Ann KretzschmarPhD student, Associate Lecturer
My PhD project uses Inverse Hydrology in the form of regularisation of a cotinuous time transfer function model (identified using data based mechanistic modelling techniques) to infer catchment rainfall. The temporal resolution of the resulting rainfall sequence has been investigated using spectral analysis and future work includes investigation of spatial rainfall patterns and identification of data that provides disinformation to the modelling process. Identification of disinformative data may help reduce the uncertainty in forecast made using the models identified.
