2018-Sahani Pathiraja

Project description

2015-2018

Sahani was one of our own undergrads who completed an outstanding PhD recently and is now a postdoc in Germany. She worked on Bayesian data assimilation, supervised by Lucy and Ashish and Hamid Moradkhani from Portland. Her work is one of the first to develop assimilation alternatives that are designed for use in hydrology, instead of just being ported over from the maths field they originated for. The papers from her PhD till date are:

Moradkhani (2018), Insights on the impact of systematic model errors on data assimilation performance in changing catchments, Advances in Water Resources, In press (accepted 15/12/2017), doi:10.1016/j.advwatres.2017.12.006.
