Reinert Huseby Karlsen

Reinert Huseby Karlsen holds a doctoral degree in hydrology and has more than 10 years of experience in hydrological research and investigations. His academic research has focused on catchment scale runoff processes, and the importance of landscape composition for partitioning of water, water storage and runoff dynamics.


Reinert works mainly with data analysis, geographical information systems (GIS), field measurements and hydrological modelling. He is an expert on field measurement techniques for surface water, as well as the processing, quality control and quality assurance of water discharge timeseries. He works on several projects related to stream gauging, for example towards the mining industry and catchment science research in boreal landscapes. He enjoys expanding his programming skills, and makes extensive use of Python for data management, analysis, modelling and general purpose programming. Apart from extensive field experience within a Nordic setting, he has also worked abroad in the Netherlands and Mexico.
