter-term research project on groundwater recharge estimation at UQ, which benefited from his analytical skills related to spatio-temporal data.

Dr Jarhani's excellent skills in GIS and remote sensing also add new dimensions to his research projects in hydrological science. He has developed excellent skills in hydrological modelling in ungagged basins using Geographical Information Systems and remotely-sensed datasets. Ben has experience in acquisition, manipulation, editing, analysis and maintenance of spatial datasets using a range of software products (Google Earth Engine, ERSI ArcGIS Suite, ILWIS GIS, ENVI, ARCHydro GIS, HEC-GEOHMS). He is also an experienced field data collector and has been successful in designing, project management, establishment, calibration and maintenance of hydrological monitoring systems.

He is passionate about his work in hydrological science and has published three publications from his PhD in Journal of Hydrology and numerous parers are prepared or are in progress from his USC-CSIRO project. He has involved in teaching and student supervision during his PhD and postdoc programs.
