About the position
The Faculty of Science and Technology has a vacant three-year PhD–position related to urban hydrology and rainfall estimation. The position is affiliated with the research group on water and environmental engineering (WESH group).
Urban rainfall data is needed for urban stormwater management, rainfall-runoff modeling and flash flood nowcasting. These applications may require rainfall data with high temporal ( minutes) and spatial resolution ( 100 meters). Traditional rain gauge networks are typically too sparse to provide the desired spatial resolution. The purpose of the present PhD project is to refine and develop computational methods to augment data from traditional rain gauges with new sources of rainfall data, such as e.g. commercial microwave links (CML) and personal weather stations (PWS).
CMLs are part of the backhaul infrastructure of e.g. telecommunication companies. Rainfall between two antennae in a link will attenuate the signal intensity at the receiving end of the link. In recent years, researchers have developed methods to use the signal attenuation in such links for inferring rainfall intensity along the link. PWSs are affordable privately-owned weather stations that are connected to the internet. Both CMLs and PWSs carry the potential to improve the spatial resolution of urban rainfall maps. In order to make the most of all the available data sources, sophisticated data analysis is needed that considers the characteristics of each data source.
The position is financed by the Faculty of Science and Technology (REALTEK) at NMBU, but the supervisory group will also include experts on stochastic hydrology and geostatistics from the hydrology group at NMBU and INRAE in France. An extended project reference group will be established in cooperation with the Norwegian Meteorological Institute and the Norwegian Water Resources and Energy Directorate.
A detailed project plan will be developed in collaboration with the candidate, but the following are likely components of the project
- Test and refine CML attenuation-to-rainfall algorithms using Norwegian data
- Test and refine algorithms for reconstructing spatio-temporal rainfall fields from CML data
- Test and refine algorithms for combining urban rainfall information from multiple sources in an optimal manner
- Assess the potential improvement in urban rainfall maps in Norway by augmenting traditional rain gauges with new data sources
- Assess the improvement in urban rainfall-runoff models by using a richer set of rainfall data as model input
- Publish results in international scientific journals
- Disseminate results to stakeholders in Norway
The successful candidate is expected to enter a plan for the progress of the work towards a PhD degree during the first months of the appointment, with a view to completing a doctorate within the PhD scholarship period.
